During the past decade, renewable energy sources have become an indispensable pillar in European electricity generation. This paper aims at examining if the increasing importance of renewables stimulates investment in European power transmission networks. The question of interest is addressed by an error correction investment model that builds on Neoclassical theory and is further augmented by recent literary findings. Under the proposed threefold estimation strategy, the share of renewables is not found to significantly influence investment spending when the full set of transmission system operators are considered. However, a slight and justified sample restriction leads to the conclusion that a rising share of renewable energy sources substantially increases investment in power transmission networks. / Series: Department of Economics Working Paper Series

Has economic integration improved the postwar growth performance of the actual fifteen member states of the European Union (EU)? To answer this question, we first construct an index of integration for each member state that explicitly accounts for global integration (GATT) as well as regional (European) integration. Using this variable, we test for permanent and temporary growth effects in a dynamic growth accounting framework, both in a time series setting for the (aggregate) EU and a panel approach for the EU member states. Although the hypothesis of permanent growth effects as postulated by endogenous growth models with scale effects is clearly rejected, we find significant levels effects: GDP per capita of the EU would be approximately one fifth lower today, if no integration had taken place since 1950. Interestingly, two third of this effect are due to GATT-liberalization. (author's abstract) / Series: EI Working Papers / Europainstitut

In this paper we analyse the implications of the euro for the international reserves in the Eurosystem. Two conceptually different effects of the changeover have to be distinguished: a technical effect that largely arises as a matter of accounting, and a behavioural effect that stems from the fact that the optimal demand of the aggregate Eurosystem is not equal to the sum of the optimal country levels. The technical effect arises from two main sources: the abolishment of the ECU-creating mechanism, and the redefinition of international reserves which precludes (former) reserves that were denominated in euro-currencies. As a result the average reserves of the Eurosystem in 1999 amounted to $287 billion, considerably less than in 1998 ($345 billion). We then derive a reserve demand function for the aggregate Eurosystem using panel data estimation techniques and simulate reserve demand for the situation after the regime shift. The optimal aggregate level of reserves turns out to be some $188 billion, which implies excess reserves in the Eurosystem amounting to approximately $100 billion in the year 1999. We go on by proposing a key by which this excess could be allocated to the individual countries taking the asymmetric distribution of reserves in the Eurosystem into account. Finally we classify and enumerate the proposals for making use of the estimated reserve overhang. (author's abstract) / Series: EI Working Papers / Europainstitut

We analyze empirically the role played by energy inflation as a determinant of downward corrections in house prices. Using a dataset for 18 OECD economies spanning the last four decades, we identify periods of downward house price adjustment and estimate conditional logit models to measure the effect of energy inflation on the probability of these house price corrections after controlling for other relevant macroeconomic variables. Our results give strong evidence that increases in energy price inflation raise the probability of such corrective periods taking place. This phenomenon could be explained by various channels: through the adverse effects of energy prices on economic activity and income reducing the demand for housing; through the particular impact on construction and operation costs and their effects on the supply and demand of housing; through the reaction of monetary policy on inflation withdrawing liquidity and further reducing demand; through improving attractiveness of commodity versus housing investment on asset markets; or through a lagging impact of common factors on both variables, such as economic growth. Our results contribute to the understanding of the pass-through of oil price shocks to financial markets and imply that energy price inflation should serve as a leading indicator for the analysis of macro-financial risks.

Spillover phenomena are usually statistically estimated on the basis of regional and temporal panel data. In this paper we review and investigate exploratory and confirmatory statistical panel data techniques. We illustrate the methods by calculations in the stetting of the well known Research and Development Spillover study by Coe and Helpman (1995). It will be demonstrated that alternative estimation techniques that are well compatible with the data can lead to opposite conclusions.

