In this paper, we build a dynamic model with endogenous firm-level productivity that generates firm heterogeneity as an equilibrium outcome. Firm heterogeneity arises in equilibrium from the gradual diffusion of a technological innovation through the industry. We investigate the effects of...

This paper presents theory and evidence from Chinese firm-product data that, given firm productivity, trade liberalization increases product markups. This finding calls for a reconsideration of the well-established imports-as-market-discipline hypothesis. This paper further verifies underlying...

In practice, we often observe that as part of their dual-channel distribution structure, foreign manufacturers carry out foreign direct investment and sell products through domestic retailers, and export products directly through their own EC sites, thereby incurring an export tariff. We revisit...

This paper presents theory and evidence from Chinese firm-product data that, given productivity, trade liberalization via input tariff reductions induces an incumbent importer/exporter to increase product markups. This finding calls for a reconsideration of the well-established...

This paper develops a general equilibrium model of multi-product firms and analyzes their behavior during trade liberalization. Firm productivity in a given product is modeled as a combination of firm-level "ability" and firm-product-level "expertise", both of which are stochastic and unknown...

Despite the importance of international trade on intermediate goods, the literature did not pay much attention to this aspect in determining the effects of trade liberalisation in the presence of labour unions. We take up this issue here and show the effects of trade liberalisation on the final...

We offer a new perspective to the unionised wage effects of unilateral trade liberalisation by considering endogenous domestic market structure. Hence, in contrast to the existing works, which focus on the short-run effects of trade liberalisation on unionised wage, we focus on more long-run...

This paper suggests a quantifiable multi-sector-multi-country economic model of goods and services production and consumption. It calibrates overall (variable and fixed) costs to market-specific sales by sector and decomposes these costs into observable and unobservable components. In an...

We construct a model of trade with heterogeneous retailers to examine the effects of trade liberalization on retail market structure, imports and social welfare. We are especially interested in studying the degree of pass-through of import into retail prices and the effects of retail market...
