Development Aid to Agriculture and Economic Growth

The link between foreign aid and economic growth has been a controversial issue with no strong consensus so far. This paper argues that a possible reason why some studies may conclude that aid is ineffective in promoting economic growth might be that not all aid is given for development purposes (i.e. aid given for strategic considerations, humanitarian reasons or emergency relief). This study classifies foreign aid into four subcategories: agricultural aid, social infrastructure aid, investment aid, and non‐investment aid. Using the generalized method of moments (GMM) estimation technique on a Barro type growth regression with panel data from the aid recipient economies, this paper finds that when aid is directed to the agricultural sector of the developing countries, it is positively and significantly related to growth and can affect economic growth in the short run.     

Analysts’ Momentum Recommendations

We document that the likelihood of analyst recommendations following past stock returns decreased abruptly in 2003, coinciding with the Global Settlement and other regulatory changes designed to restrain analysts’ conflicts of interest. We also document that the likelihood of recommendations following past stock returns is abnormally high for recommendations issued after negative stock returns (but not for those issued after positive stock returns), among inexperienced and inaccurate analysts, among large brokerage houses, and for companies with high share turnover. Moreover, the recommendations that are more likely to follow past stock returns are accompanied by earnings forecast revisions that are larger in magnitude and less accurate ex post. Overall, our findings suggest that analysts with conflicts of interest and limited ability are more likely to base their recommendations on past stock returns. Finally, we document that the recommendations that are more likely to follow past stock returns (especially those that were issued before 2003 and those that are issued after negative stock returns) contribute to existing price momentum by generating incrementally stronger short‐term and long‐term stock returns.     

Traveler satisfaction in rapid rail systems: The case of Istanbul metro

Multifaceted characteristics of urban travel have an impact on the passengers' overall satisfaction with the transport system. In this study, we investigate the interrelationships among traveler satisfaction, travel and traveler characteristics, and service performance in a multimodal network that comprises of a trunk line and its feeder lines. We analyze the factors influencing the choices of access to rail transit stations and the satisfaction of transit travelers with the rapid rail transit systems. We quantitatively study these relationships and demonstrate the complexity of evaluating transit service performance. Since the interrelationships among variables affecting this system are mainly stochastic, we analyze the satisfaction with transit system problem using a Bayesian Belief Network (BBN), which helps capture the causality among variables with inherent uncertainty. Using the case of Istanbul, we employ the BBN as a decision support tool for policy-makers to analyze the rapid rail transit services and determine policies for improving the quality and the level of service to increase the satisfaction with transit system. In the case study, satisfaction with accessibility and access mode variables are found to be more effective variables than total travel time for travel time satisfaction, confirming the significant role of access in multimodal travels.     

What Triggers Inflation in Emerging Market Economies?

This study aims at investigating the factors associated with the start of 24 inflation episodes in 15 emerging market economies (EMEs) between 1980 and 2001. The paper employs pooled probit analysis to estimate the contribution of the key factors to inflation starts. The empirical results suggest that increases in the output gap, agricultural shocks, and expansionary fiscal policy raise the probability of inflation starts in EMEs. The findings also indicate that a more democratic environment and an increase in capital flows relative to GDP reduce the probability of inflation starts. JEL no. E31, E58     

Money demand, the Cagan model, testing rational expectations vs adaptive expectations: The case of Turkey

This paper estimates the Cagan type demand for money function for Turkish economy during the period 1986:1–1995:3 and tests whether Cagan's specification fits the Turkish data using an econometric technique assuming that forecasting errors are stationary. This paper also tests the hypothesis that monetary policy was implemented in aiming to maximize the inflation tax revenue. Finally, the Cagan model is estimated with the additional assumption of rational expectations for Turkey for the considered period.

The manager’s role in enhancing the transfer of training: a Turkish case study

The process of the transfer of training has a great impact on job productivity, effectiveness and satisfaction. Studies focusing specifically on the role of managers in the process have, however, been limited in number. The general aim of this study is to determine the impact of managers’ reinforcement on participants’ job attitude, productivity, effectiveness and satisfaction in the process of the transfer of knowledge, skill and attitude to be acquired through a training programme into the workplace. The study involves a group of sales representatives participating in the Basic Sales Training Program for Sales Representatives and their supervisors in the Coca‐Cola Bottlers of Turkey. Using experimental and control groups, the study is based on Kirkpatrick’s four–stage evaluation model. The findings obtained are discussed and evaluated with respect to the roles of managers in the transfer of training.     

Foreign Aid and the Quest for Poverty Reduction: Is Aid to Agriculture Effective?

Development statistics estimate that three quarters of the poor live in rural areas and most of them depend on agriculture and related activities for their livelihood. Consequently, research focusing on economic growth and poverty reduction has found that sustainable rapid transition out of poverty requires a special emphasis on the agricultural sector. This study contributes to the debate on aid effectiveness by disaggregating total aid into subcategories and specifically investigating the relationship between aid given to the agricultural sector and poverty reduction. If agricultural development is more effective in reducing poverty than some other types of development, then foreign aid directed towards agriculture may be more efficient in increasing the well‐being of the poor than aid directed to some other sectors or uses. Our analysis uses panel data for developing aid recipient countries to empirically test this relationship. We find a significant relationship between agricultural aid and poverty reduction in our estimates.
