Robust estimation of models of Engel curves

Both standard and robust methods are used here to estimate models of Engel curves for three household commodities, namely, food, transport, and tobacco and alcohol in Canada. The income elasticities of demand computed from the various methods differ significantly for the transport and tobacco-alcohol consumption where there are obvious outliers and zero expenditures problem. Robust estimators point to lower income elasticities and have better performance than the standard LS and Tobit estimator. These results are analyzed in the light of the information on finite-sample performance obtained in a previous Monte Carlo study.

The impact of cross-border acquisitions on target banks’ performance in an institutionally poor environment: Ukraine’s takeover wave

We investigate the impact of the 2005–2007 cross-border bank takeovers in Ukraine – a country with poor institutional quality – on the performance of the target banks. Because acquirers targeted mainly larger, less-capitalised banks, we control for selection bias by combining propensity score matching and a difference-in-difference methodology. We find that the cost efficiency of the acquired banks improved after takeover (because of a decreased reliance on deposits), but that neither their profitability nor their loan market shares increased. Overall, our findings tally only piecemeal with the existing multi-country studies for transition economies. This argues in favour of additional single-country research.     

ENVY, INSTITUTIONS AND GROWTH

The use of interdependent preferences provides an intuitive link between institutions and growth. Envious agents that care about relative wealth choose to use an available destruction technology to inflict harm on the wealth of other agents when institutions fail to make property rights secure, while they use a production technology to increase their wealth when institutions make it easy and hassle-free to engage in production. The use of interdependent preferences is justified by an extensive literature and can provide a motive for agents to take actions that block growth in the absence of theft or other concrete gains.     

Institutions Rule: The Primacy of Institutions Over Geography and Integration in Economic Development

We estimate the respective contributions of institutions, geography, and trade in determining income levels around the world, using recently developed instrumental variables for institutions and trade. Our results indicate that the quality of institutions trumps everything else. Once institutions are controlled for, conventional measures of geography have at best weak direct effects on incomes, although they have a strong indirect effect by influencing the quality of institutions. Similarly, once institutions are controlled for, trade is almost always insignificant, and often enters the income equation with the wrong (i.e., negative) sign. We relate our results to recent literature, and where differences exist, trace their origins to choices on samples, specification, and instrumentation.     

Does economic growth benefit the poor? The role of institutions and religions

This paper seeks to explain the difference across countries of the impact of national growth on the growth of the income of the poor. Traditionally, studies attempting to explain such differences investigate only the impact of some additional variables on the income level of the poor. Here, we introduce interaction terms to explain the change in the elasticity of income of the poor to national income. We focus on the role of formal and informal institutions and religions; variables which have rarely been considered in this context. The results show that only formal institutions (i.e., Resistance to corruption) and, to some extent, informal institutions (i.e., Trust all) explain the differences. Religion has no impact. The findings also show that improvements in the Resistance to corruption benefits the extremely poor more than the poor.     

Immigration and economic growth: do origin and destination matter?

This article assesses the heterogeneous effects of immigration on economic growth depending on both the origin and the destination countries. Following the development of a growth model augmented by human capital of immigrants, we estimate it in a dynamic panel setup using the system-GMM estimator. We find that the growth-enhancing effect of immigration is significantly larger when immigration flows from developed to developing economies than when it does to those that include both developed and developing economies. We interpret these results as evidence of immigrants from developed countries bringing with them their advanced knowledge into the developing countries.     

Institutions and the financial development–economic growth nexus in sub-Saharan Africa

Using a sample splitting approach that does not impose an exogenous quadratic term, we examine the effect of financial development on economic growth in sub-Saharan Africa by allowing the link to be mediated by the level of institutions. Our findings reveal a disproportionate growth-enhancing effect of finance, given countries’ distinct level of institutional quality. More specifically, when the International Country Risk Guide-based measure of institutions is used as the threshold variable, below the optimal level of institutional quality, financial development does not significantly promote economic growth. For countries with institutional quality above the threshold, higher finance is associated with growth. However, when institutions are measured by World Governance Indicators proxy, we find a significant effect of financial development, irrespective of whether a country is below or above the threshold. Interestingly, the growth-enhancing effect of finance is greater for low-institution countries relative to high-institution countries. Thus, through its ability to provide some crucial roles, the well-developed financial sector may also perform the function of sound institutions in influencing economic growth.     

Parametric and Semi-Nonparametric Estimation of Willingness-to-Pay in the Dichotomous Choice Contingent Valuation Framework

Standard procedures for extractingwillingness-to-pay (WTP) from dichotomouschoice CV questionnaires rely heavily uponparametric assumptions regarding thedistribution and form of WTP in the sampledpopulation. However, theory provides littleguidance regarding which parametricspecification to use and the resulting WTPestimates can be sensitive to the selectionsmade. Here we compare and contrast severalparametric and semi-nonparametric estimatorsthat have been proposed in the literature,examining the sensitivity of the resulting WTPestimates to the underlying distribution ofpreferences and the estimation procedureemployed.     

Determinants of long-term growth: New results applying robust estimation and extreme bounds analysis

Two important problems exist in cross-country growth studies: outliers and model uncertainty. Employing Sala-i-Martin’s (1997a,b) data set, we first use robust estimation and analyze to what extent outliers influence OLS regressions. We then use both OLS and robust estimation techniques in applying the Extreme Bounds Analysis (EBA) to deal with the problem of model uncertainty. We find that the use of robust estimation affects the list of variables that are significant determinants of economic growth. Also the magnitude of the impact of these variables differs sometimes under the various approaches.First version received: March 2003 / Final version received: June 2004We like to thank two referees for their very helpful comments on a previous version of this paper.

Homogeneous,heterogeneous or shrinkage estimators? Some empirical evidence from French regional gasoline consumption

This paper contrasts the performance of heterogeneous and shrinkage estimators versus the more traditional homogeneous panel data estimators. The analysis utilizes a panel data set from 21 French regions over the period 1973–1998 and a dynamic demand specification to study the gasoline demand in France. Out-of-sample forecast performance as well as the plausibility of the various estimators are contrasted.The authors would like to thank Jean-Loup Madre, Research Director at INRETS, for his assistance with obtaining the data set and the editor Robert M. Kunst and two referees for their helpful comments and suggestions. Badi H. Baltagi would like to thank the Bush Program in Economics of Public Policy for its support.

What are the Policy Lessons from Sweden? On the Rise,Fall and Revival of a Capitalist Welfare State

This paper discusses a number of questions with regard to Sweden's economic and political development:

? How did Sweden become rich?

? What explains Sweden's high level of income equality?

? What were the causes of Sweden's problems from 1970 to 1995?

? How is it possible that Sweden, since the crisis of the early 1990s, is growing faster than most EU countries despite its high taxes and generous welfare state?

These questions are analysed using recent insights from institutional economics, as well as studies of inequality and economic growth. The main conclusion is that there is little, if any, Swedish exceptionalism: Sweden became rich because of well-functioning capitalist institutions, and inequality was low before the expansion of the welfare state. The recent favourable growth record of Sweden, including the period of financial stress (2008–10), is a likely outcome of a number of far-reaching structural reforms implemented in the 1980s and 1990s.
