The Persistence of Profits,Sectoral Heterogeneity and Firms’ Characteristics

The analysis of the persistence of profits has long been a controversial issue within empirical industrial organisation literature. The aim of our paper is to provide new empirical findings that may account for patterns of both sectoral and firm profit persistence. The distinctive feature of our study is that we analyse a number of firms’ ergodic distribution in each sector according to their profit level; we then calculate the difference between such a distribution and that prevailing in manufacturing as a whole. Finally, we break down this distribution; the resulting breakdown highlights the impact of each transition probability on inter‐sectoral differences clearly, and it also emphasises the role of intra‐sectoral dynamics in determining different persistence patterns. We then apply this methodology to both innovating and non‐innovating firms, and conclude that among surviving firms innovation is indeed crucial to the persistence of profits. In addition, we set up an econometric test which enables us to estimate the impact of firm and sectoral characteristics on a firm’s profit condition.     

Competition for firms in an oligopolistic industry: The impact of economic integration

We set up a model of generalised oligopoly where two countries of different size compete for an exogenous, but variable, number of identical firms. The model combines a desire by national governments to attract internationally mobile firms with the existence of location rents that arise even in a symmetric equilibrium where firms are dispersed. As economic integration proceeds, equilibrium taxes initially decline, but then rise again as trade costs fall even further. A range of trade costs is identified where economic integration raises the welfare of the small country, but lowers welfare in the large country.     

International trade,risk taking and welfare

This paper shows that the gains from opening up to international trade are smaller when firms do not fully internalize downward risk. I develop a general equilibrium model with two key assumptions. First, when faced with adverse productivity shocks, employers can lay off workers without fully paying the social costs of their layoff decisions, a common feature of many institutions. Second, when opening to international trade, the elasticity of demand perceived by an industry increases. In this setup, I show that international trade induces firms to take more risk and (i) raises the equilibrium unemployment rate, (ii) increases the volatility of sectoral sales and (iii) increases welfare proportionately less than in the absence of the externality. Inducing firms to internalize the costs of layoff (Blanchard and Tirole, 2003) therefore appears even more important in a globalized world.     

Entry and exit in disequilibrium

Most entrepreneurship theory depicts disequilibrium as the most common state for entrepreneurial activity and yet remarkably very little empirical research investigates the role of entry and exit in this type of external environment. Drawing on economics and organizational ecology we outline reasons why the interrelation between entry, exit and incumbent firms is likely to vary when the actual number of firms is higher or lower than the number that a market can sustain. We also introduce a new empirical methodology to explain entry and exit levels in two different types of disequilibria comprising situations when markets under and over shoot carrying capacity. Using a data set on the retail industry, we find that in undershoots a lack of competition between incumbent firms restores equilibrium by creating room for new-firm entry. In contrast, in overshoots competition induced by new firms (in particular strong displacement) restores equilibrium. We also find that equilibrium-restoring mechanisms are faster in over than undershoots. The results highlight that the behaviour and impact of entry and exit varies depending on the type of disequilibrium.     

Capital controls and the location of industry

This paper studies capital controls on the outflow of capital in a two-region new economic geography model. Capital controls are set in a non-cooperative or cooperative manner by social planners. Capital controls are relatively higher in the North in the non-cooperative equilibrium. This leads to relatively more firms located in the region where more consumers reside under the non-cooperative equilibrium. The locational bias towards the North in the non-cooperative equilibrium becomes larger as trade barriers are reduced. That is, firms locate to the North at a relatively higher rate in the non-cooperative equilibrium as trade is liberalised. Contrary to previous findings, it follows that global welfare is relatively higher in the non-cooperative equilibrium, although the social planner sets capital controls by maximising joint regional welfare in the cooperative equilibrium.     

Optimal Utilization of Capital and a Financial Sector in a Classical Gravitation Process

In a production price framework, a two‐sectoral gravitation process with cross‐over adjustments of prices and quantities is advanced. To overcome an inconsistency in the treatment of fixed capital in disequilibrium, the socio‐technological input coefficients are assumed to vary with the sectoral output–capital ratio, such that for each relative price there exists an optimal degree of capital utilization which maximizes the sectoral rate of profit. Production prices prevail if these maximizing rates of profit are equalized. In addition, a financial sector determining the rate of interest is incorporated into the model. The mathematical analysis establishes a broad scope for local stability of the long‐run equilibrium position once a condition applies that ensures stability of the output adjustments in the short period.     

