Risk sharing and export performance with firm heterogeneity

We investigate how market uncertainty affects the export performance of a firm through financial frictions. We first extend Melitz's (2003) heterogeneous firm trade model by incorporating demand shocks, linking the demand uncertainties to the financing costs of firms. In this extension, the default probability is endogenously determined by a firm's productivity and demand uncertainty. Hence, firms with higher productivity or lower market uncertainty are offered lower interest rates and thus show better export performance. As an application, we also show that a risk-sharing mechanism, that pools default risk for a certain group of firms, lowers the default risk. This mechanism allows banks to charge lower interest rates to the member firms and therefore ultimately improves their export performance in both extensive and intensive margins. We find a real-world example of such a mechanism from business groups in Korea. Using Korean firm-level data, we show that the more diversified the business group, the greater the likelihood that its member firms export and the bigger their export revenues. We also show that our results are robust to alternative explanations for Korean business groups’ export competitiveness.     

FIRM DYNAMICS IN AN URBAN ECONOMY *

We develop a new dynamic general equilibrium model to explain firm entry, exit, and relocation decisions in an urban economy with multiple locations and agglomeration externalities. We characterize the stationary distribution of firms that arises in equilibrium. We estimate the parameters of the model using a method of moments estimator. Using unique panel data collected by Dun and Bradstreet, we find that agglomeration externalities increase the productivity of firms by up to 8%. Economic policies that subsidize firm relocations to the central business district increase agglomeration externalities in that area. They also increase economic welfare in the economy.     

Ownership structure and diversification in a scenario of weak shareholder protection

This work examines the influences of ownership concentration and insider ownership on corporate strategies for diversification within a scenario characterized by poor protection of shareholder interests. We find evidence of a quadratic relationship between ownership concentration and diversification, and a cubic relationship between diversification and insider ownership. These results point towards the high probability of both expropriation and entrenchment phenomena, respectively, in this kind of scenario. We also find that concentrated ownership requires high levels of insider ownership, in order to prevent negative externalities of diversification. Another result shows that entrenchment externalities affect diversification before they erode firm value, which suggests that for low levels of diversification, firm value is still not negatively affected. Additionally, our results show that control mechanisms, such as debt, director remuneration and compliance with codes of good practice, are negatively related to the level of diversification. Overall, our results confirm the theoretical relevance of agency theory in explaining managerial attitudes towards corporate strategy, i.e. diversification. Furthermore, companies characterized by deficiencies in shareholder legal protection, concentrated ownership structures and a higher likelihood of managers being entrenched, should focus on the correct functioning of corporate governance mechanisms.     

To Ban or Not to Ban: Foreign Lobbying and Cross‐National Externalities

This paper studies the costs and benefits of foreign lobbying. We show how and when foreign lobbying can help internalize cross‐national externalities. We argue that this is an often overlooked benefit of foreign lobbying. We also study under what conditions a constitutional rule banning foreign lobbying is in the national interest of a country. A key factor in this calculus is whether the interests of foreign lobby groups and domestic unorganized groups coincide or not. We illustrate the logic with examples from trade policy and environmental regulation.     

Commercial Policy and Foreign Ownership

Foreign multinationals often not only export but also control local firms through FDI. This paper examines the various effects of trade and industrial policies when exports and FDI coexist. We focus on the case in which a foreign firm has full control of a local firm through partial ownership. Cross‐border ownership on the basis of both financial interests and corporate control leads to horizontal market linkages through which tariffs and production subsidies may harm locally owned firms but benefit the foreign firm. Foreign ownership regulation benefits locally owned firms. These results could have strong policy implications for developing countries that attract an increasing share of world FDI.     

Firms,kinship networks,and economic growth in the Kyrgyz Republic

While kinship ties support private sector development, they can also lead to economic inefficiencies. The paper examines the impact of kinship networks on firm performance and growth based on our original survey of 1000 firm owners in the Central Asian Republic of Kyrgyzstan. We obtained detailed information on respondents’ business networks, resources they both receive from (in-networks) and provide to their kin and other contacts (out-networks) and their firm's performance. Our results indicate that in-networks raise profitability, out-networks reduce it, and these two forms of network usage are positively, but far from perfectly, correlated. We also show that kin-reliant firms grow slower than firms with access to non-kin assistance but faster than firms that do not have access to any business networks at all. We find evidence that one mechanism of slower growth is lower levels of reinvestment. We conclude that accounting for in- and out-networks helps to resolve the ambiguous message from the broader empirical literature regarding the effect of kin networks on firm performance: the two forms of network use are positively correlated, most likely due to generalized reciprocity within kin networks, yet have opposite effects.     

The relationship among enterprise clustering,prices, and productivity in Ethiopia’s manufacturing sector

We use census panel data on Ethiopian manufacturing firms to analyze how enterprise clustering in local markets covaries with firm‐level output prices and physical productivity. We find a negative and statistically significant relationship between the density of firms that produce a given product in a given location and the local price of that product. We also find a positive and statistically significant relationship between the density of firms that produce a given product in a location and the physical productivity of same‐product firms in the location. These results are consistent with the notion that increased clustering of firms generates higher competitive pressure and positive externalities. Across firms that produce different products, we find no statistically significant relationship between enterprise clustering and firm‐level output prices and productivity. We also find no clustering effects across towns. Our results suggest that while clustering can impact firm performance, the advantages are narrow in scope.     

