Despite their importance, the discussion of spillover effects in empirical research often misses the rigor dedicated to endogeneity concerns. We analyze a broad set of workhorse models of firm interactions and show that spillovers naturally arise in many corporate finance settings. This has...

This article performs an analysis of the relationship that exists between economic growth and the environment in the 32 states of the Mexican Republic. The Environmental Kuznets Curve (EKC) suggests that there is indeed a relationship between economic growth and the environment. As economies...

This paper investigates the determinants of Italian regional specialization in the period 1995-2006. In particular, it tests and evaluates the presence of spatial autocorrelation in sectoral specialization patterns by the use of spatial econometrics tools. Results show positive effects of...

This paper assesses whether per-capita income, measured as average wages and salaries per job, in U.S. nonmetropolitan counties is converging to the national or U.S. metropolitan average using data over the 1969 to 2004 period. Additional analysis explores whether per-capita income is converging...

Since Mandelbrot's seminal work (1963), alpha-stable distributions with infinite variance have been regarded as a more realistic distributional assumption than the normal distribution for some economic variables, especially financial data. After providing a brief survey of theoretical results on...

Likelihood functions of spatial autoregressive models with normal but heteroskedastic disturbances have been already derived [Anselin (1988, ch.6)]. But there is no implementation for maximum likelihood estimation of these likelihood functions in general (heteroskedastic disturbances) cases....

In a Regression Kink (RK) design with a finite sample, a confounding smooth nonlinear relationship between an assignment variable and an outcome variable around a threshold can be spuriously picked up as a kink and result in a biased estimate. In order to investigate how well RK designs handle...

We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to evaluate the effectiveness of the Job Corps (JC) training program for disadvantaged youth. We concentrate on the population average treatment effect (ATE) and the average...

A growing literature on inference in difference-in-differences (DiD) designs with grouped errors has been pessimistic about obtaining hypothesis tests of the correct size, particularly with few groups. We provide Monte Carlo evidence for three points: (i) it is possible to obtain tests of the...

In this paper we explore the application of Generalised Additive Models of Location, Scale and Shape for the analysis of conditional income distributions in Germany following the reunification. We find that conditional income distributions can generally be modelled using the three parameter...
