Price and Quantity Competition in a Differentiated Duopoly With Network Compatibility Effects

We consider the efficiency of price and quantity competition in a network products market, where we observe product compatibility with network externalities (hereafter, network compatibility effects). In particular, if network compatibility effects between firms are sufficiently asymmetric, the Cournot equilibrium is more efficient than the Bertrand equilibrium in terms of larger consumer, producer and total surpluses. Then, we consider an endogenous choice of the strategic variables, price and quantity. If the degree of network compatibility effects of the rival firm is larger (smaller) than the degree of product substitutability, then choosing prices (quantities) is a dominant strategy for the firm. Thus, if the network compatibility effects of both firms are larger (smaller), the Bertrand (Cournot) equilibrium arises. Furthermore, if the network compatibility effects between the firms are sufficiently asymmetric, the firm with a larger (smaller) network compatibility effect than a certain level of product substitutability chooses quantities (prices). In this case, the Cournot–Bertrand equilibrium arises, which is less (more) efficient than the Cournot equilibrium in terms of consumer (producer) surplus.     

The nonlinear effects of firm size on innovation: an empirical investigation

ABSTRACT

In conventional studies, large firms tend to emphasize more on process innovation than product innovation. This paper explores factors that could indicate a distinct pattern of firms’ innovation-size relationship: threshold size that implies a positive effect of firm size on the probability of product innovation success; cannibalization effect that creates incentives for large firms to favor product innovations; and financial constraints that have differential effects given different firm sizes. A hypothesis about a non-monotonic relationship between the proportion of product innovation and firm size is tested with nonlinear and dynamic econometric models. For the large firms, empirical evidence shows product innovations result in an overall larger share of new products in total sales, relative to existing products in which process innovations are rooted.     

Chinese competition and product variety of Indian firms

Using detailed firm-product-year data across manufacturing industries in India, and exploiting the exogenous nature of China’s entry into the WTO in 2001, we investigate the link between the impact of import penetration from China on the product variety of Indian manufacturing firms. We find: (i) robust and significant effects of product drop, with the effect coming only from competitive pressure in the domestic market; (ii) robust evidence of product drop or ‘creative destruction’ only for firms belonging to the lower-half of the size distribution; (iii) firms drop their peripheral/marginal products and concentrate on the core ones; and (iv) the result is strongest for firms producing intermediate goods. For an average Indian manufacturing firm, a 10 percentage point increase in India’s Chinese share of imports in the domestic market reduces the product scope of firms by 1.7–4.4%. In contrast, we find positive effects on product scope when firms are importing intermediate goods. We also find evidence of significant productivity effects and within-firm factor reallocation. Our results are consistent to a battery of robustness checks and IV estimation.     

Drivers of price reaction to rights issue announcements in the Kuwait Stock Exchange

This study examines the drivers behind stock price reactions to announcements of rights issues by firms listed on the Kuwaiti Stock Exchange for the period 2003–2013. We find higher cumulative abnormal returns for firms that undertake larger issues, with the issue size reflecting the availability of favourable investment opportunities and their potential positive impact on firms’ earnings. We also document a positive price reaction in firms that are affiliated with a family group. We interpret this as evidence that the proceeds of the rights offering would be employed effectively when the firm is controlled by a family firm. No evidence was found for the price pressure and pricing effects.     

Information Technology As A Factor Of Production: The Role Of Differences Among Firms

Despite evidence that information technology (IT) has recently become a productive investment for a large cross-section of firms, a number of questions remain. Some of these issues can be addressed by extending the basic production function approach that was applied in earlier work. Specifically, in this short paper we: 1) control for individual firm differences in productivity by employing a ‘firm effects’ specification, 2) consider the more flexible translog specification instead of only the Cobb-Douglas specification, and 3) allow all parameters to vary between various subsectors of the economy.

We find that while ‘firm effects’ may account for as much as half of the productivity benefits imputed to IT in earlier studies, the elasticity of IT remains positive and statistically significant. We also find that the estimates of IT elasticity and marginal product are little-changed when the less restrictive translog production function is employed. Finally, we find only limited evidence of differences in IT's marginal product between manufacturing and services and between the ‘measurable’ and ‘unmeasurable’ sectors of the economy. Surprisingly, we find that the marginal product of IT is at least as high in firms that did not grow during 1988–1992 sample period as it is in firms that grew.     

Empirical Patterns of Firm Growth and R&D Investment: a Quality Ladder Model Interpretation

We present a partial equilibrium model of endogenous firm growth with R&D investment and stochastic innovation as the engines of growth, drawing on the quality ladder models in the macro growth literature, and the literature on patent races and the discrete choice models of product differentiation. The model fits a number of empirical patterns well, including: (i) a skewed size distribution of firms with persistent differences in firm sizes, (ii) firm growth independent of firm size, as stated in the so-called Gibrat's law, and (iii) R&D investment proportional to sales.     

