Projecting soviet energy requirements using a vintage capital model

A Solow-type vintage capital model with capital utilization is used to estimate the long-term average embedded rate of improvement in energy efficiency of Soviet fixed-capital commissionings: 2.6% per year. The results are combined with planned Soviet capital stock growth to forecast cap Soviet energy requirements through 1990. The implied Soviet capital utilization goals call for greater energy savings than have been achieved in the past. The results also identify an upper bound for rates of hidden inflation contained in Soviet capital commissionings data. It appears an estimate such as S. Cohn's 1% (Soviet Stud. 33, 2:269–299, 1981) is far more likely than A. Nove's 6 to 7% (Soviet Stud. 33, 1:142–145, 198 1).     

How and why transition made income inequality increase in urban Russia: A local study

Using sample surveys from the city of Taganrog in 1989 and 2000, we investigate household income, its composition, and its distribution in urban Russia. Income inequality increased greatly as real income at the lowest part of the distribution decreased considerably. Earnings are more concentrated in the upper part of the income distribution in 2000 than in 1989. For many households, public transfers, allowances, private transfers, or subsidiary earned income prevented income from falling further. However, Russia did not inherit from its Soviet past an efficient progressive tax system or programs to protect jobless workers and households facing severe drops in income.

Local financial benefits of rain forests: comparative evidence from Amerindian societies in Bolivia and Honduras

Researchers generally express the local value of tropical rain forests in dollars/ha/year. The approach is problematic because it produces low values to local users, underestimating the importance of the forest expressed as a share of household consumption or earnings. Here we contribute to valuation studies of rain forests by estimating the financial importance of the forest measured in three ways: (1) the contribution of forests to annual household consumption and (2) earnings; and (3) the value of a hectare of rain forest to villagers measured through the biological goods consumed and sold. We collected panel data on consumption and earnings from 81 households in four villages of two Amerindian societies in two nations (Tsimane’, Bolivia; Tawahka, Honduras). Analyses suggest: (1) forests account for a large share of household consumption (median 38.5%; range 14.65–53.11%); (2) forests contribute more to household consumption than to household earnings (median 22.69%; range 16.56–44.81%); (3) the relative contribution of forests to household consumption and earnings falls among villages closer to towns; and (4) the range of values/year of rain forest/ha is US$7.10–9.70 using 1999 dollars or US$18.46–46.56 using purchasing power parity indexes, below previous estimates. Results show much variation in forest values; valuation methods and stakeholder perspectives affect the variation. Given the variation, a useful strategy to promote forest conservation would transfer income to villagers to compensate them for non-local forest values.     

Precautionary saving under liquidity constraints: Evidence from rural Pakistan

This paper investigates precautionary saving under liquidity constraints in Pakistan using household panel data. In particular, while it estimates Kimball's [Kimball, M.S. Precautionary saving in the small and in the large. Econometrica 1990; 58; 53–73.] prudence parameter based on a framework that is similar to Dynan [Dynan, K.E. How prudent are consumers? Journal of Political Economy 1993; 101; 1104–1113.], this study deviates from the framework by explicitly considering liquidity constraints, as in Zeldes [Zeldes, S.P. Consumption and liquidity constraints: an empirical investigation. Journal of Political Economy 1989; 97; 305–346.]. By doing so, this paper attempts to differentiate the standard precautionary saving caused by uncertainty from that caused by liquidity constraints. Furthermore, endogenous liquidity constraints are used in order to resolve issues of selection biases. We find substantial evidence of the presence of precautionary saving in Pakistan. More specifically, the estimated prudence is significantly higher for liquidity-constrained households as compared with unconstrained ones. The finding suggests that the precautionary saving motives appear stronger when households see that their access to credit markets is limited.     

EASY MONEY OR HARD TIMES? HEALTH AND 401(k) LOANS

Rising health care costs and declining personal savings rates are nearly synonymous with household medical debt. For some, defined contribution (DC) retirement savings plans provide a ready source of funds to meet these medical debts. We examine whether health status and health insurance coverage predict the likelihood of having a DC loan using data from the Federal Reserve's triennial Survey of Consumer Finances (SCF) from 1989 to 2007. We find that poor health raises the likelihood that a household will borrow from their DC plans, even controlling for other forms of debt, access to credit, and whether households are covered by health insurance. Our estimates of the amount of the DC loan, taking selection effects into account, indicate that DC loan amounts are also influenced by health status; those with poor health borrow more from their DC plans. Apart from health status, once a household decides to borrow from their retirement funds, race and education also influence how much to borrow. We argue that public policy can improve the long‐term financial retirement security of households by offering more opportunities to save for medical emergencies, while cautiously maintaining the opportunity to borrow from DC plans.

