The theme of this dissertation is Ricardian equivalence, and its objective is to examine the effects of government debt on private consumption expenditures (Essay One), on interest rates (Essay Two), on the current account balance (Essay Three), and on individual intertemporal decision-making (Essay Four). The effects of government debt are important if debt is neutral (e.g., if “Ricardian equivalence” holds), then a stabilization program that is based on demand management policy to curtail fiscal deficits will not be operative. On the other hand, if debt is not neutral (or if Ricardian equivalence does not hold), then deficit finance may induce private consumption, boost interest rates, crowd out investment, and retard economic growth. Essay One contributes to the existing literature by taking into account the nature of liquidity constraints in a developing economy in an aggregate consumption function. Previous empirical tests on Ricardian equivalence have not considered the role of a dominant resource aspect of a country. Essay Two and Essay Three incorporate a dominant resource aspect in Indonesia by estimating the oil-macroeconomic relationship. Furthermore, Essay Three takes into account the role of capital inflows by including debt securities. Essay Four uses experimental economics methods to examine the role of distortionary taxes on Ricardian equivalence. There have been only a few studies that use an experimental approach to examine the effect of deficit spending on consumption expenditures, but these existing experimental studies ignore the role of distortionary taxes in affecting subjects’ consumption-saving decisions and focus on the presence of liquidity constraints, myopia, and uncertainty on future income. Essay Four contributes to the Ricardian equivalence literature by taking into account distortionary taxes in a Ricardian institution by levying taxes on savings in an intertemporal individual consumption-savings decision in laboratory experiments. By utilizing the aggregate consumption function and the Euler equation consumption function, Essay One shows that Indonesian consumers tend to behave in a non-Ricardian way. Public debt most likely will lead to crowding out of investment, and will retard capital accumulation and economic growth. The extent to which individuals perceive government expenditures as complements for their consumption is substantial. An increase in government expenditures will increase the marginal utility of private consumption and has an expansionary effect on aggregate demand. The complementarity between private consumption and government expenditures may be partly due to the allocation of government subsidies to basic goods and services such as electricity, fuel, fertilizer, health centers, and education. Liquidity constraints may cause consumption to have an excess sensitivity to income. The short-run and long-run aggregate consumption function estimates show that income affects consumption, indicating that consumers follow a “rule of thumb” of consuming their current income. A high ratio of public debt to gross domestic product (GDP) in Indonesia may also be the culprit of the excess sensitivity of private consumption to income. Due to low salaries in the formal sector, employees have been engaged in moonlighting activities, mostly in the form of self-employment (e.g., opening retail stores or services). This phenomenon may help to explain why private credit−which amounts to 29 percent of GDP−fails to explain consumption behavior. Most loans are made for investment rather than for consumption. Consumers’ behavior is insensitive to taxation, which perhaps is due to the fact that tax enactment is not explicitly revealed in Indonesia (e.g., price tags in the supermarket include the sales tax, and employees are only informed about their after-tax net wage instead of their gross wage). The share of tax collections to GDP averages only about 15 percent. There is still a large portion of the population who do not pay taxes or who pay far below what they should pay. The fiscal authority needs to focus more attention on alternative financing, i.e. taxation, whose system is essential to be enhanced. Essay Two shows that by excluding oil prices, deficits and debt significantly increase the real interest rate, thereby invalidating Ricardian equivalence. The evidence shows some preference for debt and deficit over government expenditures as determinants of interest rates. Inclusion of the oil price weakens the Neoclassical results, providing more support for the Ricardian paradigm. Deficits no longer increase interest rates, yet debt still significantly increases interest rates. This result reflects a loss of momentum for the Indonesian government two decades ago to decrease its dependency on debt. The government could have used the windfall oil revenue to pay off foreign debt; instead, the windfall was spent on import-intensive infrastructure development projects, in order to build domestic industry and to subsidize rice and petroleum products. The importance of oil prices in the interest rate estimation suggests that in modeling the Indonesian macroeconomy, the oil sector should be incorporated. The non-stationary nature of the stock of debt implies the failure of intertemporal budget balance to hold, indicating that the debt-financed deficit is unsustainable. Essay Three shows that around 80 percent of the estimation results provide support for the Neoclassical view, a result that is consistent with the twin deficits hypothesis. The long-run estimates indicate an almost one-to-one relationship between the government budget and the trade balance, while the short-run estimates show a smaller magnitude. When capital inflows are included, the twin deficits phenomenon is less pronounced in the short-run and disappears in the long-run. An increase in the oil price statistically and significantly improves the trade balance in the short-run and in the long-run. Essay Four shows that subjects fully anticipate an increase in future taxation by increasing the amount bequeathed in one-to-one correspondence to the increase in debt. Even under a Ricardian institution, the distorting nature of taxes on savings alters subjects’ consumption-savings decisions. The equality of the change in bequests and the change in deficit spending is not attained under the savings taxes treatment, invalidating Ricardian equivalence. In line with the results of Essays One, Two, and Three, which suggest the vital need to enhance the taxation system, the results of Essay Four entail the importance of taxes on interest income in Indonesia.