This paper uses data for 255 NUTS-2 European regions over the period 1995-2003 to test the relative explanatory performance of two important rival theories seeking to explain variations in the level of economic development across regions, namely the neoclassical model originating from the work of Solow (1956) and the so-called Wage Equation, which is one of a set of simultaneous equations consistent with the short-run equilibrium of new economic geography (NEG) theory, as described by Fujita, Krugman and Venables (1999). The rivals are non-nested, so that testing is accomplished both by fitting the reduced form models individually and by simply combining the two rivals to create a composite model in an attempt to identify the dominant theory. We use different estimators for the resulting panel data model to account variously for interregional heterogeneity, endogeneity, and temporal and spatial dependence, including maximum likelihood with and without fixed effects, two stage least squares and feasible generalised spatial two stage least squares plus GMM; also most of these models embody a spatial autoregressive error process. These show that the estimated NEG model parameters correspond to theoretical expectation, whereas the parameter estimates derived from the neoclassical model reduced form are sometimes insignificant or take on counterintuitive signs. This casts doubt on the appropriateness of neoclassical theory as a basis for explaining cross-regional variation in economic development in Europe, whereas NEG theory seems to hold in the face of competition from its rival.

El Plan Nacer es un programa del Ministerio de Salud de la Nación Argentina que invierte recursos con el objetivo de mejorar la cobertura y calidad de los servicios de salud en niños menores de seis años, mujeres embarazadas y puérperas que no poseen obra social. La novedad del mismo radica en la generación de un seguro público de salud para la población materno-infantil sin cobertura social y en la aplicación de un modelo de financiamiento basado en resultados. Este trabajo investiga los efectos del Plan Nacer sobre la mortalidad infantil en la Argentina siguiendo un enfoque no-experimental, basándose particularmente en la metodología de diferencias en diferencias, que consiste en la comparación de condiciones sanitarias entre poblaciones inscriptas y no inscriptas al programa, antes y después de su implementación. La fuente principal de variación es la participación en el programa a nivel departamental. El análisis de impacto realizado considera el caso de un tratamiento en donde las unidades bajo programa están sujetas a distintos grados de exposición al mismo. Los resultados encontrados indican que el Plan Nacer genera una reducción de la tasa de mortalidad infantil. El resultado es ambiguo si se divide a la tasa de mortalidad infantil entre la tasa de mortalidad neonatal, y la tasa de mortalidad post-neonatal: mientras que el Plan tiene un impacto negativo sobre la segunda, no ocurre lo mismo con la primera. Además no parecería existir un efecto del programa sobre la tasa de mortalidad materna.

This paper empirically investigates the propagation of business sentiment within the European Union (EU) and adds to the literature on shock absorption via a common market's real economy. To this end, we combine EU-wide official business sentiment indicators with world input-output (IO) data and information on indirect wage costs. Econometrically, we model interdependencies in economic activities via IO-linkages and apply space-time models. The resulting evidence provides indication for the existence of substantial spillovers in business sentiment formation. Accordingly, and highlighted by the estimated impacts of changes in indirect labor costs, policy reforms aiming at increasing the resilience of the European single market need to take these spillovers into account in order to increase its effectiveness. / Series: Department of Economics Working Paper Series

Several studies suggest that the introduction of the Euro has triggered sizeable increases in intra-Euro area trade. In this paper we test whether these gains are distributed asymmetrically among Euro area countries with respect to country size. This hypothesis is motivated by Casella (1996), who postulates that small countries of a trade bloc gain more from its enlargement. We argue that the implications of this model do also apply to the introduction of a common currency and test for a small country bonus using aggregate trade data and disaggregated trade data at the SITC1, SITC2, and SITC3 level. The results suggest that there is indeed strong evidence for a small country bonus with respect to the gains from trade after the introduction of the Euro. On average, the Euro triggered a reallocation of intra-Euro area exports to small countries by some 6 percent. / Series: EI Working Papers / Europainstitut

This paper evaluates the monetary and macroprudential policies that mitigate the procyclicality arising from the interlinkages between current account deficits and financial vulnerabilities. We develop a two-country dynamic stochastic general equilibrium (DSGE) model with heterogeneous households and collateralised debt. The model predicts that external shocks are important in driving current account deficits that are coupled with run-ups in house prices and household debt. In this context, optimal policy features an interest-rate response to credit and a LTV ratio that countercyclically responds to house price dynamics. By allowing an interest-rate response to changes in financial variables, the monetary policy authority improves social welfare, because of the large welfare gains accrued to the Savers. The additional use of a countercyclical LTV ratio that responds to house prices, increases the ability of borrowers to smooth consumption over the cycle and is Pareto improving. Domestic and foreign shocks account for a similar fraction of the welfare gains delivered by such a policy. (authors' abstract)
