This paper studies the interaction of a minimum quality standard and exports in a vertical product differentiation model when firms sell global products. If exante quality of foreign firms is lower (higher) than the quality of exporting firms, a mild minimum quality standard in the home market...

This paper extends the firm heterogeneity model of Melitz (2003) by introducing a new concept of endegenous investments in process R&D. The novelty is that if a firm invests more R&D its expected innovation return hazard rate stochastically dominates the return of less R&D investments. Due to...

We develop an asymmetric general oligopolistic equilibrium (AGOLE) model, which extends the range of possible applications in general oligopolistic equilibrium modelling. The AGOLE allows to incorporate endogenous and asymmetric marginal utilities of income across countries.As a first exemplary...

In this paper, we analyse the effects of a unilateral change in an emissions tax in a model of international trade with heterogeneous firms. We find a positive effect of tighter environmental policy on average productivity in the reforming country through reallocation of labour towards exporting...

In this paper, we develop a multi-country open economy extension of the famous Big Push model for a closed economy by Murphy et al. (1989). We show under which conditions the global economy in our model is caught in a poverty trap, characterised by a low-income equilibrium from which an escape...

Applied general and partial equilibrium models are widely used tools for ex ante analysis of trade policy changes. However, simulation results seem to exhibit significant variation across publications, and the often criticised 'black box' character of applied trade models makes meaningful...

The nature of international trade has changed significantly. For centuries, trade concentrated on the exchange of finished goods. It now increasingly involves bits of value that are added at different locations to combine into one final product. Therefore, trade in functions or tasks are of...

This paper investigates the effects of trade liberalisation induced labour demand shocks on informal employment in China. We employ a local labour market approach to construct a regional measure of exposure to import tariffs by exploiting initial differences in industrial composition across...

We estimate the effect of the introduction of robots on the intensive and extensive margins of exports using a sample of Spanish manufacturing firms over the period 1994-2014. The empirical strategy used to identify the causal impact of robot adoption on the firm level export performance...

This paper investigates the impact of import liberalization induced labor demand shocks on male and female employment in China. Combining data from population and firm census waves over the period of 1990 to 2005, we relate prefecture-level employment by gender to the exposure to tariff...
