This dissertation introduces and develops a new method of rational reconstruction called structural heuristics. Structural heuristics takes assignment of structure to any given object of investigation as the starting point for its rational reconstruction. This means to look at any given object as a system of relations and of transformation laws for those relations. The operational content of this heuristics can be summarized as follows: when facing any given system the best way to approach it is to explicitly look for a possible structure of it. The utilization of structural heuristics allows structural awareness, which is considered a fundamental epistemic disposition, as well as a fundamental condition for the rational reconstruction of systems of knowledge. In this dissertation, structural heuristics is applied to reconstructing the domain of economic knowledge. This is done by exploring four distinct areas of economic research: (i) economic axiomatics; (ii) realism in economics; (iii) production theory; (iv) economic psychology. The application of structural heuristics to these fields of economic inquiry shows the flexibility and potential of structural heuristics as epistemic tool for theoretical exploration and reconstruction.

Questo lavoro esamina se e a che livello la credibilità dell’assetto istituzionale e delle azioni dei policy-maker influenzano la produzione di eco-innovazione. Dopo una revisione della letteratura che incrocia ambiti teorici diversi, si evidenzia una caratteristica trasversale agli strumenti di politica ambientale, in particolare quella della credibilità, e se ne testa l’effetto sull’eco-innovazione. L’ipotesi centrale di questa tesi, che la credibilità impatti positivamente sulla produzione di eco-innovazione nel sistema economico, viene testata con un’analisi qualitativa e quantitativa sul caso studio della regolamentazione europea sulle emissioni automobilistiche (1980-2007). I risultati confermano l’ipotesi, evidenziando un percorso parallelo tra la produzione di eco-innovazione, misurata in termini di brevetti, e le variazioni nella credibilità della regolamentazione conseguenti a specifiche azioni intraprese a livello comunitario. L’ipotesi è confermata anche dallo studio quantitativo che evidenzia un impatto statisticamente significativo e positivo per l’indice di credibilità proposto. Si conclude suggerendo che UE e paesi membri trarrebbero benefici da una rinnovata attenzione alla credibilità delle politiche ambientali, fondata sull’indipendenza dagli attori economici coinvolti e, in particolare, su una migliore qualità della regolamentazione stessa. Si stima che la conseguente percezione di stabilità ed efficienza migliorerebbe il risultato delle politiche ambientali in termini di eco-innovazioni prodotte dalle imprese. / This thesis investigates whether and to what extent regulatory credibility influences the production of eco-innovation. After a selective literature review that analyzes the concept of eco-innovation through the principles of environmental economics, innovation economics, and regulatory economics, we contribute to the current literature by highlighting the role of a specific regulatory feature, that of credibility. Our hypothesis of a positive impact of regulatory credibility on eco-innovation is confirmed by a case study on the European car emissions regulation (1980-2007), which has been carried out by combining a qualitative and a quantitative approach. The findings indicate a common pattern of eco-innovation, which is measured by patent count, and of the credibility of the EU as car emissions regulator. The quantitative analysis estimates a statistically significant and positive impact of our credibility index on eco-innovation. Our conclusion is that the EU and each Member State would benefit from a new focus on building credible regulatory regimes, based on increasing independence from the industry pressure and on high regulatory quality. The consequently perceived stability and efficiency of the regulation is expected to improve the outcome of environmental policies in terms of eco-innovations produced by industry itself.