Location choice of academic entrepreneurs: Evidence from the US biotechnology industry

Where knowledge-based firms are located is important because entrepreneurship, firm creation and innovation are typically associated with regional economic development, wealth creation and increased employment. In this paper we examine where academic entrepreneurs locate their firms. We begin by developing a theoretical model that examines the location choice of the academic entrepreneur within the standard utility maximization theory. Academic entrepreneurs are assumed to maximize their utility by allocating their efforts between academic and entrepreneurial pursuits which, in turn, determine their future streams of income and end-period wealth. Optimal allocation turns out to be a function of both personal and external factors that condition the relevant payoffs and such factors can be empirically observed. We then use several candidate explanatory variables to examine those factors that may influence the firm location choice for 187 biopharmaceutical firms started by 275 academic entrepreneurs in the US. From our empirical analysis we find that location-specific factors such as proximity to certain knowledge assets and to the funding venture capital firms, affect the firm location choice of academic entrepreneurs. Nevertheless, entrepreneur-specific characteristics, such as their age, seem to dominate the choice of firm location.     

Province-Level Impacts of Canada’s Trade Agreements

Given Canada’s extended geography and regional economic diversity, individual provinces have differing exposures to particular international trade agreements. We demonstrate this by estimating the impacts of the Canada-Korea free trade agreement on the province of Ontario, using a dynamic general equilibrium model to generate Canada-level impacts, which are then decomposed on the basis of partial equilibrium model simulations on a trade dataset in which Ontario is represented as a separate international trading entity. We show that geography and sectoral specialization matter and that general equilibrium effects must be taken into account in partial equilibrium assessments of sectoral impacts of major trade agreements.     

The cities/services-nexus: determinants of the location dynamics of advanced producer services firms in global cities

This paper presents an analysis of the determinants of the location dynamics of advanced producer services firms in global cities. By gauging the importance of the presence of leading firms for the years 2000 and 2004, a measurement of the aggregate location change is produced. This measure is used to search for determinants of the observed location change, both in general and in sectoral terms (management consultancy and banking). We also investigate how the presence of firms from the same and from other sectors influences the dynamics of a firms' location strategy.     

Wage bargaining and multinational firms

We set up a general equilibrium model with heterogeneous firms to study the interaction between wage bargaining and foreign direct investment. Thereby, we highlight the incentives of firms to invest abroad in order to improve their bargaining position vis-á-vis local unions and we show how changes in the bargaining power of unions affect the share of multinational firms in an open economy. In addition, taking into account this relationship between wage bargaining and foreign direct investment, our analysis provides novel insights on how labor income and the unemployment rate adjust to economic integration and how changes in the bargaining power of unions affect these two labor market variables.     

A simple model of firm heterogeneity, international trade, and wages

This paper presents a general equilibrium trade model in which homogeneous firms choose a technology from a set of competing technologies and choose employees from a set of workers of heterogeneous skill. In equilibrium, the interaction between the characteristics of competing technologies, international trade costs, and the availability of workers of heterogeneous skill gives rise to firm heterogeneity. The model generates several of the stylized facts concerning the (apparent) superiority of firms that engage in international trade relative to those that do not and has implications for the effect of international trade on the skill premium and on observed industry-level productivity.     

环境规制的“灰边”效应

本文基于“中心—外围”经济空间结构框架,在理论层面演绎了城市间环境规制强度级差对污染企业区位选择策略的影响,并基于2005—2012年京津冀地区微观企业具体的选址设厂地理信息,以北京市行政区划边界为断点对污染企业二氧化硫排放的空间分布特征进行了实证分析。理论演绎表明,在环境规制离心力和成本节约、市场需求潜力向心力等因素的共同作用下,污染企业最终将聚集在环境规制强度级差边界选址设厂,从而形成环中心城市的污染“灰边”。通过对6000余家污染企业共计18000余个有效观测值的回归研究发现,环北京市行政区划边界50公里范围内为污染物高排放带,改变估计参数、更换代理变量、删除特殊样本等一系列检验均证明了“灰边”效应稳健存在。北京市东部地区“灰边”效应的表现最为明显,非国有性质污染企业的高度聚集是形成环北京市污染物高排放带的主要原因。2008年北京奥运会及之后的一段时间,“灰边”效应曾随着外围城市污染企业关停力度的加大暂时消失,但2010年之后环北京市的污染“灰边”再度出现。本文将环境规制因素纳入区位选择理论分析框架,为“中心—外围”城市间联防联控进行污染治理的必要性提供了新的理论解释和实证依据。     

Internal and external gains from international outsourcing

This article examines the implications of international outsourcing in the Heckscher–Ohlin model of general equilibrium by explicitly expounding the external effects to the outsourcing firms. With its focus paced on the labor-augmenting effect of outsourcing, it shows that (a) the standard result of welfare-enhancing outsourcing always holds in the absence of external effects, and (b) in the presence of external effects, however, (i) outsourcing may be welfare-reducing for the outsourcing country; (ii) the effects of outsourcing on sectoral outputs, employment and factor prices depend on factor-intensity ranking, and the signs and the relative magnitudes of the sectoral returns to scale.     