The impact of trade on employment,welfare, and income distribution in unionized general oligopolistic equilibrium

This paper sets up a multi-sector general oligopolistic equilibrium trade model in which all firms face wage claims of firm-level unions. By accounting for productivity differences across industries, the model features income inequality along multiple lines, including inequality between firm owners and workers as well as within these two groups of agents, and involuntary unemployment. We use this setting to study the impact of trade liberalization on key macroeconomic performance measures. In particular, we show that a movement from autarky to free trade with a fully symmetric partner country lowers union wage claims and therefore stimulates employment and raises welfare. Whether firms can extract a larger share of rents in the open economy depends on the competitive environment in the product market. Furthermore, the distribution of profit income across firm owners remains unaffected, while the distribution of wage income becomes more equal when a country opens up to trade with a fully symmetric trading partner. We also analyze how country size differences and technological dissimilarity of trading partners affect the results from our analysis.     

Indeterminacy in dynamic models: When Diamond meets Ramsey

We consider an aggregate two-periods overlapping generations model with endogenous labor, consumption in both periods of life, homothetic preferences and productive external effects coming from the average capital and labor. We show that under realistic calibrations of the parameters, in particular a large enough share of first period consumption over the wage income, local indeterminacy of equilibria cannot occur with capital externalities alone. It can nevertheless occur when there are only, even very small, vanishing labor externalities provided that the elasticity of capital-labor substitution and the wage elasticity of the labor supply are large enough. We also show that if labor externalities are slightly stronger, but still small enough to be plausible, and the elasticity of labor supply is larger, local indeterminacy occurs in a Cobb-Douglas economy. Finally, we show that a locally indeterminate steady state is generically characterized by an under-accumulation of capital. It follows therefore that while agents live over a finite number of periods, the conditions for the existence of locally indeterminate equilibria are very similar to those obtained within infinite horizon models and that from this point of view, Diamond meets Ramsey.     

Endogenous City Formation with Production Externalities: Existence of Equilibrium

I show that equilibria exist in closed city‐system models with production externalities if firms' production possibilities vary continuously with the source of the externality, are constant returns to scale in own inputs, include inaction, and satisfy free disposal; if firms have to employ their own inputs to produce output; if there is a finite number of firm types; and if some standard conditions on preferences and endowments are satisfied. This is the first model to include production externalities in the fully general equilibrium framework required for endogenous city formation. Thus, this result provides formal support for the conjecture that production externalities lead to urban agglomeration.     

International Commodity Taxation under Monopolistic Competition

We analyze non‐cooperative commodity taxation in a two‐country trade model characterized by monopolistic competition and international firm and capital mobility. In this setting, taxes in one country affect foreign welfare through the relocation of mobile firms and through changes in the rents accruing to capital owners. With consumption‐based taxation, these fiscal externalities exactly offset each other and the non‐cooperative tax equilibrium is Pareto efficient. With production‐based taxation, however, there are additional externalities on the foreign tax base and the foreign price level that lead non‐cooperative tax rates to exceed their Pareto efficient levels.     

Interdependence and spillovers: is firm performance affected by others’ innovation activities?

The creation of new knowledge is a case in which agents' behaviour can affect the performance of other actors positively, given that new knowledge creates positive externalities in the market. In this context, we investigate the existence of performance spillovers associated with innovation activities by quantifying the innovation produced in surrounding firms and controlling for the fact that a firm is itself an innovation producer. We use data from the Third Community Innovation Survey (CIS III) that measures innovation in a broad way, not reducing it to R&D and patents, which departs from previous literature on spillovers. Furthermore, to tackle the endogeneity of the innovation variables on the firm production decision, we resort to the firm intellectual property protection methods as an instrument. We found a positive spillover of innovation on firm value added. The results also show that process innovation spillovers are more prevalent than product innovation spillovers.     

The joint effects of financial development and the business environment on firm growth: Evidence from Vietnam

This work examines the complementary effects of local financial development and the business environment on the growth of Vietnamese firms. For the period from 2009 to 2013, we combine firm-level data covering more than 40,000 firms from the Vietnam Enterprise Survey with province-level data from the Vietnam Provincial Competitiveness Indicators. Our estimation strategy builds upon a novel copula-based estimator that accounts for potential endogeneity biases without requiring external instruments. Our results show that financial development and a favourable business environment generally promote firm growth, but some components of the business environment, such as low entry costs, access to land and business service support, foster firm growth more strongly than financial development. Most importantly, financial development and the business environment interact positively in their effects on firm growth. The impact of local financial development on firm growth is higher in provinces with a competitive business environment. Conversely, improvements in provincial competitiveness have a greater impact on firm growth in provinces with a more developed financial sector. The results clearly show that policies to promote local financial development need to be coordinated with measures to improve the broader business environment.     

