Do consumers benefit from quantity discounts?

A monopoly selling to identical consumers gains at their expense if non-linear pricing is permitted. In contrast, under duopoly non-linear pricing may benefit consumers and lower equilibrium profit.     

Does institutional quality resolve the Lucas Paradox?

The Lucas Paradox observes that capital flows predominantly to relatively rich countries, contradicting the neoclassical prediction that it should flow to poorer capital-scarce countries. In an influential study, Alfaro, Kalemli-Ozcan, and Volosovych (AKV) argue that cross-country variation in institutional quality can fully explain the Paradox, contending that if institutional quality is included in regression models explaining international capital inflows, a country’s level of economic development is no longer statistically significant. We replicate AKV’s results using their cross-sectional IFS capital flow data. Motivated by the importance of conducting inference in statistically adequate models, we focus on misspecification testing of alternative functional forms of their empirical model of capital flows. We show that their resolution of the Paradox relies on inference in a misspecified model. In models that do not fail basic misspecification tests, even though institutional quality is a significant determinant of capital inflows, a country’s level of economic development also remains a significant predictor. The same conclusions are reached using an extended dataset covering more recent IFS international capital flow data, first-differenced capital stock data and additional controls.     

Do standards improve the quality of traded products?

We examine whether standards raise the quality of traded products. Matching a panel of French firm–product–destination export data with a data set on sanitary and phytosanitary measures and technical barriers to trade, we find that such quality standards enforced on products by destination countries: (i) favour the export probability of high-quality firms provided that their productivity is high enough, (ii) raise the export sales of high-productivity, high-quality firms at the expense of low-productivity and low-quality firms and (iii) increase the quality supplied by firms if their productivity is high enough. We then develop a simple new trade model under uncertainty about product quality in which heterogeneous firms can strategically invest in quality signalling to rationalize these empirical results on quality and selection effects.     

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.     

Does globalization affect growth? Evidence from a new index of globalization

The study develops an index of globalization covering its three main dimensions: economic integration, social integration, and political integration. Using panel data for 123 countries in 1970–2000 it is analysed empirically whether the overall index of globalization as well as sub-indexes constructed to measure the single dimensions affect economic growth. As the results show, globalization indeed promotes growth. The dimensions most robustly related with growth refer to actual economic flows and restrictions in developed countries. Although less robustly, information flows also promote growth whereas political integration has no effect.     

Do food standards affect the quality of EU imports?

This paper investigates the relationship between the diffusion of EU standards and product quality upgrading using highly disaggregated import data to the EU in the food industry. Results show that, on average, the diffusion of EU voluntary standards boosts the rate of quality upgrading. However, the results are heterogeneous when moving from primary to processed foods, and from ISO to non-ISO standards.     

Do employers avoid hiring workers from poor neighborhoods? Experimental evidence from the real labor market*

We investigate whether employers avoid hiring workers who live in neighborhoods with low socio-economic status and/or with long commuting times. In a large-scale field experiment in the Swedish labor market, we sent more than 4,000 fictitious résumés, with randomly assigned information about the applicants' residential locations, to firms with advertised vacancies. Our findings show that commuting time has a negative effect on the likelihood of being contacted by an employer, while the socio-economic status of a neighborhood does not appear to be important. These results offer guidance for policymakers who are responsible for reversing segregation patterns.     

Are momentum crashes pervasive regardless of strategy? Evidence from the foreign exchange market

This article studies the option-like behaviour of popular momentum strategies implemented in foreign exchange markets. The results confirm recent research findings of strong option-like behaviour for momenutm measures, based on the cumulative return from 12 and 6 months prior to the formation date Surprisingly, there is no such evidence for the popular momentum strategy accounting for a 1-month formation period.     

Immigration and economic freedom of the US states: Does the institutional quality of immigrants' origin countries matter?

When people immigrate to the United States from countries with less economic freedom, they do not dampen economic freedom in their destination states. We use the Economic Freedom of North America report to rate the economic freedom of US states, and we group immigrants by how far below the United States their origin countries score in the Economic Freedom of the World report. Our major findings hold true even when states receive immigrants from countries with far less economic freedom. Most relationships between immigration and the US states' economic freedom scores are neither statistically nor economically significant.     

Do microfinance institutions benefit from integrating financial and nonfinancial services?

This article examines the impact of microfinance ‘plus’ (i.e. coordinated combination of financial and nonfinancial services) on the performance of microfinance institutions (MFIs). Using a global data set of MFIs in 77 countries, we find that the provision of nonfinancial services does not harm nor improve MFIs’ financial sustainability and efficiency. The results however suggest that the provision of social services is associated with improved loan quality and greater depth of outreach.     