The present work is organized in five chapters and it proposes and applies alternative measures of productivity constructed using input-output tables and based mainly on the Sraffian scheme. The first three chapters of the thesis are devoted to the development and the empirical application of new productivity measures. These chapters form the main part of the work. The last two chapters are devoted to sensitivity analysis. In the first chapter, entitled ‘Productivity accounting based on production prices’ an alternative method of productivity accounting is proposed. By using input–output tables from four major OECD countries between 1970 and 2000, we compute the associated wage-profit frontiers and the net national products curves, and from these we derive two measures of productivity growth based on production prices and a chosen numeraire. The findings support the general conclusions in the existing literature on the productivity slowdown and later rebound, and supply new important insights to the extent and timing of these events. The second chapter is entitled ‘New measures of sectoral productivity’. The objective of this chapter is to propose alternative methods of sectoral productivity accounting based the theoretical work of Goodwin (1976), Gossling (1972), Pasinetti (1973), and Sraffa (1960). The indexes developed in this study differ from the standard indexes of productivity because they are designed on the basis of some of the following desiderable features: take into account the interconnections among economic sectors, aggregate heterogeneous goods by using production prices, and compute productivity by using quantity of goods instead of their values. These indexes are then be tested empirically by computing productivity of four major OECD countries. The third chapter is entitled ‘Productivity in the Italian regions: development of Alternative Indicators based on input-output tables’. This chapter calculates indices of aggregate productivity, sectoral productivity, and technological progress for a selected sample of Italian regions. Besides these indices, two different versions of the so-called technological frontier were calculated. The contemporary frontiers that are constructed from all the production techniques extracted from the regional input-output tables in a given year and the intertemporal frontier that is computed for the full set of techniques available over time and across regions. The availability of the technological frontiers allows the calculation of the recently developed Velupillai-Fredholm-Zambelli indices of convergence (Fredholm and Zambelli, 2009) that are based on the distance between the region-specific wage-profit frontiers and the technological frontiers. Given the important role played by the production prices, this chapter also examines the price curves for each region and industry and it identifies remarkable regularities. Not surprisingly, analyses of the findings reveal that there is a productivity gap between the regions of North and South. However, the analysis of sectoral productivity reveals two important facts. The first is that the techniques of some industries are more productive in the South than in the North. The second, who follows from the first, is that all regions could therefore improve productivity through greater integration. Chapter four is entitled ‘An Inquiry into the choice of Numeraire’. This chapter has several objectives. The main aim is to examine the robustness of the results obtained by applying the new approach to measuring productivity if we change the numeraire chosen. However, it should be mentioned that the problem of the choice of numeraire is a general one and for this reason, the chapter also proposes universal guidelines to be followed in choosing the numeraire and in testing the robustness of the results to changes in the numeraire. Finally, chapter five is entitled ‘An Inquiry into the effect of aggregation of input-output tables’. The aim of this chapter is to test the robustness of the results from a progressive aggregation of the input-output tables.

The overall goal of this work is to study the effect of a crisis on the distribution and employment and the space of manoeuvre of the government for supporting and reverting the negative shock produced by such a crisis. Every chapter of this work and the related models are supported by both a theoretical background analysis and by numerical dynamic simulations. Stylized facts show that the income and wealth inequality in all the OECD countries has been constantly increasing after the 1960s. Piketty has been one of the most important authors that highlighted the rising inequality issue, mainly in the OECD countries. For example, Piketty (2014) shows that the income share held by the top percentile in countries such as US, Canada and UK increased from 8%-10% in the 1960s up to 14%-18% in the current decade. Similar figures are now provided by the World Inequality Lab that has updated data for almost every country up to 2016. At the same time, the wage share for the majority of the OECD countries substantially decreased. For example, countries such as Italy and Spain experienced a decrease in wage share from about 73% in the 1970s to about 63% in the current decade (Hein, 2014). Taking into account such a stylized fact, we will consider a model with two social classes, workers and capitalists. These social classes differ in terms of their initial endowment, their consumption behaviour, the different loans repayment conditions required to them by the banks and in terms of the ways in which they can use their financeable wealth. This is a very important departure hypothesis from the mainstream point of view models that generally consider a population made up of “a representative agent” of the whole society. Considering the inequality levels that the OECD countries are experiencing, we took the Post-Keynesians school of thought as a very good reference point since it always focused its attention on the relation between the level of employment, the aggregate demand and the distribution between social classes. In line with the post-Keynesians tradition, we believe that a theory cannot be