We propose a generalization of the linear quantile regression model to accommodate possibilities afforded by panel data. Specifically, we extend the correlated random coefficients representation of linear quantile regression (e.g., Koenker, 2005; Section 2.6). We show that panel data allows the...

This paper investigates empirically whether inward greenfield foreign direct investment (FDI) is related to greater sectorial innovation in the host Italian provinces. We combine several sources of data to estimate panel count models, regressing the annual number of patents in each province and...

The paper adds to the scattered empirical evidence on the role of obstacles to innovation in a three-fold way. First, we correct for the usual sample selection bias by filtering out firms not interested in innovation from ‘potential innovators’. Second, we assess what mostly affects firms’...

This paper examines how firm age can affect a firm’s perception of the obstacles (deterring vs. revealed) that hamper and delay innovation. Using a comprehensive panel of Spanish firms for the period 2004-2011, the empirical analysis conducted shows that distinct types of obstacle are...

This empirical paper tests for trade-facilitated spillovers in the convergence of energy productivity across 16 European Union (EU) countries from 1995 to 2005. One might anticipate that by inducing specialization, trade limits the potential for convergence in energy productivity. Conversely, by...

This paper investigates the quasi-maximum likelihood (QML) estimation of spatial panel data models where spatial weights matrices can be time varying. We show that QML estimate is consistent and asymptotically normal. We also derive the asymptotic distribution of average impact coefficients...

Even before the events of the past few years, economists and policy makers were musing about the apparent contradiction between globalization, as it is generally understood, and the seemingly different paths in overall economic activity taken by the emerging and more mature economies of the...

We estimate Okun coefficients for five different age cohorts for several Eurozone countries. We find a stable pattern for all countries: The relationship between business-cycle fluctuations and the unemployment rate is the strongest for the youngest cohort and gets smaller for the elderly cohorts.

This paper studies the evolution of life satisfaction over the life course in Germany. It clarifies the causal interpretation of the econometric model by discussing the choice of control variables and the underidentification between age, cohort and time effects. The empirical part analyzes the...

We discuss the difficult question of measuring the effects of asymmetric information problems on resource allocation. Three problems are examined: moral hazard, adverse selection, and asymmetric learning. One theoretical conclusion, drawn by many authors, is that information problems may...