The purpose of this thesis is to explore the possibilities and advantages of describing macroeconomic relationships with a certain well-defined class of parametric nonlinear econometric models, called smooth transition regressions (STR). An STR model is a flexible nonlinear specification with a continuum of regimes. It is locally linear transitions from one extreme regime to another are determined by a function of a continuous variable, the transition variable.The thesis consists of four essays and the macroeconomic relationships that are considered are: Consumption, Money Demand and the Phillips Curve. The essays of this dissertation emphasise the importance of allowing for a flexible functional form when dealing with macroeconomic relationships. / Diss. Stockholm : Handelshögsk.

First, this paper presents basic definitions of the consumption function and gives a summary of main theoretical concepts of consumption as well as an overview and discussion of important papers on consumption. Above all, papers examining the influence of the interest rate upon consumption are accented. Furthermore it contains a brief context summary of current and potential eurozone members, work of the ECB and execution of common monetary policy. Subsequently we discuss the hypothesis of a possibly asymmetric impact of the interest rate upon consumption in individual countries, expand and justify the hypothesis based on indebtedness, wealth, etc. Empirically, hypotheses are tested on historical data of individual countries: transmission between interest rates of central banks (later the ECB) and market interest rates, correlation analysis of consumption changes and central interest rates in individual countries, correlations with year-on-year changes. Also, consumption functions are estimated using time series models while testing alternative variables in the regression equations. We discuss analysis results and methods used; the influence of the interest rate upon consumption seems to be small and the relationship type is not much different across the eurozone countries. Eventually, we outline possible implications of our results with respect to the future of the eurozone and related activity of the ECB.

This thesis addresses a long-standing puzzle in empirical econometrics: Does the size distribution of income matter in the aggregate consumption function? Current opinion on whether distribution matters is divided. There is also a lack of consensus (among those who believe distribution effects exist) on the nature of such effects; that is, whether a decrease or an increase in income inequality is needed to stimulate aggregate demand. In this thesis, the previous or existing tests are challenged on the grounds that they do not properly take into account the causal link between the variability of the marginal, not the average, propensity to consume (with respect to the income level) and the existence of distribution effects. This particular link is taken care of, however, if one tests for the linearity (in income) of the micro relation underlying one's aggregate consumption function. The rejection of the linearity hypothesis will establish the existence of distribution effects. Ex post, if the nonlinear relation is such that the marginal propensity to consume declines with income, it also follows that an equalization in the income distribution produces greater aggregate consumption. The theoretical contribution of this thesis lies in the clarification of these issues. On the empirical side, this thesis cautions against the casual use of the term "distribution effects". In the current income-current expenditure framework of the Keynesians, it refers to "the effect of a redistribution of real disposable income" on aggregate real consumers' expenditure. In the Permanent Income Hypothesis framework, however, it could mean either "the effect of a redistribution of real disposable income" or "the effect of a redistribution of real permanent income" on aggregate real consumption. In this thesis, the distributions of real disposable income and real permanent income are alternatively assumed to follow the lognormal density, and two conclusions are empirically determined: I. The distribution of real disposable income matters in the current income-current expenditure framework---this result is statistically significant at a 10% level after the correction for serial correlation and simultaneity bias. In particular, the estimates indicate that the marginal propensity to consume declines with the level of real disposable income and, hence, a decrease in inequality would stimulate aggregate demand. II. The elasticity of consumption out of real permanent income is unity; therefore, the distribution of real permanent income does not matter in the Permanent Income Hypothesis framework---this result is statistically. significant at all conventional levels of significance both before and after the correction for serial correlation. Both findings are based on aggregative time-series data for Canada. The consumer unit in this thesis is an individual income-recipient, and the data period is 1947-1976. Maximum-likelihood procedures have been used in the estimation, with proper allowance for across-parameter constraints. In the event of correction for serial correlation, the autocorrelation coefficient is constrained to the open-interval (+1,-1). The results are also double-checked by examining many avenues that might affect the nature of the outcomes. Another contribution of this study is the compilation of data on the distribution of pre-tax personal income (in current dollars) in Canada under the lognormality hypothesis. The parameters of this distribution are determined using the minimum chi-square method. Estimates of the variance (of logarithms of income) parameter show a slight increase in income inequality over the period 1946 to 1976. The data on this parameter are used to approximate the variance of logarithms for the distribution of real disposable income (while establishing result I) and also the same for the distribution of real permanent income (while establishing the result II). / Thesis / Doctor of Philosophy (PhD)