Trade, regulations, and income

We examine the relationship between openness and per-capita income using cross-country data from 126 countries. We find that trade leads to a higher standard of living in flexible economies, but not in rigid economies. Business regulation, especially on firm entry, is more important than financial development, higher education, or rule of law as a complementary policy to trade liberalization. Specifically, after controlling for the standard determinants of per-capita income, our results imply that a 1% increase in trade is associated with more than a one-half percent rise in per-capita income in economies that facilitate firm entry, but has no positive income effects in more rigid economies. The findings are consistent with Schumpeterian “creative destruction”, which highlights the importance of new business entry in economic performance, and with previous firm-level studies showing that the beneficial effects of trade liberalization come largely from an intra-sectoral reallocation of resources.     

Embedding environmental innovation in local production systems: SME strategies,networking and industrial relations: evidence on innovation drivers in industrial districts

Technological innovation is a key factor for achieving better environmental performances. Its role is even more relevant in local productions system, where innovation density, knowledge spillovers and externalities are concentrated in a circumscribed territory. The paper exploits new data for a sample of manufacturing firms in Northern Italy. New evidence is provided by testing a set of hypotheses, concerning primarily the role of environmental‐devoted R&D, networking activities, quality/nature of industrial relations. The role played by environmental policy pressure, structural firm features and past firm performances is also investigated to account for more exogenous forces. We show that structural characteristics of the firm appear to matter less than R&D, induced policy costs and innovative‐oriented industrial relations. Environmental auditing schemes also show some relevant correlation to innovation adoptions. R&D efforts appear to be associated to networking activities, which substitute for size‐related economies of scale. Overall, endogenous factors driven by firm strategy or local idiosyncratic features matter more than exogenous and structural firm factors.     

商业模式创新、技术创新与企业绩效关系:基于创业板上市企业的实证研究

商业模式创新、技术创新都是企业提升竞争力和绩效的重要手段。以58家创业板上市企业为样本,对商业模式创新与企业绩效的关系、技术创新与企业绩效的关系以及商业模式创新与技术创新的交互作用进行了研究。结果发现:商业模式创新只对企业营业收入增长具有显著的正向影响,技术创新只对企业利润增长具有显著的正向影响,而商业模式创新与技术创新是互补关系,二者的交互对企业绩效(营业收入增长、利润增长)具有显著的正向影响。这些结果表明,对于企业特别是类似于在创业板上市的科技型中小企业来说,商业模式创新与技术创新对于企业绩效的贡献是不同的,只有综合推进商业模式创新与技术创新并形成互补关系,确保商业模式创新和技术创新完全成功,才能全面提升企业绩效。     

The firm as a subeconomy

This article explores the economic role of the firm in a marketeconomy. The analysis begins with a discussion and critiqueof the property rights approach to the theory of the firm asexposited in the recent work by Hart and Moore ('Property Rightsand the Nature of the Firm'). It is argued that the Hart-Mooremodel, taken literally, can only explain why individuals ownassets, but not why firms own assets. In particular, the logicof the model suggests that each asset should be free standingin order to provide maximal flexibility for the design of individualincentives. These implications run counter to fact. One of thekey features of the modern firm is that it owns essentiallyall the productive assets that it employs. Employees rarelyown any assets; they only contribute human capital. Why is theownership of assets clustered in firms? This article outlinesan answer based on the notion that control over physical assetsgives control over contracting rights to those assets. Metaphorically,the firm is viewed as a miniature economy, an 'island' economy,in which asset ownership conveys the CEO the power to definethe 'rules of the game', that is, the ability to restructurethe incentives of those that accept to do business on (or with)the island. The desire to regulate trade in this fashion stemsfrom contractual externalities characteristic of imperfect informationenvironments. The inability to regulate all trade through asingle firm stems from the value of exit rights as an incentiveinstrument and a tool to discipline the abuse of power.     

Technology, agglomeration, and regional competition for investment

Abstract.  Competition for firms by region has a long-standing history, and the academic literature has debated whether such competition is efficient. We develop a model that explores technology development by firms facing regional competition for their investment and examine the endogenous determination of region policy, firm technology, and agglomeration externalities. We find a new source of inefficiency – regional competition leads firms to inefficiently distort their development and selection of production technology to improve their standing in the regional competition for their investment. We show that these inefficient firm decisions on technology and location can also weaken agglomeration externalities.

Temporary shocks and offshoring: The role of external economies and firm heterogeneity

We construct a model of offshoring with externalities and firm heterogeneity. Due to the presence of externalities, temporary shocks like the Y2K problem can have permanent effects, i.e., they can permanently raise the extent of offshoring in an industry. Also, the initial advantage of a country as a potential host for outsourcing activities can create a lock in effect, whereby late movers have a comparative disadvantage. Furthermore, the existence of firm heterogeneity along with externalities can help explain the dynamic process of offshoring, where the most productive firms offshore first and the others follow later. Finally, we work out some unexpected welfare implications which show that net industry profits can be lower in an outsourcing equilibrium than in a regime of no outsourcing. Consumer welfare rises, and under fairly plausible conditions this effect can offset the negative impact on profits.
