Firm Heterogeneity, Credit Constraints, and Endogenous Growth

This paper is concerned with the role of firm heterogeneity under credit constraints for economic growth. We focus on firm size, innovativeness and credit constraints in a semi-endogenous growth model reflecting recent empirical findings on firm heterogeneity. It allows for an explicit solution for transitional growth and balanced growth path productivity as well as the growth maximizing firm heterogeneity. This enables us to draw inference about the impact of key policy parameters of the model on these quantities and to draw conclusions about firm and capital market related policies.firm heterogeneity, credit constraints, firm size, SME, economic growth

Decomposing Firm-level Sales Variation

We measure the contribution of firm-specific effects to overall sales variation within a destination and find it remarkably low. Our empirical decomposition is structurally motivated by a heterogeneity model of exporting involving destination-specific, firm-specific, and firm-destination-specific latent effects with incidental truncation. We use a highly detailed dataset with exports by products and destinations for all Danish manufacturing firms. We find the contribution of firm-specific heterogeneity to within-destination sales variation varies greatly across HS6 products, and that for the median product it drives 31% of the sales variation. When we remove first-time exports from our sample, the median value increases to 40%, implying that firm-destination-specific effects are most important the first year. We conclude that while firm-specific productivity can account for some of the variation, the majority is explained by firm-destination-specific heterogeneity sources such as firm-destination-specific demand.firm heterogeneity; firm-level export data; truncation correction

Trade and mergers in the presence of firm heterogeneity

We investigate the role of firm heterogeneity in considering profitability and desirability of mergers in the international economy. Analysis shows that higher trade costs make only crossborder mergers profitable whereas larger firm heterogeneity is likely to increase both domestic and cross-border mergers. Furthermore, it is shown that whether or not a merger leads to merger waves depends on the types of firms involved in it. It is also demonstrated that larger firm heterogeneity can reduce the discrepancy between profitability and desirability of mergers when the trade cost is sufficiently low.M&As, trade, firm heterogeneity, Cournot competition

Home market effect, regulation costs and heterogeneous firms

This paper studies how market-specific entry sunk costs (regulation costs) affect the Home Market Effect (HME) with firm heterogeneity in marginal costs. our model is based on the Dixit-Stiglitz monopolistic competition model with firm heterogeneity plus regulation costs difference. We find that a regulation costs gap works as dispersion force by inducing a market potential gap, which reduces the HME and could cause the reverse HME or the anti-HME. The HME first rises and then fall in terms of trade openness, whereas the HME rises in terms of regulation costs gap coordination by technical barriers to trade (TBT) agreements. Firm heterogeneity dampens the dispersion force by the regulation costs difference and thus works as an agglomeration force. Firm heterogeneity causes a perfect spatial sorting, in which a large country attracts only high productivity firms, and vice versa.Home market effect, firm heterogeneity, regulation costs, technical barriers to trade.

Agglomeration, Trade and Selection

This paper studies how firm heterogeneity in terms of productivity affects the balance between agglomeration and dispersion forces in the presence of pecuniary externalities through a selection model of monopolistic competition with variable mark-ups. It shows that firm heterogeneity matters. However, whether it shifts the balance from agglomeration to dispersion or the other way round depends on its specific features along the two defining dimensions of diversity: 'richness' and 'evenness'. Accordingly, the role of firm heterogeneity in selection models of agglomeration cannot be fully understood without paying due attention to various moments of the underlying firm productivity distribution.agglomeration, trade, heterogeneity, selection, economic geography

Firm Heterogeneity and Firm Behavior with Conditional Policies

This paper shows that the result of Ju and Krishna (2002, 2005), i.e., the non-monotonicity in the comparative statics across regimes, disappears, if exporters differ in their productivities, which provides very different predictions about the results of policy changes.

Home Market Effect and Regulation Costs - Homogeneous Firm and Heterogeneous Firm Trade Models

This paper studies how market-specific entry sunk costs (regulation costs) affect the Home Market Effect (HME) with firm marginal costs heterogeneity. Our model is based on the Dixit-Stiglitz monopolistic competition model with firm heterogeneity plus regulation costs difference. We find that a regulation costs gap works as dispersion force by inducing a market potential gap, which reduces the HME and could cause the reverse HME or the anti-HME. The Home Market Magnification Effect (HMME) in terms of trade openness is hump-shaped, whereas the pro-HMME in terms of regulation costs coordination by technical barriers to trade (TBT) agreements can be found. Firm heterogeneity dampens the dispersion force by the regulation costs difference and thus works as an agglomeration force. Firm heterogeneity causes a perfect spatial sorting, in which a large country attracts only high productivity firms and vice versa.regulation costs, market potential, perfect spatial sorting, home market effect, home market magnification effect, firm heterogeneity, technical barriers to trade

Firm Heterogeneity: do destinations of exports and origins of imports matter?

How do importing activities matter in explaining firm heterogeneity? How firm performances are related to foreign markets heterogeneity? Using a rich database on Italian manufacturing firms, this essay adds new evidence on the relationship between trade status and firm characteristics. We uncover evidence supporting recent theories on firm heterogeneity and international trade, together with some new facts. First, the availability of information on import and export enables us to differentiate firms involved in both trading activities - namely two-way traders - from firms that only export, and from those that only import. We show that firms engaged in both import and export outperform those involved in either importing or exporting only. Second, exploiting firm-level information on the destination of export and the origin of imports, we observe the heterogeneity among firms trading with different type of markets. We show that different destinations of exports and different origins of imports map into distinctive firm characteristics.heterogeneous firms; exports; imports; productivity, performances, destinations

Cultural Links, Firm Heterogeneity and the Intensive and Extensive Margins of International Trade

It is well known that cultural links between countries increase bilateral trade. In this paper we exploit Portuguese firm-level data on exports to 199 destinations to investigate the questions: How? Do cultural links increase the number of exporters, or the shipments per exporter? What is the role of firm heterogeneity? The results reveal that cultural links, measured by common language/colonial ties and emigrant communities, are significantly associated with a lower incidence of within-firm export zeros and with larger shipments per exporter. Furthermore, they show that the former of these relationships tends to be magnified by firm size, suggesting that firm heterogeneity is key in shaping the interplay between cultural links and the extensive margin of international trade.Colonial ties, migration, firm heterogeneity, intensive and extensive margins
