Switching the lights off: The impact of energy tariff increases on households in the Kyrgyz Republic

This paper describes an analysis of the impact that higher energy tariffs would have on households in the Kyrgyz Republic using micro-data from the 2009 Kyrgyz Integrated Household Survey. This analysis was conducted to determine which households would be most affected by higher energy tariffs and to what extent mitigation measures, such as lifeline tariffs or direct cash transfers, might lessen the impact for poor and vulnerable households. The analysis focused on first-order effects and used benefit incidence analysis and static micro-simulation to estimate the expected costs and benefits of higher energy prices and the corresponding mitigation measures. The results suggest that both the type of energy and the level of connectedness matter. Increasing tariffs for thermal power used for central heating and hot water mainly affects richer households in urban areas. Reducing implicit electricity subsidies affects the entire population due to nearly complete country coverage with electricity connections. Both lifeline tariffs and direct cash transfers could mitigate the effect of higher electricity tariffs at lower costs than universal subsidies.     

Individual preferences for public education spending: Does personal income matter?

Standard redistributive arguments suggest that the impact of household income on preferences for public education spending should be negative, because wealthier families are likely to oppose the redistributive effect of public funding. However, the empirical evidence does not confirm this prediction. This paper addresses this ‘puzzle’ by focusing on the role of the inclusiveness of the education system and the allocation of public spending between tiers of education in shaping the impact of income on preferences. By using data from the International Social Survey Programme (2006), we show that, when access to higher levels of education is restricted (low inclusiveness) and when the share of public spending on tertiary education is high, the poor are less likely to support public education spending. This result suggests that reforming the education system towards greater inclusiveness might contribute to increase political backing for public investment in education from the relatively poor majority of the population.     

The Distributive and Labor Supply Impact of the Minimum Insertion Income: The Case of Italy

This paper analyzes the redistributive and labor supply effects of extending at national level the Minimum Insertion Income, introduced experimentally in 1999 in some Italian municipalities. We develop a behavioral microsimulation tax-benefit model that allows for simultaneous labor supply decisions by household members, endogenous choice between dependent employment and self-employment, complete representation of the current Italian tax-benefit system. The results show a positive impact on both inequality and poverty, while overall labor supply reduces. On average magnitude of labor supply disincentive is small for married individuals, relatively larger for single persons and, within this category, for women than men.     

Environmental regulation and investment: Evidence from European industry data

This paper contributes to the empirical literature on the effects of environmental regulation on investment. In particular, we ask whether and how strongly an industry's investment responds to stringency in environmental regulation. Environmental regulation is measured as (i) an industry's total current expenditure on environmental protection, and (ii) a country-industry's revenue from environmental taxes. Focusing on European data of manufacturing industries between 1998 and 2007, we estimate the differential impact of environmental stringency on four types of investment: gross investment in tangible goods, in new buildings, in machinery, and in ‘productive’ investment (investment in tangible goods minus investment in abatement technologies). Both environmental variables enter positively, and their quadratic terms exhibit significantly negative parameter estimates. This, in turn, indicates a positive but diminishing impact of environmental regulation on investment.     

THE ESTIMATION OF THE INCIDENCE OF EMPLOYER CONTRIBUTIONS TO SOCIAL SECURITY IN JAPAN*

The present paper estimates the incidence of the employer portion of social security contributions in Japan. One of the purposes of the paper is to examine whether the employer portion is shifted entirely or partly in many industrialized countries. The paper concludes, based on our estimation method, that there is very little apparent backwards shifting on to employees and, therefore, employers bear nearly all of their portion of social security contributions. Firms in Japan could use their contributions to social security for other purposes to reduce the financial burden on firms.     

Taxation and the asymmetric adjustment of selected retail energy prices in the UK

This paper investigates the adjustment of the prices of four key petroleum products in the UK following changes in the price of crude oil. We find significant evidence that the pre-tax prices of diesel, kerosene, and gas oil adjust more rapidly in an upward than a downward direction, but that the pre-tax price of unleaded petrol adjusts symmetrically. However, these patterns are obscured at the pump once one accounts for fuel duty and value-added tax, raising the possibility that firms can use the tax system to conceal rent-seeking behaviour.     

Does early bird catch the worm or a lower GPA? Evidence from a liberal arts college

Research in psychology has shown that early morning classes are not conducive to learning because of the peculiar sleep cycles of adolescents and young adults that cause them to be especially groggy in the morning. Our study examines the relationship between the times that classes are offered and the grades that students in these classes earn at a highly selective liberal arts college. Our main findings are that morning classes are harmful for student achievement. Grades are especially lower for classes that were scheduled at 8 am and 9 am. Moreover, while students of both genders are adversely affected by early morning courses, the effects are particularly pronounced for male students. This institution assigns students randomly to different sections of the same course, thus creating a quasi-natural experiment and enabling us to control for unobserved characteristics of students. In addition, we include student and faculty fixed effects.     

Differences by mother’s education in the effect of childcare on child obesity

Previous studies have found adverse effects of maternal employment on child obesity for higher educated mothers. Using a quasi-structural model, we find additionally a lower risk of obesity for children of less educated mothers with increased time in non-parental childcare.     

Does health insurance matter? Evidence from China’s urban resident basic medical insurance

In 2007, China launched a subsidized voluntary public health insurance program, the Urban Resident Basic Medical Insurance (URBMI), for urban residents without formal employment. We estimate the impact of the URBMI on health care utilization and expenditure by a fixed effects approach with instrumental variable correction, using the 2006 and 2009 waves of the China Health and Nutrition Survey. We explore the time variation of program implementation at the city level as the instrument for individual enrollment. We find that this program has significantly increased the utilization of formal medical services, including both outpatient care and inpatient care, but it has not reduced total out-of-pocket health expense. We also find that this program has improved medical care utilization more for children, members of the low-income families, and the residents in the relatively poor western region.     

Public and Private Education in an Integrated Europe: Studying to Migrate and Teaching to Stay?

This paper investigates public and private choices between internationally applicable and country‐specific education when graduates are mobile. Human capital depends on innate skills and study effort with either type of education. It is shown that national governments provide too few students with internationally applicable education, and too many with country‐specific education. This effect is mitigated, but not entirely eliminated, by the introduction of a graduate tax, according to which graduates are required to pay part of their taxes to the country where they received their education, regardless of residence. However, private educational choices are socially optimal with suitably differentiated tuition fees.
