How do Multiproduct Exporters React to a Change in Trade Costs?*

We use data on individual French exporters to document how a change in trade costs, following the introduction of the euro, affected the export margins of firms in relation to export decisions, the number of products exported, and the average sales per product. Our results confirm two effects predicted by the theory: firms increase the range of products they export as well as their intensive margin. This effect is most evident in markets with moderate monetary policy coordination before 1999. General equilibrium competition effects reduce the initial positive impact on each of these margins. We find no evidence that firms increase their participation in the export market.     

How Much is Too Much?

In a split sample design, we examine how the number of choice sets, design of the first choice set (context dependence), and the choice of attribute levels in the cost attribute affect the precision in the elicited preferences in otherwise completely identical choice experiment surveys. These issues are investigated for Swedish households’ marginal willingness to pay to reduce power outages. Our results indicate that neither the number of choice sets nor the design of the first choice set has a significant impact on estimated marginal willingness to pay, while the effect was significant for the additive scaling of the cost vector. At the end of the article we discuss the implications of our results on future developments and applications of choice experiments.      

Do Employees’ Sickness Absences React to a Change in Costs for Firms? Evidence from a Natural Experiment*

We analyse the impact of a social security reform that changed the costs incurred by firms due to sickness absences. The reform abolished a compulsory insurance for firms, which insured them against the wages paid to sick blue-collar workers. During the first year after its introduction, we estimate that the reform resulted in about 6.3 percent fewer sickness absences, and in about 8.6 percent fewer absence days. We do not find evidence for changes in hiring or firing, and we find only limited workforce composition changes. We do not find spillover effects on the absences of white-collar workers. Robustness checks confirm these results.     

How Much Did Oil Market Developments Contribute to the 2009 Recession in Germany?

In this paper, we use a structural vector autoregressive model to study the effects of oil market developments on the German economy. We find that higher oil prices are always associated with a decline in private consumption expenditures, but the response of gross domestic product (GDP) crucially depends on the underlying shock. While a disruption in oil supply provokes a recession, positive world demand shocks prompt a temporary increase in exports and investment, which initially outweigh the cutback on consumption. In a counterfactual analysis, we show that the world demand shocks that led to the 2007/2008 oil price rise triggered a delayed 0.8 percent decrease in German GDP in 2009, and therefore notably contributed to the recession of that year.     

Does unemployment lead to a less healthy lifestyle?

In this article, we use 22 years of data from the German Socio-Economic Panel and information on plant closures to investigate the effects of unemployment on four indicators of unhealthy lifestyles: diet, alcohol consumption, smoking and (a lack of) physical activity. In contrast to much of the existing literature, which unlike our analysis is unable to assess causality, our results provide little evidence that unemployment gives rise to unhealthy lifestyles.     

Does labour supply respond to a flat tax?

We exploit the exogenous change in marginal tax rates created by the Russian flat tax reform of 2001 to identify the effect of taxes on the labour supply of men and women. We apply a weighted difference‐in‐difference regression approach and instrumental variables to estimate labour supply functions using a panel dataset. The mean regression results indicate that the tax reform led to a statistically significant increase in hours of work for men but had no effect on work hours for women. However, we find a positive response to tax changes in both tails of the female work hour distribution. We also find that the reform increased the probability of finding a job among both men and women. Despite significant variation in individual responses, the aggregate labour supply elasticities are trivial. This suggests that reform‐induced changes in labour supply are an unlikely explanation for the amplified personal income tax revenues that followed the reform.     

Does Inequality Lead to a Financial Crisis? Revisited

Financial crises have been attributed to rising income inequality via its induced high household leverage as observed in the USA and similar economies. Alternatively it has been suggested this is not a general relationship since it was found that inequality had no bearing on crises in 14 advanced countries over 1920–2008; instead, low interest rates and business cycle expansions are found to be the only two robust determinants of credit booms leading to crises. Using a similar dataset, this paper provides no support for the generality of the above findings by embracing country heterogeneity. The paper shows that real evidence still points back to the inequality‐leverage–crisis nexus for financialized economies. The implication is that finance can hardly be sustainable under rising inequality.     

How Much Income Mobility is There in Britain?

Using the first four waves of the British Household Panel Survey (1991–4) and a variety of methods, we show that there is much mobility in household net income from one year to the next in Britain. However most income changes from one year to the next are not very large, and when incomes are longitudinally averaged so that transitory variations are smoothed out, substantial 'permanent' income differences are revealed. There is some evidence of greater mobility for those in the tails of the income distribution relative to the middle, and for elderly persons compared to non-elderly persons     

How Does FDI Affect Health?

