Intermediaries and wholesalers play an important role in international trade. This paper develops a model of international trade with heterogeneous firms that offers an explanation of the existence of wholesalers. All exporting firms have to pay a fixed cost of establishing a distribution...

This paper explores sector differences in how the gender wage gap varies across the wage distribution and the role of occupational segregation in explaining this variation for Sweden. Results indicate that the phenomenon known as the glass ceiling, i.e. larger gender wage differentials at the...

Inflation forecasts made 1999-2005 by Sveriges Riksbank and Konjunkturinstitet of Swedish inflation rates 1999-2007 are tested for unbiasedness; i.e., are the mean forecast errors zero? The bias is in the order of -0.1 percentage units for horizons below one year and in the order of 0.1 and 0.6...

The purpose of this paper is to examine the effectiveness of the policies and procedures towards economic convergence between the countries that participated in the European Exchange Mechanism I and which are now members states of the Eurozone. The question posed is whether the introduction of...

We develop a model of outsourcing and trade in service inputs where the scope of tasks produced by both manufacturing firms and service providers is endogeneous. Manufacturing firms have to perform a fixed set of tasks in order to produce their final good but can decide to outsource some of...

The LASSO is a widely used statistical methodology for simultaneous estimation and variable selection. In the last years, many authors analyzed this technique from a theoretical and applied point of view. We introduce and study the adaptive LASSO problem for discretely observed ergodic diffusion...

Using a probit model we empirically estimated the role of emotional factors in determining household participation in the debt market, after controlling for traditional economic predictors, such as age, level of education, income, wealth, and work status. A sample of 445 Caucasian subjects,...

After many explorations in different directions during the early 1930s, in 1934 Hicks ends up by advocating an interpretation of Walrasian equilibrium and capital theory along stationary lines, but the suggested interpretation is at variance with the view endorsed by the last Walras and by...

This paper studies the impact of endogenous population change on economic growth, analyzing the simplest optimal endogenous growth model, an AK type model, driven by human capital accumulation. We show that in steady state both demographic change and economic growth are constant, but the rate of...

We consider a dynamical system with small noise where the drift is parametrized by a finite dimensional parameter. For this model we consider minimum distance estimation from continuous time observations under some penalty imposed on the parameters in the spirit of the Lasso approach. This...
