Innovation and trade with heterogeneous firms

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. Among the robust results that hold both in the short run when there is no entry, and in the long run under free entry are that trade liberalization increases aggregate R&D when trade costs are low and decreases R&D when trade costs are high. Expected industry productivity rises as trade costs fall.     

Entry,trade costs,and international business cycles

Are firm entry and fixed exporting costs relevant for understanding the international transmission of business cycles? We revisit this question using a model that includes entry, selection to exporting activity, physical capital accumulation and endogenous labor supply. We determine that once the stochastic process for exogenous productivity is calibrated to consider the endogenous dynamics in TFP created by the number of firms and the time series volatility of entry is calibrated to the data, our model yields minimal departures from the Backus et al. (1992) benchmark. The richer model shares all of the successes of the previous model in terms of the volatilities of aggregate quantities, as well as its failures, in terms of replicating patterns of international co-movement and the volatility of international relative prices.

The dynamics of entry,exit and profitability: An error correction approach for the retail industry

We develop a two equation error correction model to investigate determinants of and dynamic interaction between changes in profits and number of firms in retailing. An explicit distinction is made between the effects of actual competition among incumbants, new firms competition and potential competition from firms outside the market. Effects of cost, demand and general income changes on profitability are investigated to gain insight in the role of retailing in the cost, demand and wage inflationary processes. The relative importance of profitability, growth and unemployment as determinants of net entry are studied. The model is tested using a panel data set of 36 Dutch shoptypes covering the 1977–1988 period.     

HYSTERESIS IN THE DYNAMICS OF EMPLOYMENT

In this paper, we derive a micro model of employment demand with hysteresis whereby firms can adjust along an intensive (employment) and an extensive (hours of work) margin. A mechanism of aggregation over heterogeneous firms is used to generate the corresponding aggregate dynamics. Longitudinal micro monthly data on a representative sample of Portuguese manufacturing firms are used in the empirical analysis. Our results indicate that signs of hysteresis found at the micro level do not vanish completely by aggregation and that hysteresis is magnified by the existence of an additional margin of adjustment (the hours adjustment margin).     

Asymmetric Collusion with Growing Demand

We characterize collusion sustainability in markets where demand growth triggers the entry of a new firm whose efficiency may be different from the efficiency of the incumbents. We find that the profit-sharing rule that firms adopt to divide the cartel profit after entry is a key determinant of the incentives for collusion (before and after entry). In particular, if the incumbents and the entrant are very asymmetric, collusion without side-payments cannot be sustained. However, if firms divide joint profits through bargaining and are sufficiently patient, collusion is sustainable even if firms are very asymmetric.     

SEARCH UNEMPLOYMENT AND THE EFFECT OF AGGREGATE DEMAND POLICY: A DUAL LABOR MARKETS ANALYSIS

This paper examines the role of aggregate demand policy affecting unemployment under a model of dual labor markets. Recently, some papers have considered the sources of unemployment in OECD countries and have stressed the role of aggregate demand policy in reducing it. However, there exists the argument that aggregate demand policy may have an adverse effect on unemployment. Therefore, in this paper, we will consider in what situations aggregate demand policy has such an effect on unemployment, and propose an analysis of its microfoundation.     

THE DIAMOND OF MACROECONOMIC EQUILIBRIA AND NON‐INFLATIONARY EXPANSION

This paper combines the microeconomic foundations of earlier models of a range of equilibrium rates of employment to generate a model with a diamond of equilibria. Analysis of the diamond model shows that for a depressed economy an expansionary aggregate demand policy can, without violating rational expectations of inflation, generate a central proposition of Keynesian economics—a non‐inflationary expansion (NIE), that is a permanent increase in employment without increasing inflation. The microeconomic foundations of the model draw on ideas of customer markets, reference dependence and loss aversion. It is also shown that the possibility of achieving an NIE is enhanced if a macro price policy, such as incomes policy or inflation targeting, accompanies the expansion in aggregate demand.     

