Market size, division of labor, and firm productivity

We generalize Krugman's (1979) ‘new trade’ model by allowing for an explicit production chain in which a range of tasks is performed sequentially by a number of specialized teams. We demonstrate that an increase in market size induces a deeper division of labor among these teams which leads to an increase in firm productivity. The paper can be thought of as a formalization of...

A bargaining theory of trade invoicing and pricing

We develop a theoretical model of international trade pricing in which individual exporters and importers bargain over the transaction price and exposure to exchange rate fluctuations. We find that the choice of price and invoicing currency respects the full market structure, including the extent of fragmentation and the degree of heterogeneity across importers and across exporters...

Trade effects of export taxes

Export taxes usage has recently risen. They are widely presumed to affect trade, but the lack of data has prevented a systematic evaluation of their trade effects. Based on a new dataset of tax rates at the product level, this paper estimates the distortionary trade effects of export taxes. The results, which are based on theory-consistent estimation of a structural gravity model,...

Women's emancipation through education: a macroeconomic analysis

In this paper, we study the role of education as insurance against a bad marriage. Historically, due to disparities in earning power and education across genders, married women often found themselves in an economically vulnerable position, and had to suffer one of two fates in a bad marriage: either they get divorced (assuming it is available) and struggle as low-income single...

HR-Committees: Bedeutung von Nominierungs- und Entschädigungsausschüssen auf Stufe Verwaltungsrat

Der VR einer AG muss als strategisches Führungsorgan zahlreiche personalpolitische Aufgaben erledigen, von denen nur ein Teil an die GL delegiert werden kann. Ein kombinierter Nominierungs- und Entschädigungsausschuss mit zusätzlichen HRM-Aufgaben ist dabei eine echte Hilfe. Ein solches HR-Committee kann zudem die Gefahr einer Machtkonzentration beim VR-Präsidenten oder beim VR-...

License to cheat: Voluntary regulation and ethical behavior

Although monitoring and regulation can be used to combat socially costly unethical conduct, their intended targets can often avoid regulation or hide their behavior. This surrenders at least part of the effectiveness of regulatory policies to firms’ and individuals’ decisions to voluntarily submit to regulation. We study individuals’ decisions to avoid monitoring or regulation and...

Does community driven development work? : evidence from Senegal

Community Driven Development (CDD) programs are an extremely important component of the World Bank’s portfolio in the developing world, representing close to $7 billion in 2003, yet solid empirical evidence on their impact is relatively scarce, especially for Subsaharan Africa. In this paper, we consider the impact on access to basic services, household expenditures and child...

Essential heterogeneity in the impact of community driven development

We consider essential heterogeneity in the impact of a large-scale Community-Driven Development (CDD) program in Senegal. Essential heterogeneity arises when unobservables determine the idiosyncratic gains from participation in a program, thereby generating correlation between treatment effects and selection. Standard instrumental variables estimates are shown to provide an extremely...

Adjustment Policy of Deposit Rates in the Case of Swiss Non-maturing Savings Accounts

Retail banks usually apply simple linear regression models for describing the dynamics of the deposit rates of non-maturing accounts (NMA) like savings deposits. Thus, typical patterns like asymmetry or rigidity that banks follow when adjusting their deposit rates are ignored. This is insofar surprising, as the asymmetric deposit rate adjustment affects the pricing of embedded...

European capitals of culture and life satisfaction

This paper analyzes whether hosting the most prestigious European cultural event, the European Capital of Culture, has an impact on regional economic development or the life satisfaction of the local population. Concerning the economic impact, we show that European Capitals are hosted in regions with above average GDP per capita, but do not causally affect the economic development in...

The all-pay auction with complete information and identity-dependent externalities

We derive a necessary and sufficient condition for the existence of equilibria with only two active players in the all-pay auction with complete information and identity-dependent externalities. This condition shows that the generic equilibrium of the standard all-pay auction is robust to the introduction of "small" identity-dependent externalities. In general, however, the...

Extended unemployment benefits and early retirement: program complementarity and program substitution

This paper explores how extended unemployment insurance (UI) benefits targeted to older workers affect early retirement and social welfare. The trade-off of optimal UI between consumption smoothing and moral hazard requires accounting for the entire early retirement system, which often includes extended UI and relaxed access to disability insurance (DI). We argue that extended UI...

Under which conditions does religion affect educational outcomes?

set which covers, inter alia, information on numerous measures of public school inputs in 169 Swiss districts for the years 1871/72, 1881/82 and 1894/95, marks from
pedagogical examinations of conscripts (1875-1903),...
