On durable goods markets with entry and adverse selection

Abstract. We investigate the nature of trading and sorting induced by the dynamic price mechanism in a competitive durable good market with adverse selection and exogenous entry of traders over time. The model is a dynamic version of Akerlof (1970) . Identical cohorts of durable goods, whose quality is known only to potential sellers, enter the market over time. We show that there exists a cyclical equilibrium where all goods are traded within a finite number of periods after entry. Market failure is reflected in the length of waiting time before trade. The model also provides an explanation of market fluctuations. JEL classification: D82 A propos des marchés de biens durables quand il y a entrée de nouveaux commerçants et sélection adverse. Les auteurs analysent la nature du commerce et du triage engendrés par le mécanisme dynamique des prix dans un marché concurrentiel de biens durables quand il y a sélection adverse et entrée exogène de nouveaux commerçants dans le temps. Ce modèle est une version dynamique du modèle d’ Akerlof (1970) . Des cohortes identiques de biens durables, dont la qualité est connue seulement des vendeurs potentiels, arrivent sur le marché dans le temps. Il semble qu’il y ait plus de commerce actif que ce qui est prévu par un modèle statique. En particulier, on montre qu’il existe un équilibre cyclique où tous les biens sont transigés à l’intérieur d’un nombre fini de périodes après leur arrivage et que, à chaque phase du cycle, l’éventail de qualité des biens transigés s’accroît. Les commerçants qui transigent des produits de plus haute qualité attendent plus longtemps et l’imperfection du marché se traduit par la longueur de temps d’attente avant la transaction. Le modèle fournit aussi une explication des fluctuations du marché.     

On sustained economic growth with wealth effects

In a discounted one-sector convex model of optimal economic growth where utility may depend on both consumption and capital stock, I derive necessary and sufficient conditions for sustained growth (unbounded expansion of capital and consumption). Conditions for bounded growth and extinction are also outlined. Optimal paths may be non-monotone. Sustained growth may occur even though the asymptotic marginal productivity is less than the discount rate and may require the initial capital stock to be above a critical level. The behavior of the marginal rate of substitution between consumption and capital plays a crucial role in the conditions.     

Cost-Reducing Investment, Competition, and Industry Dynamics

We demonstrate the possibility of shake-out of firms and emergence of interfirm heterogeneity along the (socially optimal) dynamic equilibrium path of a competitive industry with free entry and exit, even when there is no uncertainty and all firms are ex ante identical with perfect foresight. Atomistic firms with upward-sloping marginal cost curves undertake investment in firm-specific cost reduction. They earn negative net profits in early periods, compensated later by strictly positive net profits; no entry occurs after the initial time period. Some firms may exit before others even while other firms earn positive net profits.     

Organizational energy: an empirical study in Indian R&D laboratories

Analyzing the way organizations function and the processes that operate within these organizations is an important managerial responsibility. We have adopted a people–oriented approach called organizational energy to develop a simple process for diagnosing the level of satisfaction of scientists working in R&D laboratories. Psychic energy as reflected in different work activities in an organization is manifested in energy generating and energy draining activities that can be reduced to an energy count. The present study assesses the use of mental energy by scientific personnel working in three national laboratories in India with the objective of increasing the energy count for improving organizational effectiveness. We hope that the results can be used as the basis for initiating action to improve the motivation and utilization of scientists in India, to support the overall goal of self–reliance in science and technology.     

On Sustained Growth Under Uncertainty

We analyze a stochastic one‐sector model of economic growth and investigate the conditions under which long‐run growth occurs almost surely. In contrast to the deterministic version of the model, the utility function plays a crucial role in determining the long‐run behavior of output.     

Determinants of employees’ attitudes toward union membership in India

Drawing on data from a survey of 252 unionized full-time employees from large Indian organizations, this study examined whether individual level job related variables and individual cultural value dimensions of individualism–collectivism (I–C) were predictive of employees’ attitudes toward union membership. Using regression analysis, the author found that over and above the effects of demographic and job-related variables, work situation dissatisfaction and perceived work stress were able to predict union attitudes significantly and positively for the sample. The relationship of union attitude was highly significant and negative with a consultative managerial style. Collectivism was able to predict the union attitudes positively, whereas individualism was negatively related to the union attitudes. The interaction between employees’ perceived work stress and work situation dissatisfaction are found to have a positive influence on their union attitudes. The results and implications of findings are discussed in the paper with reference to the literature on role of cultural dimensions (I–C) and job related factors in relation to organizational outcomes like union membership.     

Groves mechanisms and communication externalities

We put forward a model of private goods with externalities. Agents derive benefit from communicating with each other. In order to communicate they need to operate on a common platform. Adopting new platforms is costly. We first provide an algorithm that determines the efficient outcome. Then we prove that no individually rational and feasible Groves mechanism exists. We provide sufficient conditions that determine when an individually rational Groves mechanism runs a deficit and we characterize the individually rational Groves mechanism that minimizes such deficit whenever it occurs. Moreover, for 2-agent economies, we single out the only feasible and symmetrical Groves mechanism that is not Pareto dominated by another strategy-proof, feasible and symmetrical mechanism.     

Growth and inequality: Dependence on the time path of productivity increases (and other structural changes)

This paper examines the significance of the time path of a given productivity increase on growth and inequality. Whereas the time path impacts only the transitional paths of aggregate quantities, it has both transitional and permanent consequences for wealth and income distribution. Hence, the growth-inequality tradeoff generated by a given discrete increase in productivity contrasts sharply with that obtained when the same productivity increase occurs gradually. The latter can generate a Kuznets-type relationship between inequality and per-capita income. Our results suggest that economies with similar aggregate structural characteristics may have different outcomes for income and wealth inequality, depending on the nature of the productivity growth path.     

Auditing regulations and bank shareholders’ wealth: An international analysis

This paper examines the ability of auditing regulation to protect bank shareholders’ wealth during the time of normal growth and during the 2007–2009 global financial crises. The study uses the bank regulation database available at the World Bank website. We select a sample of 2467 banks from 107 countries for the years 1999–2009. We perform multivariate regression analyses and find that while auditing regulations enhance bank equity prices in normal growth periods, there is no evidence that auditing regulations are associated with bank share prices during the period of financial crisis. We observe similar results for both developed and emerging countries and for the common and code law countries. Our results suggest an immediate need to strengthen audit regulations so that investor confidence is more likely to persist during periods of financial downturn.     

Constructing Transnational Solidarity: The Role of Campaign Governance

Our inductive study of two transnational labour solidarity efforts focuses on the role of campaign governance. Specifically, we study contrasting campaign strategies, tactics and coalition structures in campaigns by two global union federations, UNI Global Union and the IUF, contextualized in terms of how these campaigns unfolded in India. Our contribution consists of two arguments. The first is that a degree of internal consistency amongst different campaign elements is important for success, and the second is that a mode of articulation that allows for local concerns in affiliate countries to find voice in global campaigns is more likely to result in concrete gains at the local level.