Informal incentive labour contracts and product market competition

This paper studies the dynamic interaction between product market competition and incentives against shirking. In contrast with standard results, efficiency wages paid by each firm can decrease when competition (i.e. the number of firms in the product market) increases. Discretionary bonuses, on the other hand, do not vary with competition. There is an upper threshold for the number of competing firms, however, above which such schemes are no longer sustainable as an equilibrium. Industry profits with bonuses are generally higher than with efficiency wages but, when information regarding firms’ misbehaviour flows at a low rate, a competition range exists for which firms can make a positive profit by only paying efficiency wages.     

Going offshore or better staying in? Spatial relocation strategies and their impact on firm innovativeness

We analyse the short- to mid-run effects of spatial relocation strategies on firm innovativeness and productivity growth. Using conditional difference-in-difference estimation with multiple treatments, we find for a sample of German firms in 1999–2013 that offshoring has a statistically significant negative impact on the firms’ innovation activity and productivity growth vis-à-vis nonrelocating comparison firms. In contrast, we find a positive link between domestic relocation activities and the firms’ propensity to introduce a product innovation. Firms should thus carefully account for potentially distorting performance effects when deciding about the spatial scale of relocation strategies in the short to mid-run.     

Price competition and quality differentiation with multiproduct firms

This paper examines a two-stage competition where firms simultaneously choose the number of products and qualities in the first stage, and then compete in prices. It is shown that a monopolist must sell a single product. In addition, in any equilibrium of multiproduct duopoly, there are segmented patterns of quality differentiation. Entangled configurations never emerge because each firm has an incentive to reduce the number of products facing direct competition with its rival. This result contrasts sharply with the equilibrium of non-segmented quality differentiation when firms compete in quantities. Furthermore, we find that the high-quality firm never offers more products than the low-quality firm, and quality differentiation between firms is greater than that within a firm.     

Growth, Competition and Welfare

The impact of competition on growth and welfare is analysed by developing a model in which the number of firms, profit margins and innovation rates are endogenous. Different regimes of oligopolistic competition are distinguished. The tougher the price competition, the lower the profit margins for a given rate of concentration. This reduces the number of firms and product variety in a free entry equilibrium. Consequently, tougher competition implies larger firm size and higher rates of innovation since new technologies can be applied in a larger market. Oligopolistic pricing leads to underinvestment in firm-specific knowledge, even if inter-firm knowledge spillovers are neglected.     

Does trade stimulate product quality upgrading?

This paper investigates whether increased import competition leads firms to engage in incremental innovation reflected in product quality upgrading using Chilean manufacturing firm‐product data and measuring product quality with unit values (prices). We identify causal effects of import competition using an effective trade barrier measure – transport costs – as instruments for import penetration ratios across industries. Transport costs have a negative and significant effect on product quality. The evidence suggests that estimated unit value increases capture product quality upgrading, imports’ competition effects drive quality upgrading, and benefits depend on firms’ industrial specialization. Easier access to intermediate inputs also fosters quality upgrading.     

Does Openness Increase the Efficiency of China’s Manufacturing Firms? Evidence from the World Bank Investment Climate Survey

Based on the World Bank Investment Climate Survey, this paper investigates the openness effects on the efficiency of firms in China’s manufacturing industry using a two-step data envelopment analysis (DEA) approach. In the first step, the aggregate efficiency of open firms and non-open firms is compared in each sub-industry using a group-wise heterogeneous bootstrap procedure. The results show, at a 90% confidence level, that open firms are more efficient than non-open firms in four out of five sub-industries. Furthermore, in the second step, we employ the two-stage bootstrap DEA approach to more specifically evaluate the effects of openness on the efficiency of firms. The regression results show that three openness indicators (foreign capital, import and export) have strong positive effects on firms’ efficiency in China’s manufacturing industry. In addition, the results also suggest that a larger state share, larger firm size, and more capital stock are negatively related to the efficiencies of firms, while a firms’ learning and absorptive capacity is positively related to its efficiency.     

Tax Competition in Vertically Differentiated Markets with Environmentally Conscious Consumers

This paper analyses the effects of tax competition on environmental product quality, pollution and welfare in a two-country, vertically differentiated, international duopoly, in which consumers are environmentally conscious. The firm in each country chooses first the environmental quality of its product (which reflects the emissions generated in the production process) and then the price. In equilibrium one country will be more polluted than the other because firms choose different levels of environmental quality of their products. We find that a country’s optimal commodity tax is higher if the domestic firm is the more polluting supplier. Furthermore, non-cooperative commodity tax rates are inefficiently high in equilibrium. This is because, in this framework with environmentally aware consumers, commodity taxes affect the choice of firms regarding their emissions. Therefore, a domestic tax reduction not only raises the profits of the foreign firm but also lowers its emission levels, resulting in higher welfare for the other country. We also analyse the optimal cooperative and non-cooperative commodity and emission taxes with border tax adjustments. With these two policy instruments available, commodity taxes are higher.     