Competing with multinational enterprises’ entry: Search strategy,environmental complexity,and survival of local firms

This study examines the competitive dynamics between foreign and local firms. We posit that multinational enterprises (MNEs)’s entry in foreign markets significantly reduces the survival rate of local firms in the short term, but that this effect gradually diminishes over time. The proposed conceptual framework is operationalized through the combination of the widely used agent-based model and the economic model of competition. The agent-based model allows us to study the behavior of firms under the context of different markets and the environmental complexity while the competition model determines the competition between firms as well as the entry and exit of firms. Our results obtained from the simulation study reveal that the negative effect of foreign entry is heightened as environmental complexity increases. However, local firms with a broader knowledge search are better able to confront the negative impact of foreign entry over time. We also find that the negative effect of foreign entry on the survival of local firms is weaker for local firms with a strong retrieval capacity.     

The Property Rights Theory of the Firm and Mixed Competition: A Counter-Example in the US Health Care Industry

We present a counter-example to the conventional property rights theory of the firm, which indicates that not-for-profit firms are incapable of directly competing against strictly profit-maximizing firms without the presence of barriers to entry, outside assistance, changing profit status or economies of scale and scope. We employ a modified Bertrand duopoly model of mixed competition in the health care industry to show that, even when these four conditions do not hold, not-for-profit firms may still be able to compete and possibly dominate the market. Consequently, market fundamentals, rather than market intervention, regulation or uncertainty, determine a not-for-profit provider's success or failure in the market. A necessary requirement is that the not-for-profit manager must care about non-pecuniary benefits but be willing to accept lower than normal returns. Moreover, under specific cost and demand conditions, a not-for-profit's ability to compete may actually be enhanced by increasing its production of non-pecuniary benefits.     

On the Differential Behaviour of National and Multinational Firms: A Within‐ and Across‐sectors Approach

This paper looks for different patterns of behaviour of national firms and multinational enterprises (MNEs). Its main contribution is the use of a computable general equilibrium perspective to analyse firms’ performance. The model is calibrated for the case of the Czech Republic, which has been a very attractive foreign direct investment location in the last three decades. We replicate the arrival of MNEs to different sectors of this country in turn and analyse the responses of both types of firms across the 20 different sectors in which the Czech economy has been split. Our results grasp the short‐run impact. The higher labour intensity of national firms leads them to different patterns of production and labour demand, compared with MNEs operating within the same sector. The demand side of the model (particularly, exports and private consumption) drives the evolution of production and labour demand across sectors. Regarding prices, we also find a differential pattern between both types of firms within and across sectors. Our analysis offers detailed evidence on how the impact of MNEs will differ depending on the sector to which they arrive. Finally, the aggregate results suggest that a completely different microeconomic panorama may underlie rather similar macroeconomic outcomes.     

Product Quality,Cost Asymmetry and the Welfare Loss of Oligopoly

When competition is tough, firms which do not implement the least expensive technology are forced to exit, or the low cost firms are able to increase their market share. Persistent cost or profit differences require some form of restricted entry, specific intangible assets or oligopolistic co-ordination. If technology or skills is easy to transfer but it is not transferred because of collusion, we have to add a cost side effect ('the staircase')stemming from the non-proliferation of the best technology- to the well-known demand side loss ('the triangle'). This paper presents a model with vertical product differentiation and develops a method which disentangles cost differences coming from vertical product differences and those coming from other sources. Data for the paper industry in the EU, in the US and in Japan indicate that cost differences are large. If at least some part of them comes from oligopolistic co-ordination, then the welfare loss of oligopoly is much larger than the usually measured demand side welfare loss.     

THE PROFIT–INVESTMENT–UNEMPLOYMENT NEXUS AND CAPACITY UTILIZATION IN A STOCK‐FLOW CONSISTENT MODEL

This paper studies under which conditions the share of profit in value‐added, financial constraints on investment and capital shortage may foster unemployment and may limit the growth of capital and/or the growth of aggregate demand, in a stock‐flow consistent model. The efficiency of demand‐side versus supply‐side economic policies (decrease of the real interest rate and/or of the real wage, increase of the leverage ceiling constraint) depends on capital shortage and credit rationing, which are not necessarily simultaneous due to the effects of investment on aggregate demand and supply.     

