Earnings management and abnormal returns: Evidence from the 1970–1972 Price Control Regulations

We examine the association between abnormal returns and earnings management in the context of price control regulations to test the construct validity of the earnings management model. Abnormal returns are used as a market–based measure, and discretionary accruals are employed to measure earnings management. Our results support the hypotheses that (1) price control regulations affect firms' security prices negatively, (2) firms make income–decreasing discretionary accruals to increase the likelihood of price increase approval, and (3) firms that are affected most negatively by the regulations manage earnings more aggressively. We conclude that the earnings management model we use in this study is capable of predicting opportunistic discretionary accruals.     

The impact of foreign direct investment and trade on economic growth Taking China, Korea, Malaysia, Philippines ＆ Thailand for example

In this study the authors make efforts to survey the impact of foreign direct investment and trade on the economic growth of five East Asian countries, China, Korea, Malaysia, Philippines and Thailand. Using an augmented production function （APF） growth model, the authors apply panel data Method and data span is from1980 to 2006. The required data are extracted from World Development Indicator 2008. The result shows that a co-integration relationship between growth and its determinants in the APF model is supported. Firstly, the study shows that with the increasing the inflow of foreign direct investment, positive impact on growth in Thailand, Korea and China is proved. However, this impact is negative in Philippine and Malaysia. Also the impact of trade on economic growth has the same result with FDI impact in sign. Further, the impact of labor force on growth is not significant in these countries and the effect of gross fixed capital on growth is positive and has a very high impact on selected countries.     

Dynamic routing of time-sensitive air cargo using real-time information

The route planning of time-sensitive air-cargo is becoming more important with the growing air-network congestion and delays. We consider a freight forwarder’s routing of a time-sensitive air-cargo in the presence of real-time and historical information regarding flight availability, departure delays and travel times. A departure delay estimation model is developed to account for real-time information inaccuracy. A novel Markov decision model is formulated and solved with online backward induction. Through synthetic experiments and case studies, we demonstrate that dynamic routing with real-time information can improve delivery reliability and reduce expected cost.     

Corporate philanthropy: Insights from the 2008 Wenchuan Earthquake in China

We explore the equity market impact of board announcements of corporate donations made in response to the May 12th 2008 Wenchuan earthquake in China. Our event study uses a sample of board announcements of corporate donations from Chinese A-share listed companies. We find that donor companies providing products and/or services directly to end-consumers tend to enjoy higher abnormal stock returns, thereby documenting a link between corporate social responsibility and corporate financial performance at least for some corporate citizens. In light of the empirical results, the study suggests that corporate philanthropic involvement should be treated as a differentiated type of marketing tool to obtain social reputation and publicity, as well as a relationship cultivation mechanism with local government authorities.     

Payoff Assessments without Probabilities: A Simple Dynamic Model of Choice

We develop a model which reflects the tendency of people to simplify the decision problems they face. The decision maker chooses among alternate strategies only on the basis of the payoff she assesses she would obtain from them, and these assessments do not explicitly take into account her subjective judgements regarding the likelihood of alternate states of the world. At each stage, the decision maker chooses the strategy that she assesses to give the highest payoff. She updates her assessments adaptively. We show that such behavior leads to maxmin choices. We also consider the decision maker who experiences shocks. Journal of Economic Literature Classification Numbers: C7, D8.     

Efficiency of Microfinance Institutions: A Data Envelopment Analysis

This study examines the cost efficiency of 39 microfinance institutions across Africa, Asia and the Latin America using non-parametric data envelopment analysis. Our findings show non-governmental microfinance institutions particularly; under production approach, are the most efficient and this result is consistent with their fulfillment of dual objectives: alleviating poverty and simultaneously achieving financial sustainability. However, bank-microfinance institutions also outperform in the measure of efficiency under intermediation approach. This result reflects that banks are the financial intermediaries and have access to local capital market. It may be possible that bank-microfinance institutions may outperform the non-governmental microfinance institutions in the long run.     

Eco-labelling and environmental policy efforts in developing countries

Eco-labelling has become an increasingly popular instrument in recent years. Among the new developments which have been called for are that they should also be used as a means of encouraging developing countries to apply stricter environment policies. The following article investigates whether applying environmental seals of approval to the export products of developing countries is an efficient instrument for the purpose.     

Adjustment constraints in developing countries

The debt crisis of the eighties has compelled many developing countries to catch up on a painful adjustment backlog. In addition to traditional stabilization measures sponsored by the IMF, many countries are now acquainted with the structural adjustment programmes of the World Bank. Some have implemented these programmes successfully, others have terminated them after a short period or only partially completed them. What are the reasons for this?     

Inflation-inflation uncertainty nexus in Iran——Using TARCH model

This paper examines the relationship between inflation and inflation uncertainty in Iran economy using monthly data of Iran over the period 1990-2009. TARCH model is used to peruse the stochastic variation and asymmetries in the economic instruments. The result indicates that there is a positive relationship between inflation and inflation uncertainty. Also, the authors investigate from the Granger causality test that inflation is Granger causality of inflation uncertainty.     

Nonlinear Correlograms and Partial Autocorrelograms*

This paper proposes neural network‐based measures of predictability in conditional mean, and then uses them to construct nonlinear analogues to autocorrelograms and partial autocorrelograms. In contrast to other measures of nonlinear dependence that rely on nonparametric estimation of densities or multivariate integration, our autocorrelograms are simple to calculate and appear to work well in relatively small samples.
