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...

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...

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...

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?

This paper examines under which conditions religious denomination affects public spending on schooling and educational performance. We employ a unique data
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),...

Untangling trade and technology: Evidence from local labor markets

We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among non-college workers. Labor markets susceptible to computerization due to specialization...

Interhemispheric functional connectivity following prenatal or perinatal brain injury predicts receptive language outcome

Early brain injury alters both structural and functional connectivity between the cerebral hemispheres. Despite increasing knowledge on the individual hemispheric contributions to recovery from such injury, we know very little about how their interactions affect this process. In the present study, we related interhemispheric structural and functional connectivity to receptive...

Can passenger railways curb road traffic externalities? – Empirical evidence

Against a backdrop of road accidents, pollution and congestion, many governments subsidise railways with the aim of reducing such externalities. But do improvements in public transport work? This column argues that recent empirical evidence confirms our expectations and, moreover, that public-transport improvements offer good value for money.

Bank loan announcements and borrower stock returns: Does bank origin matter?

Banks play a special role as providers of informative signals about the quality and value of their borrowers. Such signals, however, may have a quality of their own as the banks’ selection and monitoring abilities may differ. Using an event study methodology, we study the importance of the geographical origin and organization of the banks for the investors’ assessments of firms’...

Applying Negishi’s method to stochastic models with overlapping generations

In this paper we develop a Negishi approach to characterize recursive equilibria in stochastic models with overlapping generations. When competitive equilibria are Pareto-optimal, using Negishi-weights as a co-state variable has three major computational advantages over the standard approach of using the natural state: First, the endogenous state space is a unit simplex and thus easy...

Rethinking the Concept of performance in strategy research: Towards a performativity perspective

Organizational performance is an important concept in strategy research. In this paper, we interrogate the predominant focus on organizational performance as an aggregate organizational-level dependent variable and review three ways in which its role might be fruitfully reconsidered: (1) broadening consideration of performance to more disaggregated levels of analysis, (2) orienting...

Generalized reduced-form auctions: A network-flow approach

We develop a network-flow approach for characterizing interim-allocation rules that can be implemented by ex post allocations. Our method can be used to characterize feasible interim allocations in general multi-unit auctions where agents face capacity constraints, both ceilings and floors. Applications include a variety of settings of practical interest, ranging from individual and...

Oligarchic land ownership, entrepreneurship, and economic development

This paper develops a theory in which oligarchic ownership of land or other
natural resources may impede entrepreneurship in the manufacturing sector and
may thereby retard structural change and economic development. We show that,
due to oligopsony power of owners in the agricultural labor market, higher ownership
concentration depresses entrepreneurial...

Organizational formation and change: lessons from economic laboratory experiments

This chapter reviews research in which economic laboratory experiments are used to shed light on the processes that influence organizational formation and change. An organization, in these experiments, is represented by an abstract collective production activity that takes place in a controlled laboratory setting with incentivized human subjects. The studies typically attempt to...

Portfolio balance effects of the SNB’s bond purchase program

This paper carries out an empirical investigation of the impact on bond spreads of the announcement, purchases and exit from the SNB’s bond purchase program in 2009-2010. We find evidence in favor of a narrowing yield spread of covered bonds as a result of the program. The effect materialized in the days following the announcement of the SNB’s intention to buy bonds issued by private...

Spatial and temporal aggregation in racial profiling

In the last decade, models of rational choice have chimed into the discussion on racial profiling, the use of race in stop and search decisions of the police. The models describe the behavior of motorists and the police and provide empirical tests to assess the question whether the police exhibit racial animus. However, existing studies have neglected the effect of spatial and...