Do the skilled and prime-aged unemployed benefit more from training? Effect heterogeneity of public training programmes in Germany

This study analyses the treatment effects of public training programmes for the unemployed in Germany. Based on propensity score matching methods, we extend the picture that has been sketched in previous studies by estimating the treatment effects of medium-term programmes for different skill and age groups. Our results indicate that programme participation has a positive impact on employment probabilities and earnings for almost all sub-groups. We find little evidence for the presence of heterogeneous treatment effects, and the magnitude of the differences is quite small. Our results thus – at least in part – conflict with the strategy to provide training increasingly to individuals with better employment prospects.     

Do liberalization and globalization increase income inequality?

Using the Standardized World Income Inequality Database, we examine if the KOF Index of Globalization and the Economic Freedom Index of the Fraser institute are related to within-country income inequality using panel data covering around 80 countries 1970–2005. Freedom to trade internationally is robustly related to inequality, also when adding several control variables and controlling for potential endogeneity using GMM. Social globalization and deregulation is also linked to inequality. Reforms towards economic freedom seem to increase inequality mainly in rich countries, and social globalization is more important in less developed countries. Monetary reforms, legal reforms and political globalization do not increase inequality.     

Do elites benefit from democracy and foreign aid in developing countries?

A popular argument for the absence of any beneficial effects of foreign aid is that it is skimmed by political elites in recipient countries. However, studies also suggest that aid may be more effective in relatively democratic developing countries. By exploring data on income quintiles derived from the World Income Inequality Database for 88 developing countries, a set of results indicate that foreign aid and democracy in conjunction are associated with a higher share of income held by the upper quintile. It thus appears that foreign aid, contrary to popular beliefs, leads to a more skewed income distribution in democratic developing countries while the effects are negligible in autocratic countries. The paper closes with a discussion of potential mechanisms generating this perverse effect.     

Can social spending cushion the inequality effect of globalization?

This paper examines whether social spending cushions the effect of globalization on within‐country inequality. Using information on disposable and market income inequality and data on overall social spending, and health and education spending from the ILO and the World Bank/WHO, we analyze whether social spending moderates the association between economic globalization and inequality. The results confirm that economic globalization—especially economic flows—associates with higher income inequality, an effect driven by non‐OECD countries. Health spending is strongly associated with lower inequality, but we find no robust evidence that any kind of social spending negatively moderates the association between economic globalization and inequality.     

God save the queen,god save us all? Monarchies and institutional quality

Until the beginning of the 20th century, monarchy was the predominant constitutional form and is still in place today in many countries. However, although a voluminous body of research is concerned with the consequences of constitutions for human development and institutional quality, research on the consequences of monarchy is almost non‐existent. This paper explores the effects of monarchy on economic institutional quality and provides evidence that monarchies are associated with significantly better institutions. Robustness checks indicate that this result cannot be explained through alternative channels such as monarchies being on average richer or smaller.     

Do the Rich Save More? Evidence from Canada

This paper provides new evidence on the long‐standing question of whether more affluent households save a larger fraction of their income. The major difficulty in empirically assessing the relationship between incomes and saving rates is to construct a credible proxy for long‐run income—purged of transitory fluctuations and measurement error. The Canadian Family Expenditure Survey provides us with both unusually good data on savings rates and potential predictors with which we can construct reliable long‐run income proxies. Our empirical analysis suggests that the estimated relationship between saving rates and long‐run incomes is sensitive to the predictor used to proxy long‐run income. Nevertheless, our preferred estimates indicate that, except for poorest households (who simply do not save), saving rates do not differ substantially across predicted long‐run income groups.     

Can everyone benefit from economic integration?

There is no Pareto efficient allocation rule which always encourages economic integration. Further, for any efficient rule treating indistinguishable agents identically in welfare terms, there is an economy in which a third of the agents are hurt upon integration.     

Do central banks act asymmetrically? Empirical evidence from the ECB and the Bank of England

The paper attempts to exploit whether monetary authorities have a different behaviour during recession and expansion. To this end, a multivariate extension of Hamilton Markov-switching model is adopted. First, regime dependent Taylor-type rules are estimated for the Euro Area and the United Kingdom in order to capture the systematic behaviour of central banks. Then, impulse response functions that account for the different phases of the business cycle are analysed. In addition, a comparative analysis concerning the estimated rules as well as the different reaction of real economy to monetary shocks is implemented. The study strongly suggests that central banks cannot neglect the regime where the monetary action takes place. It follows that the phase of business cycle is an important matter in monetary policy decision process.     

Does the minimum wage help the poor?

Conventional economics frequently employs abstract analysis, including questionable assumptions regarding human behavior, together with highly quantitative methodology. While these techniques do not provide a full picture of economic life, conventional economic analysis has provided important insights and predictive power, at least during certain historical periods. The effects of minimum wage laws have been analyzed extensively by conventional economists over the past quarter century. That analysis, much of it empirical, has produced important insights into the effects of the minimum wage on the poor. In this article, I survey that vast body of research and address whether the poor are better off due to the minimum wage. I conclude the minimum wage does not unambiguously help the poor, and may do more harm than good to this segment of the nation's population.
