Emerging market hedge funds: Do they perform like regular hedge funds?

In this study, we investigate whether the performance of emerging market hedge funds (EMHFs) follow a pattern similar to that reported for advanced market hedge funds. In contrast to the pre-2007 period, our results for the post-2006 period show that EMHFs exhibit performance patterns similar to those reported for hedge funds that focus on the developed markets. Unlike in the pre-2007 period, EMHFs in general do not exhibit significant exposure to specific asset classes in the post-2006 period. On a risk-adjusted basis, we find that EMHFs do not consistently outperform the benchmarks. The reported performance patterns may provide useful insights to both academics and portfolio managers.     

Profit Maximization and the Market Selection Hypothesis

We examine the proposition that competitive firms must behave as if they were maximizing profits; otherwise they would go bankrupt, or even fail to be financed in a competitive capital market. We investigate a model in which an entrepreneur raises funds for a risky enterprise on a competitive capital market, by offering a "dividend policy" based on the realized (stochastic) flow of earnings. We show that an entrepreneur who maximizes the expected sum of discounted dividends is sure to fail in finite time. On the other hand, many other behaviours yield positive expected profits and are able to attract investment funds, and yet result in a positive probability of surviving forever. As a consequence, if new firms have sufficiently diverse behaviours, then even if there is a constant stream of new entrants, after a long time practically all of the surviving firms will not have been maximizing profits.     

Asset Valuation and Performance Measurement in a Dynamic Agency Setting

This paper examines the choice of asset valuation rules from a managerial control perspective. A manager creates value for a firm through his effort choices. To support its operating activities, the firm also engages in financing activities such as credit sales to its customers. Since such financing activities merely change the pattern of cash flows across periods, an optimal compensation scheme must shield the manager from the risk associated with the financing activities. We show that residual income combined with fair value accounting for receivables eliminates this risk and provides an optimal performance measure. In contrast, compensation schemes based only on realized cash flows can be optimal only under exceptional circumstances. We also consider a setting in which there is sufficiently disaggregated information about periodic cash flows so as to eliminate not only the risk associated with financing activities but also the risk associated with customer defaults. The principal then wants to depart from fair value accounting.     

Correlated equilibria, incomplete information and coalitional deviations

This paper proposes new concepts of strong and coalition-proof correlated equilibria where agents form coalitions at the interim stage and share information about their recommendations in a credible way. When players deviate at the interim stage, coalition-proof correlated equilibria may fail to exist for two-player games. However, coalition-proof correlated equilibria always exist in dominance-solvable games and in games with positive externalities and binary actions.     

Child labor and household wealth: Theory and empirical evidence of an inverted-U

Some studies on child labor have shown that, at the level of the household, greater land wealth leads to higher child labor, thereby casting doubt on the hypothesis that child labor is caused by poverty. This paper argues that the missing ingredient may be an explicit modeling of the labor market. We develop a simple model which suggests the possibility of an inverted-U relationship between land holdings and child labor. Using a unique data set that has child labor hours it is found that, controlling for child, household and village characteristics, the turning point beyond which more land leads to a decline in child labor occurs around 4 ac of land per household.     

Accrual Accounting for Performance Evaluation

This paper examines alternative accrual accounting rules from an incentive and control perspective. For a range of common production, financing and investment decisions we consider alternative asset valuation rules. The criterion for distinguishing among these rules is that the corresponding performance measure should provide managers with robust incentives to make present value maximizing decisions. Such goal congruence is shown to require intertemporal matching of revenues and expenses, though the specific form of matching needed for control purposes generally differs from GAAP. The practitioner oriented literature on economic profit plans (EPP) has made various, and at times conflicting, recommendations regarding adjustments to the accounting rules used for external financial reporting. Our goal congruence approach provides a framework for comparing and evaluating these recommendations.     

Risk management strategies using seasonal climate forecasting in irrigated cotton production: a tale of stochastic dominance

Decision-making in agriculture is carried out in an uncertain environment with farmers often seeking information to reduce risk. As a result of the extreme variability of rainfall and stream-flows in north-eastern Australia, water supplies for irrigated agriculture are a limiting factor and a source of risk. The present study examined the use of seasonal climate forecasting (SCF) when calculating planting areas for irrigated cotton in the northern Murray Darling Basin. Results show that minimising risk by adjusting plant areas in response to SCF can lead to significant gains in gross margin returns. However, how farmers respond to SCF is dependent on several other factors including irrigators' attitude towards risk.     

Controls as a Sharable Knowledge Commodity: An Architecture for Open Exchange

The world seems to be getting more dangerous: terrorists; fraudulent corporations; money laundering; hurricanes; pandemics. Governments and organizations respond with a flurry of new controls. In some cases these are centrally mandated (e.g. Sarbanes Oxley). In others, organizations struggle to find their own control solutions. Seldom, however, do organizations work together as a community of common interests to share solutions to their control threats. In this paper we consider how an open exchange of control solutions might be supported electronically. We assume a community of similar organizations that wish to exchange detailed knowledge about organizational control techniques. These might be non-competing institutions, such as libraries, customs agencies, and even universities; or, they may in fact be competing organizations, wishing to exchange control solutions in dimensions where they do not compete – e.g. the airlines exchanging best practice about safety and security. The main point is to propose an information technology architecture that permits a view of organizational controls as shareable, exchangeable knowledge commodities.