Networks,firms, and trade

Fixed costs associated with learning about demand and setting up distribution networks are expected to be lower when there are more potential contacts in the destination market, suggesting a greater probability of market entry and larger export revenues. We match historically-determined emigration stocks with detailed firm-level data from Portugal to examine the effect of migrant networks on these export outcomes. We find that larger stocks of emigrants in a given destination increase export participation and intensity. In addition, we show that the former of these effects tends to be more pronounced among firms that are more likely to have close ties with the emigrants. These results are consistent with a multiple-destination version of the Melitz (2003) model featuring market-specific entry costs and idiosyncratic firm-destination demand shocks.     

The quality of innovation and the extent of the market

I present a comprehensive model of international trade in technology that considers both the demand for inventions and the supply of inventions. On the demand side, domestic and foreign firms make strategic technology adoption decisions. On the supply side, inventors compete to sell licenses for their technology to domestic and foreign firms. Countries benefit from international trade in technology because they obtain the best invention from a larger pool of inventions. International trade in technology increases the extent of the market for inventions and thereby improves the quality of innovation. Technology trade lowers prices, increases outputs, and increases the volume of trade in differentiated products. When traded products are not close substitutes, international markets for technology generate gains from trade. The results of the analysis are robust to the possibility of technology transfer either through expropriation or imitation. Protection of intellectual property rights preserves incentives for entry of inventors and improves the quality of innovation.     

Linking net entry to regional economic growth

Regional growth differentials could be explained by how intensively and dynamically new firms of a particular region enter expanding industries. Although the direct contribution of new firms to value creation and growth may be regarded as tautological, the aggregate impacts are largely empirically unobserved. After a brief motivation, we use an expression of firm net entry as an indicator of the distinctive capacity of regional entrepreneurial resources to enter new industries and create value. Using data for Belgian districts, we test the net entry effects on subsequent economic growth in the manufacturing and services industries. Our analysis helps emphasize the different dynamics at work within the manufacturing and services industries and, although requiring cautious interpretation, provides evidence for some positive impact of net entry on regional economic growth in the services industry.     

International Competition and Distributive Class Conflict in an Open Economy Kaleckian Model

This paper constructs an open economy Kaleckian model in which international competition affects the bargaining process between firms and workers, and investigates the effects of such bargaining on the macroeconomy. We show that the effects of a change in the bargaining power on aggregate demand depends not only on the demand regimes but also on which agents bears more of the burden arising from the international price competition. Moreover, if the real exchange rate has a small impact on the trade balance, the economy is stable, whereas if it has a larger impact on the trade balance, the economy is unstable.     

Business models and market entry mode choice of small software firms

So far the critical choice of the entry mode for a target country has been examined ignoring the special features of firms. Particularly, the impact of the wide variation of business models of software firms has been ignored. This multi case study investigates the relation between the business model and the entry mode, of eight software firms. The results imply that the product strategy and the service and implementation model of a software firm are closely connected to the entry mode choice, while the distribution model of intangible software products does not seem to have an impact on the operation mode.     

MONOPOLISTIC COMPETITION AND SEARCH UNEMPLOYMENT

In this paper the monopolistic competition model of Dixit and Stiglitz for the goods market and the search unemployment model of Pissarides are combined. The Pissarides part loses its Walrasian goods market and the Dixit–Stiglitz part loses its Walrasian labour market. Pissarides’ results now depend on the degree of competition. In the Dixit–Stiglitz part the size and number of firms as well as aggregate output now depend on aggregate hiring costs, tightness and unemployment, while real wages are not fixed. Some partial results of comparative static properties of the original models survive. New results concerning the effects of changes in labour (goods) market parameters on goods markets (the labour market) variables are obtained and related to the literature on macroeconomic theory with endogenous unemployment and imperfect competition, empirical results and policy issues.     

Learning to export: Export growth and the destination decision of firms

I find evidence that the geographic expansion of firm exports occurs slowly over time and that a large share of export growth is due to incumbent exporters entering new destinations. New exporters enter large countries and destinations with characteristics similar to their domestic market. Less similar, distant or less developed countries are entered by firms already exporting to other destinations. I formulate a dynamic general equilibrium model to test if these patterns are due to firms learning how to export (as other recent empirical findings have suggested) or other factors considered in the literature. In this model, heterogeneous firms experience learning in the form of market entry costs that depend on export history. Using Russian firm level data, I find that learning plays a significant role in explaining the observed entry patterns, which standard trade models cannot account for.
