The lexicographic composition of abstract games

The lexicographic composition of reflexive and complete binary relations (which are often called abstract games) is studied. The necessary and sufficient conditions are obtained for a lexicographic composition of quasi transitive relations to be quasi transitive.The case of acyclicity of lexicographic composition of two relations is also investigated.

Relationship Between Competitive Intensity,Internal Resources,and Firm Performance: Evidence from Indian ITES Industry

The purpose of this article is to investigate how competitive intensity impacts the relationship between crucial firm resources (human capital, organizational capital, management capability) and firm performance. Using a sample of 105 service providers from the Indian information technology–enabled services (ITES) industry, I find that competitive intensity positively moderates the relationship between firm resources and firm performance such that the relationships become stronger when competitive intensity is high than when it is low. Results imply that top managers' evaluation of the performance implications of internal firm resources are significantly shaped by the perceptions of intensity of competition encountered by their firms. © 2013 Wiley Periodicals, Inc.     

Reparations for African‐Americans as a Transfer Problem: A Cautionary Tale

We examine how different methods of reparations payments to African‐Americans affect both the black and nonblack populations of the United States using the framework of the transfer‐problem from international trade theory as a theoretical foundation. We find that reparations payments that provide incentives for blacks to use the payment toward purchases of goods and services produced by nonblacks might expand the income gap. Also a reparations payment in the absence of productive capacity owned by blacks is found to have no final positive impact on black income. These results indicate that a reparations payment strategy must be carefully and cautiously conceived in order to achieve the desired effects.     

Co-evolution of institutional and organizational factors in explaining offshore outsourcing

Offshore outsourcing of business functions is widely practiced by firms in advanced economies. Although scholars have argued for various theoretical perspectives in explaining its nature and implications, a coherent explanation of how crucial factors that aid this growing phenomenon coevolve has not been offered. Further, a potential gap in the extant literature concerns inadequate simultaneous attention to clients and providers – the key actors in offshore outsourcing. With an aim to fulfill these research gaps, we provide in this paper an integrated framework wherein we delineate various institutional and organizational factors that coevolve to enable engagement of clients and providers in offshore outsourcing. Our conceptualization draws from information obtained by interviewing 46 executives of 31 firms of the Indian business process outsourcing industry.     

Foreign Direct Investment, Local Content Requirement, and Profit Taxation

We develop a partial equilibrium model of foreign direct investment (FDI) in which identical foreign firms locate themselves in a host country to compete in an oligopolistic market for a non-tradeable commodity. The host country, assumed to be small in the market for FDI, makes use of two instruments, viz., a profit tax and a local content requirement, to compete for FDI in the international market. We assume the existence of unemployment in the host country. The structure of optimal instruments and their relationship to the number, and the relative efficiency levels, of the domestic firms, are established     

Evolution of forecast disagreement in a Bayesian learning model

We estimate a Bayesian learning model with heterogeneity aimed at explaining expert forecast disagreement and its evolution over horizons. Disagreement is postulated to have three components due to differences in: (i) the initial prior beliefs, (ii) the weights attached on priors, and (iii) interpreting public information. The fixed-target, multi-horizon, cross-country feature of the panel data allows us to estimate the relative importance of each component precisely. The first component explains nearly all to 30% of forecast disagreement as the horizon decreases from 24 months to 1 month. This finding firmly establishes the role of initial prior beliefs in generating expectation stickiness. We find the second component to have barely any effect on the evolution of forecast disagreement among experts. The importance of the third component increases from almost nothing to 70% as the horizon gets shorter via its interaction with the quality of the incoming news. We propose a new test of forecast efficiency in the context of Bayesian information processing and find significant heterogeneity in the nature of inefficiency across horizons and countries.     

Segmented asset markets and optimal exchange rate regimes

This paper revisits the issue of the optimal exchange rate regime in a flexible price environment. The key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented). Under this friction alternative exchange rate regimes have different implications for real allocations in the economy. In the context of this environment we show that flexible exchange rates are optimal under monetary shocks and fixed exchange rates are optimal under real shocks.     

Oil price shocks on Indian economy: evidence from Toda Yamamoto and Markov regime-switching VAR

The study investigates the dynamic impact of linear and non-linear specifications of oil price shocks on macroeconomic fundamentals for an oil-importing emerging economy – India – during the period March 1991 to January 2009. The paper deploys extended vector autoregressive (VAR) model of possibly integrated processes proposed by Toda and Yamamoto, which has its advantage of application irrespective of the variables being stationary or cointegrated. The study further estimates two-state Markov regime-switch VAR model to examine regime shift behaviour of the underlying variables and its relationship. The study finds that inflation and foreign exchange reserve are greatly impacted by oil price shocks. The study also confirms that the movement in oil price is exogenous with respect to the movement of India’s macroeconomic variables and the impact of oil price shocks are asymmetric in nature with negative price shocks having more pronounced effect than positive shocks.     

Disinflation programs under policy uncertainty

This paper uses a model with endogenous labor supply to study exchange rate-based inflation stabilization programs under uncertainty regarding the duration of the program. The paper finds that the output and consumption dynamics induced by these programs are extremely sensitive to whether the programs are perceived to have a chance of continuing permanently or whether they are expected to end in finite time. It is shown that the business cycle dynamics for output that are typically associated with these programs arise only when the policy is expected to collapse in finite time. Furthermore, for the purposes of rationalizing the stylized facts, the uncertain duration channel appears to induce a fundamental tension between the consumption dynamics and the current account dynamics. These results raise doubts regarding the explanatory power of the uncertain duration channel in particular and the credibility channel in general.     

How quickly do forecasters incorporate news? Evidence from cross‐country surveys

Using forecasts from Consensus Economics Inc., we provide evidence on the efficiency of real GDP growth forecasts by testing whether forecast revisions are uncorrelated. As the forecast data used are multi‐dimensional—18 countries, 24 monthly forecasts for the current and the following year and 16 target years—the panel estimation takes into account the complex structure of the variance–covariance matrix due to propagation of shocks across countries and economic linkages among them. Efficiency is rejected for all 18 countries: forecast revisions show a high degree of serial correlation. We then develop a framework for characterizing the nature of the inefficiency in forecasts. For a smaller set of countries, the G‐7, we estimate a VAR model on forecast revisions. The degree of inefficiency, as manifested in the serial correlation of forecast revisions, tends to be smaller in forecasts of the USA than in forecasts for European countries. Our framework also shows that one of the sources of the inefficiency in a country's forecasts is resistance to utilizing foreign news. Thus the quality of forecasts for many of these countries can be significantly improved if forecasters pay more attention to news originating from outside their respective countries. This is particularly the case for Canadian and French forecasts, which would gain by paying greater attention than they do to news from the USA and Germany, respectively.
