In many service industries the speed of service and support by experienced employees are two major drivers of service quality. When demand for a service is variable and the staffing requirements cannot be adjusted quickly, choosing capacity levels requires making a trade-off between service...

I develop an algorithm to estimate a flexible binary regression model with endogeneity by repeatedly solving a two-stage least squares problem; the algorithm is numerically stable and guaranteed to converge regardless of starting value. The method is numerically stable even when a successful...

The World Trade Organization (WTO) and preferential trade agreements (PTA) are key factors in international trade liberalization. However, their relative effects on trade flows are controversial (ranging from 16 percent to 277 percent), depending on whether the endogeneity of these two variables...

We consider a standard result of customer market theory: if firms have stable customer relations and face financial frictions, they may keep prices relatively high on their locked-in shoppers to maintain short-term profits at the expense of future market shares in times of low demand and vice...

In this article, I develop a novel identification result for estimating the effect of an endogenous treatment using a proxy of an unobserved imperfect instrument. I show that the potential outcomes distributions are partially identified for the compliers. Therefore, I derive sharp bounds on the...

Abstract Staffing decisions typically account for a large portion of a retailer's operational costs. The effectiveness of these decisions has often been analyzed by relating staffing levels to revenues. However, such approach does not explicitly consider the mechanisms by which the staff can...

This paper studies the use of a discrete instrumental variable to identify the causal effect of a endogenous, mis-measured, binary treatment. We begin by showing that the only existing identification result for this case, which appears in Mahajan (2006), is incorrect. As such, identification in...

We consider a standard result of customer market theory: if firms have stable customer relations and face financial frictions, they may keep prices relatively high in times of low demand and vice versa. Indeed, during recessions, when firms have low cash flow and greater difficulty in raising...

The preferences expressed in voting on nuclear reactor licenses and the risk perceptions of citizens provide insights into social costs of nuclear power and decision making in energy policy. We show analytically that these costs consist of disutility caused by unnecessary anxiety - due to...

This paper aims to survey the theoretical and empirical literature on cross-country differences in overeducation. While technological change and globalization have entailed a skill-bias in the evolution of labour demand in the Anglo-Saxon countries, instead, in other advanced economies in...