correct unless it starts from realist or realistic hypotheses, although it is recognized that assumptions are always abstractions and simplifications (Lavoie, 2014). Therefore, we developed a step by step model with the analysis of an economy based on some well-known stylized facts. Beyond the social classes distinction, we take into consideration the temporal lag between production and sales of products by firms and the one between income received by the social classes and their expenditure. Those two temporal lags are the very key aspects we focus our attention on in the model presented in Chapter II named “Keynes, Kalecki and Metzler in a Dynamic Distribution Model”. In that chapter, we merge the hints of Keynes and Kalecki about the distribution of social classes and the intervention of the government in supporting the aggregate demand together with Metzler’s hint about the mismatching process between aggregate demand and aggregate production. Metzler’s mismatching process would finally generate inventories of consumption goods. More specifically, it is argued that even if Post-Keynesians models focused their attention on output growth, employment and income distribution relating those issues with a stronger intervention of the state, they all (even the canonical Kaleckian model) overlooked the adjustment - or non-adjustment - dynamics from the ultra-short run to the short run period upon which the short run and long run models are then constructed. In fact, even if the Kaleckian models completely reject the standard neoclassical production function (rejecting diminishing returns and rejecting the substitution between capital and labour) they also very strongly rely on a final equilibrium between aggregate demand and aggregate production. The canonical Kaleckian short run models are constructed upon the consideration of the effective labour demand curve defined as “the locus of combinations between real wages and levels of employment which ensure that all produced goods are sold at the price set by firms” (Lavoie, 2014). As argued by Lavoie (2014), this construction assures that an increase of real wage leads to an increase in the employment level. That has been and still is definitely one of the cornerstones for the Post-Keynesian authors. We argue that the equilibrium assumption between the aggregate demand and the aggregate production plays a key role in obtaining the standard Kaleckian conclusions regarding the relation between effective demand, employment levels and the distribution of surplus product between the social classes. The main question arising from the previous enquiring exercise about adjustment dynamics in the Kaleckian framework is that, because of the overlooking on that adjustment process between aggregate production and aggregate demand, also its conclusions might be consequentially affected. More precisely the main Post-Keynesian Kaleckian conclusions to assess are the following: would it still be true that higher real wages lead to a higher level of employment? Would it still be true that a decrease in the propensity to save will lead to an increase in output and employment? Would it still be true that in order to keep employment from falling, whenever there is an increase in productivity there must be some increase in real wages? And finally, most importantly in terms of policies, would it still be true that in order to keep employment from falling, even when the economy faces a pari passu increase of real wage and productivity level, it would be necessary an increase in real autonomous expenditure such as a strong government one? In this way, our model analyses under which conditions the standard Kaleckian conclusions are still valid considering a disequilibrium situation. Two scenarios are simulated: one with fixed expectations as in Metzler (1941) and another new one based on adaptive expectations and asymmetric behaviour of the wages-unemployment relation. The model questions the effective demand labour curve and suggests that an increase in real autonomous expenditures, mainly by the Government, might be even more essential than what is generally considered in the Kaleckian literature, to avoid increasing unemployment in an increasing wage world. The model presented in Chapter III named “The stabilising role of the Government in a Dynamic Distribution Growth Model” builds upon the model presented in Chapter II and considers once again the effect of a crises on the relation between aggregated demand, employment and distribution between social classes adding important characteristics of realism that were absent in the previous chapter. Here, we consider the gestation period of the investments and the presence of the government investigating its margin of manoeuvre in such an economy. The first aspect takes inspiration by Kalecki (1971) himself who considers the three different Investment stages: investment order or Demand (I^D), investment Production (I^P) and investment delivery or Completion (I^C). In line with a post-Kaleckian perspective, we consider the expected profitability and the capacity utilisation as the two main variables as driving forces for the investment decisions. The second new aspect of this model compared to the one presented in Chapter II is the explicit presence of the government. In fact, even if chapter II suggested the Government as the emblematic autonomous figure able to foster expenditure in times of recession, its actual role in the economy was not analysed. Many post-Keynesian scholars have underlined how recent decades have been characterised by a strong downgrading of the fiscal policy role as a stabilisation instrument of macroeconomic policy (Arestis and Sawyer, 2003). In this way, this chapter analyses exactly the space of manoeuvre of the government and the role of the fiscal policies into a “functional finance” framework where the government "can and should be called upon as a key part of the remedy" (Fazzari, 1994) to ensure a high level of economic activity whenever the private sector is unable to do so by itself. In the light of such a functional finance framework, the government actions should be inspired to achieve a more stable and sustainable