Real Exchange Rate Targeting,Macroeconomic Performance and Sectoral Income Distribution in Developing Countries

This paper uses a two-sector general equilibrium model to analyse both steady-state and stochastic dynamic effects of two real exchange rate targeting policies: a constant-target, and a band-target rule. In the model, targeting is implemented by imposing a stochastic fully-rebatable tax on the consumption of non-traded goods. The first result is that when comparing only steady states, a real exchange rate appreciation favours labour and capital in the non-traded sector, while factors in the traded sector are favoured by depreciations. A second result is that both rules reduce the volatility of investment and the trade balance. The third key result is that in the stochastic economy sectoral income distribution outcomes depend on the design of the constant and band-target rules. In particular, a variety of outcomes may be generated depending on the magnitude of the constant target, or the amplitude of the band, relative to the volatility of productivity shocks.     

Knowledge spillovers and high-impact growth: Comparing local and foreign firms in the UK

This paper is concerned with entrepreneurial high-impact firms, which are firms that generate ‘both’ disproportionate levels of employment and sales growth, and have high levels of innovative activity. It investigates differences in the influence of knowledge spillovers on high-impact growth between foreign and local firms in the UK. The study is based on an analysis of data from UK Innovation Scoreboard on 865 firms, which were divided into ‘high-impact firms’ (defined as those achieving positive growth in both sales and employment) and low-impact firms (negative or no growth in sales or employment). More precisely, the paper investigates the influence of knowledge spillovers on high-impact growth of foreign and local firms, from regional, sectoral and firm size perspectives. The findings suggest that (1) firms’ access to regional knowledge spillovers (from businesses and higher education institutions) is more significantly associated with high-impact growth of local firms in comparison to foreign firms; (2) because knowledge spillovers are more likely to occur in high-tech sectors (compared to low-tech sectors), firms in high-tech sectors are more associated with high-impact growth. Nonetheless, the relationship is stronger for local firms compared to foreign firms; (3) because small firms have greater need for knowledge spillovers (relative to large firms), there is a negative relationship between firm size and high-impact growth, but the negative relationship is greater for UK firms in comparison to foreign firms. Implications are drawn for policy and research.     

Exports versus multinational production under nominal uncertainty

This paper examines how nominal uncertainty affects the choice that firms face to serve a foreign market through exports or to produce abroad as a multinational. I develop a two-country, stochastic general equilibrium model in which firms make production and pricing decisions in advance, and I consider its implications for the relative attractiveness of exporting and multinational production. I find that when multinational sales are priced in the local currency while exports are priced in the producer currency, destination volatility benefits exporters: during a foreign nominal contraction, the foreign exchange rate appreciates, causing exports to be relatively cheaper. Exporters gain non-linearly through demand, making profit convex in prices. As foreign volatility rises, the model implies that the home country should serve the foreign country relatively more through exports. I take this implication to bilateral U.S. data, using inflation volatility as a proxy for nominal volatility. Using sectoral data on sales by majority-owned foreign affiliates matched with U.S. exports, I find that higher inflation volatility is associated with a significantly lower ratio of multinational sales to total foreign sales.     

Strategic Investment Decisions under Uncertainty,Tacit Collusion and Product Differentiation

This paper examines the effects of uncertainty, tacit collusion and product differentiation on strategic investment policy. The model demonstrates the equilibrium under competitive investments and under cooperative investments. In competitive investments, two firms compete by investing to preempt each other, and ultimately one firm invests earlier than its rival. In cooperative investments, two firms invest simultaneously and collude on their outputs. Cooperative investments are likely to be sustainable only under conditions of high volatility of future demand, low probability of market extinction and high degree of product differentiation, while competitive investments are sustainable for any set of these parametric values.

Business Conditions and Business Starts

This paper analyses the effect of business conditions on new firm starts. The birth of new firms displays a pro-cyclical behaviour, more firms being created when GDP is growing fast and the interest rate is low. The entry response to industry profitability is tempered by the level of sunk costs; for a given profit signal, more entry occurs where sunk costs are low.     

A theory of the currency denomination of international trade

The currency denomination of international trade has significant macroeconomic and policy implications. In this paper we solve for the optimal invoicing choice by integrating this microeconomic decision at the level of the firm into a general equilibrium open economy model. Strategic interactions between firms play a critical role. We find that the less competition firms face in foreign markets, as reflected in market share and product differentiation, the more likely they will price in their own currency. We also show that when a set of countries forms a monetary union, the new currency is likely to be used more extensively in trade than the sum of the currencies it replaces.