The goal of this thesis will be to formulate an economic model that exposes the relationship between consumption of luxury goods and selected factors which includes advertising, disposable income, interest rate, price index and stock premium. By building the Multiple Linear Regressions model to formulate the consumption function and using the Ordinary Least Squares (OLS) as the method, it becomes apparent that advertising, disposable income and the previous quarter´s disposable income are the major variables to affect luxury good consumption, of all the factors. Furthermore, the previous quarter´s disposable income has a slightly higher effect than the current one on luxury consumption. Similar studies, which focus on luxury items, have proposed models that test a single or a few variables at a time, and others that concentrate on durable goods have a wide range of variables to examine. I attempt to combine both in my model to test luxury consumption with a wide range of variables. / 1.Abstrsact: short (1/2 page)The very specific purpose of your studyThe finding ( results) The method: statistical method, the data , the theoretical data,Compare your results with the results from similar studies.2.Introduction (1 and half page)A general idea ( 4-6 lines)Make references to theoretical and empirical research paper.Names, dates, and contribution.The purpose of your studyMethodLimitationOutline of the paper3.Conclusion (1 page)The purpose of the studyThe resultsThe methodComparison with the results from similar studiesCritical discussion of your own studiesFurther studies4. consider opponents points too

Tiden före den senaste finanskrisen präglades av generös kreditgivning och ökande inkomstskillnader. Det är väl bevisat att hög skuldsättning ökar risken för finansiell instabilitet, och bevisen blir fler för att inkomstojämlikhet påverkar överskuldsättning i en positiv riktning. Flera, däribland Frank et. al. (2010), vill förklara sambandet mellan inkomstojämlikhet och skuldsättning med att människor ägnar sig åt statuskonsumtion. Frank et. al. (2010) formulerar en hypotes för att empiriskt undersöka huruvida konsumtionsfunktionen bör innehålla en relativ faktor, och syftet för denna uppsats är att undersöka giltigheten i ”hypotesen om utgiftskaskader” i en svensk kontext. Hypotesen testas genom regression av förändringen i andelen skuldsatta hos Kronofogdemyndigheten på förändringen i gini-koefficienten inom kommuner mellan åren 2011-2016. Studien finner inget signifikant samband mellan andelen skuldsatta och gini-koefficientens förändring. Resultatet kan möjligen förklaras med att den geografiska enheten som observeras är för stor. / The years leading up to the latest financial crisis were characterized by generous credit markets and growing income inequality. It is well proven that high indebtedness increases the risk of financial instability, and there is growing evidence of income inequality affecting the debt-rate in a positive direction. Several, including Frank et. al. (2010), believes that the relationship between indebtedness and income inequality can be explained by people engaging in status-seeking consumption. Frank et. al. (2010) formulates a hypothesis to empirically investigate whether the consumption function should contain a relative factor, and the purpose of this paper is to test the validity of the expenditure cascade-hypothesis in a Swedish context.  The hypothesis is tested by regressing the change in the number of people with debt registered at the Swedish Enforcement Authority on the changes in the gini-coefficient within municipalities in the years 2011-2016. The study finds no significant correlation between the number of debtors and the change in the gini-coefficient. The results may be explained by the fact that the geographical unit of observation is too large.

Consumer function is a standard instrument of quantitative economic analysis to examine the relationship between consumer expenditure and income or other influencing factors such as liquid assets, interest rates or various demographic and social factors. In this thesis are presented the most frequently used methods in econometric analysis of consumption function. Attention is paid to the hypothesis of absolute income, relative income, life cycle, permanent income, rational expectations and consumption function based on the error correction model. Furthermore, the suitability of individual models for the current economic situation in the Czech Republic is assessed. Subsequently an empirical model of consumption function for the Czech Republic is designed and tested. Furthermore, the estimates of each consumption function model for the period before and after economic crisis of 2008-2009 are performed and compared. Finally, a short-term prediction of the consumption of Czech households is made.