growth path. More specifically, we here investigate the possibilities that the Government has to boost and support the economic activity with its two main tools, public investments spending and a taxation system in two scenarios. The first scenario simulates an exogenous fall of private investments while the second one relates to an exogenous increase in labour productivity and real wages. In particular, here we test the canonical Kaleckian model conclusion according to which even when the economy faces a pari passu increase of real wages and productivity level it would be necessary an increase in real autonomous expenditures - such as the one implemented by the government - in order to keep employment from falling. At the same time, the aim of this chapter is also to explore the role of the Government in stabilising the economy exactly thanks to the previous tools. In fact, Chapter II underlined the possibility of an arising unstable path from a mismatching dynamic between aggregate demand and aggregate production. It was argued that such an unstable path might develop because of “wrong” oversensitive expectations of firms regarding the production of consumption goods. Therefore, chapter III focuses exactly on the space of manoeuvre of the government in stabilizing an unstable economic scenario caused by a crisis. The model built in Chapter IV named “The distributive monetary analysis of a sustainable ecological economy” is the natural evolution of the models developed in Chapters II and III. In such a model all the previous stylized facts are contained, namely the temporal lag between production and sales of products by firms, the temporal lag between income received by the social classes and their expenditure, the gestation period of the investments and, finally, the intervention of the government. The most important difference with respect to the models presented in the previous chapters is its overall monetary and ecological framework. In fact, for simplification purposes the previous models were assuming that, in line with a horizontalist approach, commercial banks were providing funds on demand to firms for financing their investments. However, the explicit relations among all the sectors of our economy were not fully exposed. In this chapter Graziani’s endogenous money theory is used and we are developing a Post-Keynesian Stock Flow Consistent (SFC) model to track all the economic relations, both the real and monetary ones. At the same time, the use of a SFC model ensures that “there are no black holes - every flow comes from somewhere and goes somewhere” (Godley W. , 1996) through a rigorous accounting framework, which guarantees a correct and comprehensive integration of all the flows and the stocks of an economy. Such as Kalecki, Graziani and the circuitists economists introduce a preliminary distinction between producers and wage earners. The first step of the monetary circuit is always characterized by firms’ decision to activate production and, in order to do so, they take up loans by commercial banks. In this sense, commercial banks are able to create deposits ex nihilo, granting them loans and, at the same time, creating deposits. In this way, the starting logical cause of the expansion of money is exactly the firms’ willingness of contracting a liability to activate production. In the second step, firms use those loans to pay workers and in this way to obtain the amount of consumption goods desired through the production process. When such funds are transferred by firms to households they instantaneously become income paid for the work provided to firms by workers. Finally, the last step of the Monetary Circuit is characterized by the households’ spending decision to use the money balances previously obtained as income. In this step, while households use their funds to buy consumption goods, firms obtain back those money balances they initially paid to households for their work. In this way, the previous Monetary Circuit analysis is not in contrast with the one made by Kalecki upon the way workers obtain their wages and use all of them to buy consumption goods while capitalists are able to spend just a proportion of their income. Finally, together with its social and monetary framework, our economy is also characterized by an environmental one since we here study the impacts that the economic consumption has in terms of ecological erosion of natural resources. In this way, the model of chapter IV questions the expenditure margins of the Government – in particular after a crisis - and uses the suggestions of the monetary circuit theory to analyse the space for fiscal policies to reduce unemployment boosting the economic activity, to obtain a more equitable distribution between social classes in a sustainable ecological way. Our understanding is that despite many contributions focused on the topics of recovery, distribution and ecological sustainability, few of them tried to tackle them all in a comprehensive way considering the rediscovery of the endogenous money phenomena as one of the most important breakthroughs in the last decades. Here we argue that exactly the endogenous money feature is the essential fil rouge to better understand and connect the three previous important aspects. It is so when we analyse the sectors connections and the policies ones devoted to recovery, and also if we consider how the different incomes and wealth are captured and distributed by the different social classes and finally when we point out the ways of financing long term ecological path to preserve a sustainable environment. Indeed, our overall work in Chapter II, Chapter III and Chapter IV is a step by step construction of an organic and consistent model. It starts with a more theoretical and simplified approach through Chapter II which investigates the (in)stability conditions of the Kaleckian approach while suggesting the presence of an autonomous figure such as the government one. Chapter III adds more real base features through endogenous investments and government presence while Chapter IV finally concludes considering all the real and monetary links of the sectors into a social and ecological framework.

