In this paper we construct a simple model of platform price competition with two main novel features. First, platforms endogenously decide the quality of their `access service' and second, each group exhibits preferences not only about the number of agents in the opposite group, but also about...

Our companion article developed a clear conceptual framework of profit sharing between two rival firms and studied the effects of this strategy on each firm's profit under the assumption that each firm decides unilaterally to give away voluntarily a part of its profit to its rival. This article...

This paper advocates that although an absolute notion of poverty should remain an essential ingredient in the evaluation of the standard of living in developing and transition economies, it is time that relative poverty begins to be systematically estimated for those same economies. This...

Our companion article developed a clear conceptual framework of profit sharing between two rival firms and studied the positive effects of this strategy on each firm's profit under the assumption that each firm decides unilaterally to give away voluntarily a part of its profit to its rival. This...

In contrast to the standard literature, we show that the presence of spillovers may justify temporarily restricting the inflow of foreign direct investment. Our argument is based on two stylized features of spillovers: first, technology transfers --- and subsequent spillovers --- are limited by...

This paper proposes a new empirical approach to assess the impact of knowledge spillovers on firms' productivity and demand. I consider a model where process innovations spillovers to other firms raise firms relative efficiency and technological diffusion of product innovations enhances firms'...

In a vertically differentiated duopoly the use of import tariffs by an importing country decreases domestic welfare if import tariffs are chosen once the firms have made their quality decisions. In this paper we propose import tariffs that are contingent on some minimum quality level (MQL) being...

In this paper, we analyse the recent patterns of occupational segregation by gender in the EU countries vis-á-vis the US. Given the lack of long time-series data on homogeneous LFS data about occupations and educational attainments for male and female workers in EU countries, we use a single...

The reallocation of output across plants and the productivity growth at individual plants are both important sources of productivity growth at the industry level. Recent evidence has shown that trade liberalization is related to both effects. While a trade model with firm heterogeneity can...
