Political regimes: a coalition formation approach

What leads to the stability of a particular regime and what causes its demise? With the aid of formal modeling, the paper illustrates the necessary and sufficient conditions for different political regimes to exist. The game involves two factions representing the differing interests of the civil society and the armed forces of a nation. We illustrate the emergence of political regimes that includes both unconstrained and constrained democracies, both military and civilian autocracies and an alliance formed by a segment of the civil society and the military.     

Trade openness and income inequality in China and the SAARC Region

The paper empirically examines the effects of trade liberalisation on income inequality in China and the South Asian Association for Regional Cooperation countries. Panel data analysis is conducted for the period of 1973 to 2012. The results show that liberal trade policies have increased income inequality in these countries. These results are robust to alternative liberalisation measures. The control variables used have differing effects on income distribution. Per capita income has an increasing effect on income inequality, while education, financial development, financial openness, democracy, and government size are shown to reduce income inequality. These outcomes can be expected to have important policy implications for the use of trade liberalisation in these countries.     

L'Hypothése de la Distribution Normale dans le cas d‘Événements Simultanes

L'hypothèse de la distribution normale lors de l'analyse des données, permet entre autres, l'utilisation des tests statistiques classiques, ce que n'autorise pas une distribution asymétrique ou aplatie au centre et allongée awe extrémités. Ce travails'adresseprécisé-ment à la forme de la distribution des résidus quotidiens dans le cas d'évènements simultanés, e'est-d̀-dire ceux affectant un certain nombre d'entreprises au mǐme moment, puisque aucune étude ne s'est préoccuppée, à notre connaissance, de ce phénomène. Nos résultats semblent indiquer que les hypothèses de la distribution normale et de non-aplatissement des résidus quotidiens dans le cas d'événements simultanés sont irréalistes, le sort de l'hypothèse d'asymétrie ne semblepas clair surtout à un intervalle de condiance de 99 pourcent. L'utilité des tests statistiques classiques se trouve, par conséquent, très minimisée. Ces tests auront, en effet, tendance à rejeter l'hypothèse de performance normale mǐme en l'absence de toute performance anormale. Abstract The hypothesis of normal distribution in the analysis of data permits, among other things, the use of classical statistical tests. This is not allowed by a distribution which is asymetric or flat at the center and extended at the extremities. This paper deals specifically with the shape of the distribution of daily remainders in the case of simultaneous events which affect a number of businesses at the same time because, to our knowledge, no study has previously dealt with this phenomenon. Our results seem to indicate that the hypothesis of normal distribution and of the non-flattening of daily remainders in the case of simultaneous events are unrealistic and the outcome of hypothesis of asymetry does not seem clear especially at a 99% confidence interval. As a result, the use of classical statistical tests is minimized. In effect, these tests will generally reject the hypothesis of normal performance even in the absence of any abnormal performance.     

How costly is the Sarbanes Oxley Act? Evidence on the effects of the Act on corporate profitability

The Sarbanes-Oxley Act (SOX) was intended to protect investors by improving the accuracy and reliability of corporate disclosures. However, critics have argued that the costs of SOX far outweigh its intended benefits. Prior studies based on stock-price reactions to SOX-related events document mixed evidence on the expected impact of SOX. In contrast, we provide evidence on the net realized costs of SOX by examining its impact on operating profitability. We find that average cash flows decline by 1.3% of total assets after SOX. These costs are more significant for smaller firms, for more complex firms, and for firms with lower-growth opportunities. Annually, these costs range from $6 million for smaller firms to $39 million for larger firms. Further, we document that net SOX-related costs are not limited to one-time expenses associated with internal-control design and implementation. In aggregate, for the 1428 firms in our sample, these costs amount to about $19 billion per year. Profitability is lower for up to four years post-SOX. To our knowledge, ours are the first estimates of the realized net costs imposed by SOX.     

Liquidity constraints,productivity, employment and output: evidence from non-agricultural activities in Bangladesh

This paper examines the role played by liquidity constraints in determining non-agricultural employment, labour productivity and output among poor, landless households. The hypothesis that the provision of credit to poor non-agricultural households on reasonable terms can greatly enhance labour use, and output, thereby reducing poverty is empirically investigated using survey data from rural landless households in Bangladesh. The study's findings indicate that even small amounts of credit on reasonable terms can substantially enhance labour use and income for poor households and that the impact is greatest for the poorest households.     