Poverty, inequality, and growth in urban China, 1986–2000

Although urban China has experienced spectacular income growth over the last two decades, increases in inequality, reduction in social welfare provision, deregulation of grain prices, and increases in income uncertainty in the 1990s have increased urban poverty. Using a large repeated cross section household survey from 1986 to 2000, this study maps the changes in income, inequality, and poverty over the fifteen-year period and investigates the determinants of poverty. We find that the increase in poverty in the 1990s is associated with the increase in the relative food price and the need to purchase items that were previously provided free or at highly subsidized prices by the state, i.e., education, housing and medical care. In addition, the increased saving rate of poor households, which is due to an increase in income uncertainty, contributes significantly to the increase in poverty measured in terms of expenditure.

Cost Savings of Contracting Out Refuse Collection

The article discusses the possible cost savings of contractingout refuse collection in the Netherlands. Our findings indicate that similar to foreigneconometric studies cost savings ofapproximately 15–20% apply to the Netherlands.Moreover, compared with the existing literature we show thatdifferent production technologies apply to internal municipal waste collection units and externalrefuse collection firms. Different cost functions have to be estimated for the sub-samples.Though significant cost savings exist on contracting out wastecollection, households will not experience these cost savings on a one to one basis. Privaterefuse collection firms must pay VAT while public entities are exempted. Thus, the fiscal systemhinders a more pronounced role for private refuse collection firms.     

Government spending, capital accumulation and the optimal policy rule: The role of public service capital

In this paper, we modify the Djajić [Djajić, S., 1987. “Government Spending and the Optimal Rates of Consumption and Capital Accumulation,” Canadian Journal of Economics 20, 544–554.] model in such a way that government consumption expenditure provides utility to households via the total stock of government services rather than the government consumption flow alone. By using such a framework, we show that the optimality condition for the public service capital stock is the marginal rate of substitution between public service capital and consumption that equals the intertemporal marginal rate of transformation between the two goods. In addition, we show that the relationship between private consumption and public service capital in a household's utility plays an important role in determining the transitional behavior of relevant variables. We also examine the second-best government consumption expenditure policy. By contrast, in the standard flow specification, e.g., Turnovsky and Brock [Turnovsky, S.J. and Brock, W.A., 1980. “Time Consistency and Optimal Government Policies in Perfect Foresight Equilibrium,” Journal of Public Economics 13, 183–212.], Ihori [Ihori, T., 1990. “Government Spending and Private Consumption,” Canadian Journal of Economics 23, 60–69.], and Turnovsky and Fisher [Turnovsky, S.J. and Fisher, W.H., 1995. “The Composition of Government Expenditure and its Consequences for Macroeconomic Performance,” Journal of Economic Dynamics and Control 19, 747–786.], the second-best government consumption expenditure is decided on the basis that the marginal utility of consumption is equal to the discounted sum of the marginal utility of the government's flow spending.     

Insurance of Household Risks and the Rebalancing of the Chinese Economy: Health Insurance,Health Expenses and Household Savings

This paper studies the effects of a public insurance system, the New Cooperative Medical Scheme (NCMS) on household savings in rural China. We develop a theoretical model in which we explain the impact of health insurance on savings through the impact of health insurance on out‐of‐pocket (OOP) health expense given the household level of wealth and seriousness of illness. We test the model empirically using data from the China Health and Nutrition Survey. We run endogenous and exogenous quantile regressions to evaluate the effects of NCMS participation on the distributions of household savings and OOP health expense. The impact of NCMS varies with the seriousness of illness. The NCMS induces an increase in OOP health expense for mild illness and, inversely, a decrease in health payments for more serious illnesses. The NCMS also leads to a higher incidence of catastrophic healthcare spending. The impact of the NCMS, given a certain state of illness, also varies with the household level of wealth. Poor households face health expense for both mild and serious illnesses. As the NCMS has opposite effects on the OOP expense for these two kinds of illness, we observe no effect on poor households’ precautionary savings. Because the decrease in OOP health expense for mild illness is larger for less poor households, the NCMS induces a decrease in their savings. For the most affluent households, the higher decrease in OOP spending on most moderate illness is dominated by a sharp increase in catastrophic expense, causing an increase in savings. To significantly reduce household savings and enhance household consumption, the NCMS has to offer better coverage against both serious and catastrophic health risks.     

