A panel study on the relationship between corruption and government size

Using panel data from 1996 to 2005, this paper shows that the effect of government size on corruption is positive at a low level of democracy, but it is negative at a high level. This finding could fill the gaps in previous studies whose findings on the relationship between corruption and government size are controversial.Corruption; Government size; Democracy; Panel data

Endogenous Voter Turnout and Income Redistribution

In this paper, a simple model is proposed to endogenize voting behavior that incorporates a sense of duty to vote. We assume that a sense of duty to vote is an increasing function of a person's human capital and the public faith in politics, and those with a higher sense of duty often vote. Then, we examine the relationship between income redistribution policy and human capital accumulation. From our assumption, the voter turnout is expected to gradually increase as human capital accumulates. However, we show that, in some cases, the positive relationship between voter turnout and human capital accumulation is not necessarily hold. In addition, the effect of growing inequality on the redistribution policy is investigated.Voter turnout, Human capital, Income distribution, Redistribution

A study on the relationship between corruption and government size: the role of democracy

Previous studies on the effect of government size on corruption have produced mixed results. For the purpose of explaining these ambiguous results, our study investigates the effect of government size on corruption by taking into account the role of democracy level in each country. Using annual data from 82 countries from 1995 to 2008, the estimation results indicate that an increase in government size can lead to a decrease in corruption if democracy level is sufficiently high and, in contrast, can lead to an increase in corruption if it is too low. As a robustness check, estimations using a different index of corruption and a different proxy for government size are also conducted. The results show that our main results are robust. Furthermore, to deal with endogeneity problems, we conduct an instrumental variable estimation, the results of which support our main results. These findings provide some important implications for policymakers seeking to conduct government intervention without aggravating corruption.Corruption; Government Size; Democracy; Instrumental Variable Estimation

How Does Democratization Affect the Composition of Government Expenditure?

This study examines the effects of democratization on the size and composition of government expenditure using the data of 125 countries between 1972 and 2010 at most. Specifically, we focus not only on the total expenditure but also on their composition and employ dichotomous indices of political regimes rather than score indices. Moreover, we construct instruments for democratization based on the democratization wave and conduct an instrumental variables estimation to address endogeneity problems. Our results show that while democratization does not have a significant impact on total expenditure, it increases expenditure on health and education and decreases expenditure on defense. Furthermore, considering the time-varying effect of democratization, defense expenditure starts decreasing immediately after a regime change and health expenditure increases in the medium and long run, while they do not significantly vary before a regime change. Thus, while focusing only on total expenditure does not uncover the effects of democratization, considering detailed categories of government expenditure enables us to understand how democratization changes governments' behaviors

Ethnic Diversity, Democracy, and Health: Theory and Evidence

This paper examines the relationship between ethnic composition, political regimes, and the quality of public policy. Specifically, based on the citizen-candidate model, we assume individuals who have heterogeneous policy preferences and investigate how ethnic diversity affects selection of a politician and the resulting policy choices in democratic and dictatorial regimes. In the theoretical analysis, our model derives (1) a negative relationship between ethnic diversity and the quality of public policy, both in a democracy with a dominant group and in a dictatorship, and (2) a non-monotonic relationship in a democracy without a dominant group. In the empirical examination, using health outcomes as the proxy for the quality of public policy, our theoretical results are supported by evidence from the data of 154 countries.Citizen-candidate model; Ethnic fractionalization; Infant mortality.

Laparoscopic Hepatectomy: Current State in Japan Based on the 4th Nationwide Questionnaire

Purpose. Since laparoscopic hepatectomy (LH) became covered by national health insurance in April 2010 in Japan, the numbers of applied cases and institutions performing it have increased and the indication has expanded. We surveyed the current state and safety of LH in Japan. Methods. A questionnaire survey was performed in 41 institutions related to the Japanese Endoscopic Liver Surgery Study Group and 747 institutions certified by the Japanese Society of Gastroenterological Surgery, and responses concerning all 2962 cases of LH performed by August 2011 were obtained. Results. The surgical procedure employed was hemihepatectomy in 234 (8%), segmentectomy in 88 (3%), left lateral segmentectomy in 434 (15%), segmentectomy in 156 (5%), and partial resection in 1504 (51%) cases. The approach was pure laparoscopy in 1835 (63%), hand-assisted laparoscopic surgery in 201 (7%), and laparoscopy-assisted surgery in 926 (31%). Regarding perioperative complications, surgery was switched to laparotomy in 59 (2.0%), reoperation was performed in 4 (0.1%), and surgery-related death occurred in 2 (0.07%). Intraoperative accidents occurred in 68 (2.3%), and postoperative complications developed in 94 (3.2%). Conclusions. When the selection of cases is appropriate, LH for liver diseases can be safely performed