Immigrants’ Wage Performance in a Routine Biased Technological Change Era: France 1994–2012

Over the period 1994–2012, immigrants’ wage growth in France outperformed that of natives. We investigate to what extent changes in task‐specific returns to skills contributed to this wage dynamics differential through two channels: changes in the valuation of skills (price effect) and occupational sorting (quantity effect). We find that the wage growth premium of immigrants is mainly explained by the progressive reallocation of immigrants toward tasks whose returns increase over time. Immigrants seem to have taken advantage of labor demand restructuring driven by globalization and technological changes.     

Pillion riders' cloth related injuries and helmet wearing patterns: a study of Lahore,Pakistan

This study aims at investigating the burden and pattern of clothing related pillion riders' injuries and their helmet wearing pattern in Lahore, Pakistan. Data were collected for nine months (July 2013 to March 2014), reporting 13,248 motorcycle related injuries, out of which 8751 (66%) cases were related to the clothing related pillion riders' injuries. Out of these injuries 10.30% were severe injuries which can be prevented or reduced by proper safety measure, e.g. wearing helmet. It was also found that most of the fatalities were not wearing helmet. Injuries due to wearing of loose fitting clothes and absence of helmet are not uncommon in Pakistan and other underdeveloped parts of the world. Such accidents may be reduced by creating awareness and safety sense in the riders, where use of safe dress and helmet should be encouraged in order to avoid such fatal damages.     

Understanding the Relationship between Inflation and Growth: A Wavelet Transformation Approach in the Case of Bangladesh

This paper re‐examines the relationship between inflation and economic growth in developing countries. Both the theoretical and the empirical literature are extremely divided on this issue. We apply a relatively new empirical technique – the continuous wavelet transform – to Bangladesh. Bangladesh is of interest because of its remarkable economic growth and poverty reduction during the last 30 years in combination with, for a developing country, a controlled inflation. The wavelet analysis is a contribution because it displays how the correlation and the lead–lag structure between variables change over timescales, taking into account that growth and inflation can follow several different cycles. Comovements between variables are generally studied in the time domain. Results from studies in the time‐domain study can be sensitive to the frequency of observations. On the other hand, studies in the frequency domain are not easily translated into time domains that can be associated with economic policies. The wavelet methodology finds a balance between time and frequency domains. Our study finds that growth Granger causes inflation at all frequency scales, starting from the short run to the very long run. Inflation, on the other hand, Granger causes growth in the long run but not in the short run. This result has implications for Bangladesh, and as such for similar developing countries, where some policymakers believe that inflation must be kept at very low levels for sustained economic growth.     

Luddites, the industrial revolution, and the demographic transition

Technological change was unskilled-labor-biased during the early industrial revolution, but is skill-biased today. This implies a rich set of non-monotonic macroeconomic dynamics which are not embedded in extant unified growth models. We present historical evidence and develop a model which can endogenously account for these facts, where factor bias reflects profit-maximizing decisions by innovators. In a setup with directed technological change, and fixed as well as variable costs of education, initial endowments dictate that the early industrial revolution be unskilled-labor-biased. Increasing basic knowledge then causes a growth takeoff, an income-led demand for fewer but more educated children, and a transition to skill-biased technological change in the long run.     

The shopping list in goal-directed shopping: scale development and validation

This paper aims to develop and validate a shopping list scale in a goal-directed shopping context based on three complementary study phases (and literature review): shopper interviews (exploratory stage to identify the items and dimensions), a pilot study with 162 respondents for scale purification, and a refined questionnaire administered to 213 respondents (to establish reliability, convergent, discriminant and nomological validity). An exploratory factor analysis shows that the items load onto four factors: memory aid, money controller, shopping controller, and deviation controller. We performed confirmatory factor analysis to test the model and check for reliability and validity of the anticipated scale. The model fit and reliability levels are acceptable, as are the convergent and discriminant validities of the scale. The scale is a second-order factor, thus satisfying nomological validity. The shopping list scale should be of interest to researchers and retail managers in exploring factors and outcomes of goal-directed shopper behaviour.
