The purpose of this paper is to investigate the determinants of aggregate suicides in 15 OECD countries during 1960-2010 using an economic model where changes in the welfare of consumers play the critical role for determining the number of suicides.

The hardship index based on economic theory is developed. In estimating the model, the authors apply the Pesaran et al. (2001) approach that allows the simultaneous estimation of the long-run and short-run parameters. To make sure that the authors’ findings are not specific to their method, the authors also use the generalized method of moments estimation in the panel set-up.

The authors found a relatively strong positive relationship between macroeconomic conditions, especially changes in aggregate consumption, and suicides. The relationship appears to be robust also in terms of the various control variables cited in the literature. The hardship index which is based on the habit persistence model of consumption predicts and explains the long-term behavior of suicides in most of the countries. Thus, the hardship index is a better economic explanatory variable than the unemployment rate or other proxies describing economic conditions.

Marrying the economic theory and econometric methods produces a reasonable empirical model to explain the connection between aggregate economic conditions and suicides.

The purpose of this paper is to contribute to the teaching of undergraduate macroeconomics.

To suggest a roadmap, based on a consumption function, to be used by instructors willing to teach the Lucas Critique subject.

Therefore, this paper proposes a lesson, which consists of three parts, to help undergraduates better understand the subject: (1) a grading exercise to bring the topic closer to students’ lives; (2) a Keynesian and an optimal consumption function, followed by an example based on an unemployment insurance policy; and (3) two optional topics consisting of extensions of the optimal consumption function and some empirical results related to the Lucas Critique.

The Lucas Critique influenced the evolution of research in macroeconomics, but it is not easily grasped in a classroom.

The present study aims to evaluate the aggregate consumption function from the perspective of the Euler equation using Indian macroeconomic data. Further, to examine the robustness of the findings for India, other developing nations are also studied.

Quarterly time-series data from 1996:1 to 2020:3 on consumption and income in India are used to evaluate the alternative model proposed by Campbell and Mankiw (1989). The alternative hypotheses in the present study are tested by estimating models using the instrumental variable approach. The lagged changes in the quarterly average of 91-day Treasury bill yields are used as the nominal interest rate instrumental variables along with other lagged instrumental variables.

The evidence presented in this study suggests that aggregate consumption is better explained when the permanent income model incorporates rule-of-thumb consumers, that is, individuals who consume their current income along with those who consume their permanent income.

The new rule-of-thumb framework better explains some of the observed phenomena, such as why the expected changes in consumption are related to the expected changes in income, why the expected changes in consumption are unrelated to real interest rates (i.e. why the intertemporal elasticity of substitution is near zero) and why a high consumption/income ratio is usually followed by an increase in income growth.

This study adds to the limited literature on the Euler-based consumption function in developing economies.

This paper seeks to measure and characterise the extent of consumer over‐indebtedness among the European Union (EU) member states.

The study evaluates alternative measures of over‐indebtedness on the basis of the permanent‐income/life‐cycle theories of consumption behaviour and adopts a subjective approach in identifying over‐indebted households on the basis of European household survey data. It then investigates the main characteristics of over‐indebted households.

The empirical results reveal that over‐indebtedness was a significant problem across EU member states in the mid‐1990s. Moreover, an inverse relationship emerged between the extent of the over‐indebtedness problem and the extent of consumer borrowing across EU countries.

Anecdotal evidence seemed to suggest that some main factors behind over‐indebtedness could be “market failure” on the credit market, the existence of liquidity constraints and lack of access to formal credit markets. However, a comprehensive and rigorous investigation of the extent and determinants of over‐indebtedness can only be achieved through analysis of more extended household data sets, particularly panel data.

The EU credit markets exhibited certain symptoms of “market failure”, on the one hand, and there was also need for further financial liberalisation in the Southern European countries, on the other hand.

The paper provides a first systematic evaluation of existing measures of consumer over‐indebtedness as well as the first EU‐wide empirical investigation of the problem. It should provide valuable information to the credit industry as well as financial regulatory bodies.

This study aims to examine the consumption behaviour in Organization of Islamic Cooperation countries.

Using time series and panel data, this study estimates rational expectations permanent income hypothesis model and the intertemporal elasticity of substitution, and examines the response in consumption to expected and unexpected changes in income.

The evidence supports the phenomenon of loss aversion. The response of consumption to unexpected income changes is statistically significant in only one-third of the countries in the sample. Conversely, the response of consumption to expected income changes is statistically as well as economically significant in one-fourth of the countries in the sample. The intertemporal elasticity of substitution is also statistically insignificant in majority of OIC countries in the sample.

The evidence in support of loss aversion in preferences could help in explaining the low penetration of equity-based risk sharing instruments in Islamic finance.

The excess sensitivity of consumption to income suggests that redistribution efforts to enhance incomes of poor households could help in enhancing their consumption levels.

The study takes a comprehensive sample across time and space for OIC countries as compared to previous studies and also adjusts the budget constraint for Zakat.

Until now, traditional western consumption theories have not been able to adequately explain the consumption behavior of Chinese residents in the economic transitional period. Based on annual data from 1986 to 2004, the purpose of this paper is to examine the excess sensitivity of consumption through a variable parameter model.