This paper investigates the impact of foreign direct investment (FDI) on population health using panel data for up to 179 countries for the period between 1980 and 2011. Our main finding is that the relationship between FDI and health is nonlinear, depending on the level of income: FDI has a positive effect on health at low levels of income, but the effect decreases with increasing income, then changes sign and becomes increasingly negative at higher levels of income.     

How Elastic is East Asian Demand for Consumption Goods?

This paper investigates import demand in East Asia. Estimating exchange rate elasticities for countries in the region is difficult because many imports are used to produce goods for re‐export. An exchange rate appreciation that reduces East Asian exports will also reduce the demand for imported inputs that are used to produce exports. To correct for this bias this paper examines consumption imports, since these goods are intended primarily for the domestic market. Results from several specifications indicate that currency appreciations and increases in income in East Asian countries would significantly increase imports into the region.     

How to hire helpers? Evidence from a field experiment

How to hire voluntary helpers? We shed new light on this question by reporting a field experiment in which we invited 2859 students to help at the ‘ESA Europe 2012’ conference. Invitation emails varied non-monetary and monetary incentives to convince subjects to offer help. Students could apply to help at the conference and, if so, also specify the working time they wanted to provide. Just asking subjects to volunteer or offering them a certificate turned out to be significantly more motivating than mentioning that the regular conference fee would be waived for helpers. By means of an online-survey experiment, we find that intrinsic motivation to help is likely to have been crowded out by mentioning the waived fee. Increasing monetary incentives by varying hourly wages of 1, 5, and 10 Euros shows positive effects on the number of applications and on the working time offered. However, when comparing these results with treatments without any monetary compensation, the number of applications could not be increased by offering money and may even be reduced.

Who Pays a Price on Carbon?

We use the 2003 Consumer Expenditure Survey and emissions estimates from an input-output model based on the 1997 US economy to estimate the incidence of a price on carbon induced by a cap-and-trade program or carbon tax in the context of the US. We present results on how much different income deciles pay for a carbon tax as well as which industries see the largest increase in costs due to a carbon tax. We illustrate the main determinant of the regressivity: consumption patterns for energy-intensive goods. Furthermore, on a per-capita basis a carbon price is much more regressive than calculations at the household level. We discuss policy options to offset the adverse distributional effects of a carbon emissions policy.     

How Much Does the State of the Economy Influence the Popularity of Austrian Parties? An Empirical Investigation

We estimate popularity functions for the Austrian parties Austrian People’s Party (ÖVP), Social Democrats (SPÖ) and Austrian Freedom party (FPÖ) between 1987 and 2010 (using annual data) as well as vote functions for the same Austrian parties in the 86 election districts in the national elections in 1999, 2002, 2006 and 2008. In most cases we find a statistically significant and theoretically predicted influence of three economic variables, namely the unemployment rate, inflation rate and growth rate of income, on both popularity and voting behavior. However, this influence is not robust and shows a tendency to decline over time.     

How close is Asia already to being a trade bloc?

FTA bilateral and regional negotiations in Asia have developed quickly in the past decade moving Asia ever closer to an economic union. This paper uses a fifteen-country global general equilibrium model with trade costs to numerically calculate Debreu distance measures between the present situation and potential full Asia integration in the form of a trade bloc. Our results reveal that these large Asia economies can be close to full integration if they act timely in agreements through negotiation. All Asia countries will gain from Asia trade bloc arrangements except when the Asia FTA can only eliminate tariffs. These countries’ gain will increase as bilateral non-tariff elimination deepens. Larger countries will gain more than small countries. Asia FTA, Asia Union and RCEP will benefit member countries more than ASEAN+3. Global free trade will benefit all countries the most.     

How much of a threat to economic growth is a mature AIDS epidemic?

The article models the impact on economic growth of HIV/AIDS when the epidemic is in a mature phase, in contrast with previous studies focused on periods of expansion as it is typically the case in African countries. Simulations for Honduras, the epicentre of the epidemic in Central America, show that AIDS is not likely to threaten economic growth neither through labour nor capital accumulation channels. Impacts are estimated between 0.007 and 0.27% points of Gross Domestic Product (GDP) growth annually for the period 2001 to 2010. Increasing spending on prevention, higher public treatment subsidies and increasing treatment access will not jeopardize economic growth prospects. Critical factors that slash economic growth in Africa (such as human capital reductions and shifts in relative skills) are not strong in Honduras.
