On the efficiency of school tracking: a perspective from outcomes in dual VET in Switzerland
In this paper, we examine the efficiency of the sort done by the Swiss lower secondary school tracking system, looking at students’ outcomes in dual vocational education and training (VET)—the most common education type at the upper secondary level in the country. We discuss a simple Ricardian model about the process of school tracking based on the absolute advantage (i.e., the...

Indebtedness for young companies: effects on survival
Based on data from 7 , 350 Cameroonian companies created between 19 90 and 2008, we study the link between the characteristics of indebtedness for young companies during their creation and survival period of up to three years, from three to five years , and beyond five years. We complement our quantitative analysis with semi - dire ctive interviews of Cameroonian entrepreneurs to...

Governance and performance of MFIs: the Cameroon governance case
The main challenge of microfinance institutions and social economy firms remains their survival, and to meet this challenge, MFIs need to be compet-itive. The poor performance of MFIs is usually attributed to their decision-making and operational processes. The governance of MFIs is therefore identified as one of their main risks. Despite this, governance is still little explored in...

Business model innovation: a theoretical perspective and its implications for entrepreneurship research
The business model innovation construct is gaining substantive attention in management literature, emphasizing its role for creating and sustaining a firm’s competitive advantage in rapidly changing business environments. However, little advancement has been made toward a holistic, theory-based understanding of the nature of business model innovation, along with its context-specific...

Contests with small noise and the robustness of the all-pay auction
This paper considers all-pay contests in which the relationship between bids and allocations reflects a small amount of noise. Prior work had focused on one particular equilibrium. However, there may be other equilibria. To address this issue, we introduce a new and intuitive measure for the proximity to the all-pay auction. This allows, in particular, to provide simple conditions...

The limits to moral erosion in markets: social norms and the replacement excuse
This paper studies the impact of a key feature of competitive markets on moral behavior: the possibility that a competitor will step in and conclude the deal if a conscientious market actor forgoes a profitable business opportunity for ethical reasons. We study experimentally whether people employ the argument "if I don’t do it, someone else will" to justify taking a...

Direct Nonlinear Shrinkage Estimation of Large-Dimensional Covariance Matrices
This paper introduces a nonlinear shrinkage estimator of the covariance matrix that does not require recovering the population eigenvalues first. We estimate the sample spectral density and its Hilbert transform directly by smoothing the sample eigenvalues with a variable-bandwidth kernel. Relative to numerically inverting the so-called QuEST function, the main advantages of direct...

Signaling to experts
We study competitive equilibrium in a signaling economy with heterogeneously informed buyers. In terms of the classic Spence (1973) model of job market signaling, firms have access to direct but imperfect information about worker types, in addition to observing their education. Firms can be ranked according to the quality of their information, i.e. their expertise. In equilibrium,...

Gender bias in teaching evaluations
This paper provides new evidence on gender bias in teaching evaluations. We exploit a quasi-experimental dataset of 19,952 student evaluations of university faculty in a context where students are randomly allocated to female or male instructors. Despite the fact that neither students' grades nor self-study hours are affected by the instructor's gender, we find that women...

Does expanding regional train service reduce air pollution?
We assess how regional rail service affects air pollution in Germany, where rail service is procured in auctions or negotiations. We argue that the procurement mode is plausibly exogenous, and show that auctions deliver stronger rail service growth than negotiations. Instrumenting rail service growth with procurement mode, we find that increasing rail service by 10% reduces carbon...

Students are almost as effective as professors in university teaching
Many universities around the world rely on student instructors—current bachelor’s and master’s degree students—for tutorial teaching, yet we know nothing about their effectiveness. In a setting with random assignment of instructors to students, we show that student instructors are almost as effective as senior instructors at improving their students’ short- and longer-run academic...

The determinants of food choice
Health nudge interventions to steer people into healthier lifestyles are increasingly applied by governments worldwide, and it is natural to look to such approaches to improve health by altering what people choose to eat. However, to produce policy recommendations that are likely to be effective, we need to be able to make valid predictions about the consequences of proposed...

Corruption and cooperation
Corruption is a widespread phenomenon. Nevertheless, causal evidence on the effects of corruption is still lacking. In this paper, we assess whether and how corruption affects cooperation using a public good game experiment. Overall, contributions to the public good are reduced by 30% when participants have the possibility to bribe the punishment authority. Two concurrent channels...