The effects of agglomeration economies on technical efficiency of manufacturing firms: evidence from Indonesia

This article examines the effects of agglomeration economies and industrial structure upon firm-level technical efficiency in the Indonesian manufacturing industry over the period 2004–2009. A stochastic production frontier and three channels of agglomeration economies consisting of specialization, diversity and competition are used. The empirical results show that the effects of specialization and diversity upon firm-level technical efficiency are positive and negative, respectively, indicating that specialization is more favourable than diversity for stimulating firms’ technical efficiency. Competition has a positive sign, showing that region with high levels of competition tend to be more conducive in accelerating firm-level technical efficiency. In terms of firm location, both dummy for urban region and industrial complex turn out to be positive, indicating that firms located in both areas are experienced higher technical efficiency. Both firm size and age also have positive effect upon technical efficiency.     

Choosing price or quantity? The role of delegation and network externalities

We consider a differentiated duopoly and endogenise the firm choice of the strategy variable (price or quantity) to play on the product market in the presence of network externalities. We model this choice by assuming both competition between entrepreneurial (owner-managed) firms and competition between managerial firms in which market decisions are delegated from owners to revenue-concerned managers. While network externalities are shown not to alter the symmetric equilibrium quantity choice arising in the no-delegation case, sufficiently strong network effects allow us to eliminate the multiplicity of equilibria under delegation and lead to a unique equilibrium in which both firms choose price.     

Niche products, generic products, and consumer search

We endogenize product design in a model of sequential search with random firm-consumer match value à la Wolinsky (Quart J Econ 96:493–511, 1986) and Anderson and Renault (RAND J Econ 30:719–735, 1999). We focus on a product design choice by which a firm can control the dispersion of consumer valuations for its product; we interpret low-dispersion products as “generic” and high-dispersion products as “nichy.” Equilibrium product design depends on a feedback loop: when reservation utility is high (low), the marginal customer’s match improves (worsens) with more nichy products, encouraging high (low) differentiation by firms. In turn, when firms offer more nichy products, this induces more intense search; depending on search costs, this could raise or lower consumers’ reservation utility. Remarkably, when the match distribution satisfies a hazard rate condition, firm and consumer interests align: equilibrium product design always adjusts to the level that maximizes utility. When this condition is not met, either multiple equilibria (one nichy, the other generic) or one asymmetric equilibrium (generic and nichy firms coexist) can arise; we argue that the former is more likely for common specifications of consumer preferences.     

FDI spillovers in new EU member states

Using an unbalanced panel of firm‐level data in Bulgaria, Poland and Romania, we examine the impact of foreign firms on domestic firms’ productivity. In particular, we try to answer the following research questions: (1) Are there any spillover effects of foreign direct investments (FDI), and if so, are they positive or negative? (2) Are spillover effects more likely to occur within or across sectors? (3) Are the existence, the direction and the magnitude of spillovers conditioned by sector and firm‐specific characteristics? Our findings show that FDI spillovers exist both within and across sectors. The former arise when foreign firms operate in labour‐intensive sectors, while the latter occur when foreign firms operate in high‐tech sectors. Moreover, we find that domestic firm size conditions the exploitation of FDI spillovers even after controlling for absorptive capacity. We also detect a great deal of heterogeneity across countries consistent with the technology gap hypothesis.     

When do firms support environmental agreements?

Several firms have recently supported their countries’ participation in international environmental agreements where countries commit to stricter environmental regulation. This paper analyzes the rationale of this conduct by examining equilibrium emission standards with and without environmental treaties. We identify that more stringent environmental regulation produces two effects on firm profits: a negative effect due to larger abatement costs, and a positive effect that arises from the amelioration of duopoly overproduction. We describe under which conditions the positive effect dominates the negative effect, increasing firm profits, and inducing them to support their countries’ participation in environmental treaties.     

Endogenous overhead costs,firm size,and fiscal shocks

Recent empirical observations indicate that firm size responds to cyclical fluctuations in economic activities. By analyzing the effects of endogenous overhead costs in the economy, this paper finds that in response to a fiscal expansion, firm size will increase if the relationship between overhead costs and the number of firms is positive, while firm size will decrease if the relationship is negative.     

Impact of firm heterogeneity on direct and spillover effects of FDI: Micro-evidence from ten transition countries

This paper presents a comparative study of the importance of direct technology transfer and spillovers through FDI on a set of 10 transition countries, using a common methodology and appropriate methods to account for selection and simultaneity correction. This paper considers by far the largest firm level dataset (more than 90,000 firms) used by any study on the spillover effects of FDI. The main novelty of the paper is the explicit control for various sources of firm heterogeneity when accounting for different effects of FDI on firm performance. This work shows that the heterogeneity of firms in terms of absorptive capacity, size, productivity and technology levels affect the results. Controlling for these variables leads to some interesting results, which contrast with the previous empirical work in the field. We find that horizontal spillovers have become increasingly important over the last decade, and they may even become more important than vertical spillovers. Positive horizontal spillovers are equally distributed across size classes of firms, while negative horizontal spillovers seem to be more likely to accrue to smaller firms. Moreover, positive horizontal spillovers seem more likely to be present in medium or high productivity firms with higher absorptive capacities, while negative horizontal spillovers are more likely to affect low to medium productivity firms. These findings suggest that both direct effects from foreign ownership as well as the spillovers from foreign firms substantially depend on the absorptive capacity and productivity level of individual firms. In addition, these results show that foreign presence may also affect smaller firms to a larger extent than larger firms, but this impact may be in either direction.
