Industry dynamics: Foundations for models with an infinite number of firms

This paper explores the connection between three important threads of economic research offering different approaches to studying the dynamics of an industry with heterogeneous firms. Finite models of the form pioneered by Ericson and Pakes (1995) capture the dynamics of a finite number of heterogeneous firms as they compete in an industry, and are typically analyzed using the concept of Markov perfect equilibrium (MPE). Infinite models of the form pioneered by Hopenhayn (1992), on the other hand, consider an infinite number of infinitesimal firms, and are typically analyzed using the concept of stationary equilibrium (SE). A third approach uses oblivious equilibrium (OE), which maintains the simplifying benefits of an infinite model but within the more realistic setting of a finite model. The paper relates these three approaches. The main result of the paper provides conditions under which SE of infinite models approximate MPE of finite models arbitrarily well in asymptotically large markets. Our conditions require that the distribution of firm states in SE obeys a certain “light-tail” condition. In a second set of results, we show that the set of OE of a finite model approaches the set of SE of the infinite model in large markets under a similar light-tail condition.     

Labor market institutions and industrial performance: an evolutionary study

This study investigates the impact of labor market institutions on industrial performance from a Schumpeterian perspective. We suggest that labor market institutions play a very important role in the process of creative destruction, because they may create an environment that encourages and enforces innovation, and help to reallocate resources, most importantly labor, through swift elimination of weak performers. We specifically look at the effects of the quantity of labor market regulations and inter-industry wage differentials on labor productivity for a panel of 44 countries for the period 1965–1999. Our findings suggest that those countries that introduce more regulations on conditions of employment and wages achieve higher levels of productivity. Moreover, wage compression raises productivity by reallocating resources to productive activities.     

Gold dinar for the Islamic countries?

The Malaysian state of Kelantan has made a historical launch of Gold Dinar and Silver Dirham on 12th August 2010. For the first time in almost 100 years since the fall of the Ottoman Caliphate, a Muslim government introduces Shariah currency. In the eyes of many Muslim scholars, the present interest-based fiat monetary system is flawed as it is incompatible with the objectives of the Islamic law or the Shariah. There have been calls for the resurgence of Islamic Gold Dinar (together with the silver dirham) as it is deemed to be the most appropriate medium of exchange to be used in the Islamic economies. Using data from 1970 to 2007, this paper assesses the empirical desirability of the Organization of Islamic Conferences (OIC) countries to an alternative monetary system (Islamic Gold Dinar) that can potentially enhance the exchange rate stability and credibility. The Structural Vector Autoregression (VAR) method is employed to assess the nature of macroeconomic disturbances among the OIC countries. Specifically, the symmetry in macroeconomic disturbances of the OIC economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). In addition, this paper also investigates the output and price responses of OIC countries of the underlying structural shocks used to shed light on the suitability of these countries to form a monetary union. The preliminary findings of this study suggest the lack of broad linkages within the entire OIC, although there exists scope among some smaller clusters for potential monetary integration based on the symmetry of their business cycles.     

Are impatient farmers more risk-averse? Evidence from a lab-in-the-field experiment in rural Uganda

Based on data from a field-experiment in rural Uganda, we show that impatient farmers are more risk-averse than patient farmers. We relied on a simplified version of the Convex Time Budget (CTB) method to elicit farmers’ time preferences and on an independent method for eliciting their risk-preferences. We report two important findings. First, we show that our simplified CTB method applied to farmers from Uganda replicates the key findings of Andreoni and Sprenger’s lab experiments that involved student subjects. Second, we establish the existence of a negative correlation between risk tolerance and impatience, based on two independent measures.     

The option of joint purchase in vertically differentiated markets

Summary. Within the framework proposed by Mussa and Rosen (1978) for modelling quality differentiation, consumers are assumed to make mutually exclusive purchases. A unique pure strategy equilibrium exists in this case. In this note, we allow consumers to buy simultaneously different variants of the differentiated good. We call this the “joint purchase option”. The paper proposes a detailed analysis of price competition when this option is opened: first, we show that either uniqueness, or multiplicity, or absence of price equilibrium arise, depending on the utility derived from joint purchase relative to exclusive purchase. Second, we characterize these equilibria, whenever they exist.