A regression model was used to analyse annual consumption data from 1986 to 2004 in China.

The analysis demonstrates excess sensitivity characteristic in Chinese residents' consumption in the economic transitional period.

The paper concludes that in order to make the demand stimulation policy in China more effective, it is necessary to take a series of measures to correct the excess sensitivity of consumption, so as to establish a healthy cycle of national economy. The paper has only explained excess sensitivity of Chinese residents' consumption from the point of view of economics. While consumption is an economic problem as well as a social problem, those factors beyond economics should not be excluded from the analysis.

This paper differs from former studies in that previous scholars failed to take into consideration the special economic characteristics in China's transitional economy. The variable parameter model this paper employed takes full consideration of such unique factors as economic expectations and systems changes during the transitional period so as to better explain Chinese people's consumption behavior and provide a new perspective to make government policies stimulate domestic demand more effectively.

This paper explores the role of Zakah in social cause marketing. Academic literature on Islamic economics, finance and management mostly deals with the links that exists between Zakah and consumption, neglecting important and strategic links with social cause marketing. This paper emanated from need to outline social cause and the charitable role of Zakah in promoting Halal businesses, poverty alleviation and sustainable development. Most works in the field of Zakah did not foresee the role of marketing. This is a misjudgement, as this work showed that Zakah yields large and measurable social gains to help the society and a firm.

Secondary sources were used in writing this paper. Available literature in the form of journals, books, manuals and reports was referred to. As a conceptual work, the paper does not test hypothesis or pretends to provide empirical evidences. It uses mathematical economics in arriving at some of the conclusions. Findings were derived through deductions and critical discourses, not through crunching of primary data.

The paper shows how Zakah, Halal consumption and corporate social responsibility are connected and highlights the role of Zakah as a social marketing tool. It shows how Zakah affects consumption through marginal propensity of Zakah recipients who spend Zakah money on basic needs.

The paper looks at the broad aspects of Zakah and social marketing. How to make Zakah a pillar of Islamic firms’ social cause programs shall be the focus of future academic works in this area.

The paper is unique in drawing attention of Islamic firms to the effectiveness of Zakah in building a corporate image. It draws the attention of firms, activists, academics and governments to functions of Zakah that have not been studied in depth.

The paper aims to examine the consumption behavior of Chinese residents during economic transition. It explores whether Western theories of consumption are applicable to the Chinese situation, and then tests the hypothesis based on Chinese traditional culture and dynamic nature of system change.

The paper opted for an empirical‐based approach. A regression model was used to analyze annual consumption data from 1986 to 2008 in China.

The paper provides empirical insights and suggests that under the influence of Chinese traditional culture and dynamic change of the Chinese economic system, Chinese urban residents exhibit a special consumption pattern of an intermittent and cyclical nature.

The paper concludes that in order to make the consumption stimulation policy in China more effective, it is necessary to establish a series of measures such as establishing a sound social welfare system as well as narrowing the gap between the rich and the poor, which will substantially increase the buying power of the less‐privileged groups and thus will increase the overall spending in the society. Although the econometric model used in this paper is adequate, a different approach like time series econometrics may give us additional insights. Researchers are encouraged to test the hypothesis further by employing other methodologies. Second, due to the lack of its own theories in the emerging market, this study remains exploratory.

This paper fulfils an identified need to study the special consumption behavior of Chinese urban residents during the economic transition.

Institutions, social norms and the nature of industrial relations vary greatly between Latin American and Western European countries. Such institutional and organizational differences might shape firms’ operational environment in general and the type of competition in product and labor markets in particular. The purpose of this paper is to identify and quantify industry differences in product and labor market imperfections in Chile and France.

The authors rely on two extensions of Hall’s econometric framework for estimating price-cost margins by nesting three labor market settings (LMS) (perfect competition (PC) or right-to-manage bargaining, efficient bargaining (EB) and monopsony). Using an unbalanced panel of 1,737 firms over the period 1996-2003 in Chile and 14,270 firms over the period 1994-2001 in France, the authors first classify 20 comparable manufacturing industries in six distinct regimes that differ in the type of competition prevailing in product and labor markets. The authors then investigate industry differences in the estimated product and labor market imperfection parameters.

Consistent with differences in institutions and in the industrial relations system in the two countries, the authors find regime differences across the two countries and cross-country differences in the levels of product and labor market imperfection parameters within regimes.

This study is the first to compare the type and the degree of industry-level product and labor market imperfections inferred from consistent estimation of firm-level production functions in a Latin American and a Western European country. Using firm-level output price indices, the microeconomic production function estimates for Chile are not subject to the omitted output price bias, as is often a major drawback in microeconometric studies of firm behavior.

An overview of the cointegration approach to econometric specification and estimation is provided. A non‐technical approach is adopted, and is intended to serve as an entry into this important new literature for the reader with no background knowledge of the subject but with some limited knowledge of econometrics. Particular emphases are given to the rationale for using cointegration techniques in the estimation of economic relationships, to providing intuitive explanations of the concepts and techniques, and to demonstrating their applications in practice. Reference is made throughout to other articles which explain particular methods or recent developments more formally and fully than is possible here. Finally, a simple application of cointegration techniques to the estimation of the consumption function is provided.
