Reexamining momentum profits: Underreaction or overreaction to firm-specific information?

We design a new measure and find that the predictability of past returns on future returns increases as stocks respond with delay to firm-specific information. Our results suggest that momentum is caused by both investors’ underreaction and overreaction to information. However, underreaction to information seems to be the primary cause, particularly during the more recent period. Our findings are robust for recent explanations of momentum profits and alternative methods for computing our measure. We also find that stocks respond with delay to firm-specific information, partly due to certain firm characteristics, and partly because they escape investor attention due to their low visibility. Our paper extends and refines Jegadeesh and Titman’s (J Financ 56(2):699–720, 2001) finding that momentum profits are consistent with behavioral models’ predictions regarding investors’ overreaction.     

Export performance of emerging market firms

I investigate the export performance of firms from emerging economies based on resource based view (RBV) of a firm. Based on review of extant literature, I identify firm size, research and development expenditure, advertising expenditure and business group affiliation to be important antecedents of level of exporting activities of a firm. I utilize a two-stage least square estimation (G2SLS) on a sample of 47,140 firm-year observations over a period of sixteen years from 1990–2005. The findings suggest that export sales and domestic sales are interdependent and affect each other. R&D expenditure and business group affiliation positively affect export sales, however advertising expenditure negatively affects export sales.     

Contests where there is variation in the marginal productivity of effort

Summary. We provide a characterization of participants' behavior in a contest or tournament where the marginal productivity of effort varies across contestants and individual productivity is private information. We then consider the optimal design of such a contest. We first analyze contestant behavior for the usual type of contest, where the highest output wins. Abilities need not be independently distributed. We demonstrate that there is a unique symmetric equilibrium output function, that output is increasing in ability, and that marginal effort is increasing in ability, while effort decreases when the cost of effort increases. Next we consider the case where the highest output need not win, with independently distributed abilities. We analyze the contest designer's decisions in choosing contest rules optimal from her perspective. We show that the output produced, probability of winning, and contest designer's expected revenue are generally increasing in contestants' ability. We examine the relationship between the marginal cost of producing output and marginal utility per dollar of the net award for winning. Received: July 30, 1998; revised version: August 7, 2000     

Subsidiary staffing,cultural friction,and subsidiary performance: Evidence from Korean subsidiaries in 63 countries

Drawing from the notion of cultural friction and based on the agency theory rationalization of multinational enterprise (MNE) headquarter–subsidiary relationship, we examine the impact of cultural friction in foreign subsidiaries on subsidiary performance. We argue that cultural friction, arising due to a high presence of parent country nationals (PCNs) in culturally distant locations, has a detrimental effect on subsidiary performance. This effect is the strongest when the cultural friction is at the top management team (TMT) level and the weakest when friction is at the regular employee level. However, this relationship is contingent on factors that work as drags or lubricants for cultural friction between PCNs and host country nationals (HCNs). We identify governance mode and language differences between home and host countries as drag parameters and host country experience and subsidiary interdependence as lubricants that condition the effect of cultural friction on subsidiary performance. Empirical findings based on a longitudinal sample of 7,495 foreign subsidiary observations of 467 Korean MNEs in 63 countries during 1990–2014 provide robust support for our theoretical predictions.     

The Impact of Natural Hazards on Housing Values: The Loma Prieta Earthquake

A large, detailed data set is used to examine the effect of the Loma Prieta (World Series) earthquake on housing prices in the San Francisco Bay area. This relationship is examined while controlling for potential confounding variables, such as location-specific risk and the timing of the earthquake. The results indicate that the Loma Prieta earthquake caused an area wide reduction in property values. In addition, it seems that individuals considered other measures of earthquake risk in their housing purchases, yielding a measurable price gradient. These results are relatively robust, remaining stable across estimated functional forms and independent variable sets.     

(Farmer) Producer Companies in India as new generation cooperatives: Case studies of performance and impact from West Bengal,India

One of the innovative alternatives to the traditional cooperative structure has been the new generation cooperatives or cooperative companies, known as producer companies (PCs) in India since the early 2000s. This paper examines the impact of PCs on the member farmer livelihoods, which is not well studied, with the help of member and non-member farmer interview survey in the Indian state of West Bengal. It is found that though the PCs were inclusive of small farmers in their membership, the PC interface with members for farm inputs was not very strong and the output linkage was poor, reaching only a small proportion of member farmers. The Sufal Bangla public supermarket franchise by some PCs was found to make a large difference to the PC performance and its impact on member farmers. The small size of membership in most case study PCs hindered the equity size, leading to working capital and market interface constraints. Therefore, it is important to encourage members to contribute more equity and to reward their output linkage.     

Does diversity matter? A fresh inquiry into the energy,economy and environment nexus

ABSTRACT

The article extends the literature on the nexus among economy, environment and energy by incorporating an index of electricity generation diversity in production and emission functions. The index is mathematically equivalent to Herfindahl–Hirschman index. The index captures substantial information regarding the ongoing energy transition at the global level. The results obtained through pooled mean group estimation, on a dataset of fairly diversified group of countries, indicate that if diversity index increases by a percentage point, per capita income increases by 2.4% and per capita emissions are reduced by 0.71%. This is against the conventional wisdom in favour of specialization. The study has found some interesting long-run causal pathways. Firstly, the causality runs from diversification to income. Secondly, there is a causality running from electricity consumption to specialization. Thirdly, bi-directional causality runs between emissions and specialization. The results have interesting policy implications. The study supports the growth hypothesis that the electricity consumption drives the economy. As this inevitably increases emissions, a better pathway is through diversification. The fossil fuel intensive pathway may have been the preferred choice in the past for countries with low electricity consumption; the diversified portfolio appears to be prudent in the future.