Professionals inside the board room: accounting expertise of directors and dividend policy

Directors’ personal attributes have significant impacts on governance effectiveness. We study whether directors’ accounting expertise affects corporate financial policy and investigate dividend in specific. We construct a dataset of audit committee directors’ accounting expertise for Standard & Poor 500 firms from 2005 to 2012. We first verify directors’ monitoring roles by showing that firms with accounting expert sitting on their audit committees demonstrate stronger accounting conservatism. In our main tests, we find that these firms maintain lower dividend payment level, which are less sensitive to earnings volatility. This suggests directors’ advisory roles in financial policy. We further show that our accounting expertise cannot be subsumed by management ability. In additional test, we further examine the baseline results conditional on analyst forecast error. Our findings highlight the importance of directors’ professional expertise in fulfilling their governance roles.     

The role of cognitive ability and personality traits for men and women in gift exchange outcomes

We examine the role of cognitive ability and personality traits in a gift exchange experiment. Controlling for cognitive ability and personality characteristics, men offer higher wages than women, and men and women with greater cognitive ability and greater agreeableness on the Big Five personality scale offer higher wages as well. Men provide greater effort than women do, and respond to higher wage rates with greater increases in effort. For both genders, one standard deviation increases in agreeableness and in wages generate similar increases in effort. Serious biases arise from omitting cognitive ability and pooling men and women.     

The roles of stakeholder support and procedure-oriented management on asset recovery

As the management of returned products is fast becoming a business trend caused by pressure for compliance, asset recovery is increasingly viewed as a fertile area for firms to reduce cost and improve quality. Environmental management is a viable approach for Chinese manufacturers to respond to the escalating international quest for conserving the environment, to tackle the problem of rising raw material costs, and to improve product quality by analyzing returned products. To reach the goals of cost reduction and product quality improvement, manufacturers need to understand how asset recovery can be leveraged through procedure-based practices and stakeholder support to enhance performance. Product type, characterized by different levels of demand uncertainty and time-to-market, may affect the outcomes of asset recovery adoption and should also be taken into account. Drawing on the environmental management and business logistics literature, we provide empirical insights on asset recovery adoption using survey data collected from export-oriented Chinese manufacturers. We find that asset recovery and stakeholder support are complementary in strengthening manufacturers' financial performance regardless of product type. In addition, the performance impact of asset recovery can be substantial when manufacturers' environmental management practices are less procedural, allowing flexibility in the logistics management of product flows.     

The impact of environmental management systems on financial performance in fashion and textiles industries

With rising environmental concerns from consumers and stakeholder groups, environmental management has become an important responsibility for today's fashion and textiles manufacturers. The production of fashion and textiles related products often requires high levels of energy and water consumption, and emits large quantities of pollutants to the environment. Therefore, the adoption of environmental management systems (EMSs) is important and could have a significant impact on these firms' operational performance. This study presents empirical evidence on the performance impact of EMS adoption in the fashion and textiles related industries (FTIs). Although EMSs have emerged as a passport to business in the FTIs, their actual impacts on firms' financial performance have not been explored. We reveal that the adoption of ISO 14000, the most popular EMS, improves manufacturers' profitability in the FTIs over a three-year period as measured by return-on-assets (ROA). Based on our sample, we find that profitability improvement started during the implementation stage and continued at least one year after the firm obtained ISO 14000 certification. We also find that profitability improvement is mainly due to improvement in cost efficiency, measured by return-on-sales (ROS). Specifically, certified firms improved up to 2.9% in ROA and 3.3% in ROS over the three-year period since they implemented ISO 14000. We conclude that there is a positive impact of EMS adoption on firms' financial performance in the FTIs.     

Green marketing and its impact on supply chain management in industrial markets

Green marketing and green supply chain have been drawing the attention of both academics and practitioners in the recent decade. However, no holistic framework has been developed on how to build green industrial brands and industrial corporate brands. Whether or not sustainable/green supply chains can be integrated with green industrial marketing in building greener organizations and industrial brands is still unclear. In addition, little is known on the factors on green new industrial product development or how green new industrial products are adopted by organizations. Furthermore, we know little of whether and how green supply chain enables green new industrial product development. This special issue aims at reflecting the most recent advances on green industrial marketing, green/sustainable supply chains and their interplay in green industrial branding, and to explore future research directions. The guest editors hope that the solicited papers can provide insights on the impacts of sustainable or green supply chains on marketing theory in industrial and business-to-business markets.