Scopo di questa ricerca è interrogarsi sulla storia del campo di problematizzazione dell'etica professionale e sulle condizioni di possibilità per il darsi di un tale campo, nella convinzione che ciò consenta di riflettere da una prospettiva critica meno usuale sulla rilevanza politica del lavoro, che funge indubbiamente - nella società occidentale contemporanea - da elemento essenziale di inclusione esplicandosi come funzione normata di produzione di identità politico-sociale. Dopo aver reso conto dell'attuale dibattito in materia di etica e deontologia professionale, dei suoi immediati antecedenti e della sua relazione di affinità rispetto al contesto socioeconomico in cui esso matura, l'attenzione si concentra pertanto su una ricostruzione storica del concetto di professione che – ragionando non tanto sul versante weberiano del Beruf quanto su quello latino della professio, con speciale riferimento alla professio census e alla tematizzazione de officiis – muove dal diritto romano e dal pensiero patristico risalendo fino all'esperienza medievale, alla trattatistica della Controriforma e al graduale emergere di un'etica professionale in senso stretto sul finire del Settecento, per provare a chiarire nei termini di “inclusione nell'ordine” quell'intreccio tra radice teologica, politica ed economica che aiuta a comprendere il rilievo che alla professione è stato via via riconosciuto sul piano etico e politico-sociale.

La tesi indaga la logica dell'integrazione europea prendendo in esame il caso dell'Unione Bancaria. Due sono gli argomenti che vengono sostenuti. Il primo é che l'Unione Bancaria é la soluzione imperfetta ad uno spillover funzionale che emerge dalla moneta unica. Il secondo é che l'integrazione europea é un processo di centralizzazione duale i cui fuochi sono le istituzioni sovranazionali e gli stati più potenti. / The dissertation inquiries into the logic of European integration by employing the newly established Banking Union as a case study. Two arguments are developed. First, the Banking Union is the imperfect solution to a functional spillover emerging from the common currency. Second, European integration is best understood as a process of centralisation around supranational institutions and powerful states.

Il presente lavoro intende esaminare il processo di decision making relativo alla politica sociale statunitense sviluppatosi a partire dalla fine degli anni Sessanta, fornendo un’analisi di carattere «istituzionalista» che ponga in rilievo gli snodi cruciali del dibattito relativo al welfare system federale svoltosi sia all’interno del Congresso, sia presso i think tank, i centri universitari, le organizzazioni culturali e religiose, le lobby e le altre realtà associative emerse dalla società civile. In particolare, la ricerca si concentra sull’intreccio tra ideologia politica, mentalità tradizionale, opinione pubblica e interessi specifici, e sull’influsso esercitato dalla dimensione culturale e istituzionale sul processo legislativo. Sono stati individuati quattro principali indirizzi socio-politici, ciascuno dei quali ha avuto un particolare influsso su altrettante ‘fasi’ del processo di riforma del welfare system statunitense svoltosi tra il 1968 e il 2006. L’analisi del dibattito culturale e politico è stata suddivisa pertanto in quattro diversi capitoli (capp. 2-5) che consentono di delineare percorsi distinti per le diverse ipotesi socio-culturali individuate, ai quali viene anteposta una premessa storica relativa alle origini del sistema assistenziale e previdenziale statunitense e alle politiche riformiste degli anni Sessanta (cap. 1). / The dissertation examines the process of decision making that determined the development of U.S. social policy from the end of the Sixties. It analyzes the institutional character of the debate that took place inside the Congress and inside the think tanks, the academic centers, the cultural and religious foundations and other associations. In particular, the research is focused on the tangle between political ideologies, traditional culture, public opinion and legislative process. The dissertation identifies four different socio-political streams: each of them influenced a particular “phase” of the reform of the U.S. welfare system from 1968 up to 2006. The analysis of the cultural and political debate has been divided in four chapters (chapters 2-5) that allow to delineate different developments for the four streams, after an historical premise (chapter 1) that presents the origins of American welfare system, from the colonial times to the Sixties.