Ethnic conflict and economic disparity: Serbians and Albanians in Kosovo

Using the Living Standards Measurement Study (LSMS) household survey from post-conflict Kosovo, we investigate the comparative economic well-being of Serbs and Albanians. An Oaxaca decomposition shows Serb households are both better endowed with income generating characteristics, such as education, and receive higher returns to these characteristics than Albanian households. Despite these advantages, Serb households have lower living standards, on average, than Albanian households. Most of the difference in living standards between Serb and Albanian households is due to unobserved non-economic factors. This result has serious implications for the political economy of policymaking in post-conflict Kosovo. Journal of Comparative Economics 34 (4) (2006) 754–773.     

The savings behavior of migrant workers : Turkish workers in W. Germany

This paper presents an analysis of savings behavior of Turkish households residing in W. Germany using survey data. It is found that there exists a statistically significant difference in the savings behavior of households who migrate from urban areas of Turkey and those who migrate from rural areas. The estimated savings function is non-linear with respect to household income. While education and the occupation of the head of household do not have statistically significant impacts on the savings of either group, age of the household's head has a statistically significant impact on the savings behavior of both groups.     

Consumption,habit formation,and savings: Evidence from a rural household panel survey

Protecting consumption from the effects of uninsured risk is vital for rural farming households, who tend to be poor and live close to subsistence level. Income uncertainty and habit formation play important roles in the consumption and savings. Variability in weather conditions has a strong linkage with variability in agricultural income in developing countries. This study analyzes consumption and saving decisions of rural farm households in India. Using household panel data for 4 years, we estimated consumption equation accounting for habit formation under income uncertainty. Our findings suggest an evidence for habit formation among rural households. Additionally, we found that both annual and seasonal weather risks significantly influence savings among rural households. Findings from this study also suggest a robust and vibrant farm economy and that the nonfarm economy could contribute to the economic well‐being of rural farming households.     

不确定性下农村家庭食品消费的"习惯形成"检验

本文利用"习惯形成"(habit formation)假说来研究中国家庭食品消费行为的特征,并首次利用1989—2006年农村家庭微观面板数据进行实证分析,从而试图给出近年来农村居民储蓄率持续偏高、消费倾向持续偏低的一种新解释。对动态面板模型的系统广义矩估计结果显示,农村居民家庭的食品消费有显著的习惯形成效应,这一效应即使在考虑了家庭的"预防性动机"之后仍然是稳健的,并且它对消费的边际影响比预防性动机更为重要。但是本文估计出的"习惯形成"参数比用总量数据得到的习惯形成参数要小。     

Does 401(k) eligibility increase saving?: Evidence from propensity score subclassification

By comparing 401(k) eligible and ineligible households’ wealth, this paper estimates that, on average, about one half of 401(k) balances represent new private savings, and about one quarter of 401(k) balances represent new national savings. Responses to eligibility vary considerably, however, with households who normally save the most largely contributing funds they would have saved anyway. This paper improves on previous research by: (1) employing propensity score subclassification to control more completely for observed household characteristics, (2) controlling for more household characteristics, including several correlated with unobserved savings preferences, and (3) adjusting the observed measure of households’ wealth to reduce measurement error.     

The Corporate State,Economic Performance,and Social Policy

We use the Survey of Consumer Finances to analyze changes in U.S. household debt between 1989 and 2013. We focus on how income and debt levels have changed, and what this means for future economic growth and living standards. Prior to the Great Recession, U.S. households had record high debt levels and record low savings rates. Highly leveraged consumption boosted economic growth. However, large debt burdens have led many families to deleverage. Our study finds that deleveraging has been insufficient. Although debt payments have fallen relative to household income, this is mainly due to low interest rates. Debt levels, especially for home mortgages, remain high by historical standards and portend continued stagnation due to lower consumer spending.     

Uncertain Pension Income and Household Saving

This paper investigates the relationship between household saving and pensions, and estimates both the displacement effect of pensions on private saving and the precautionary saving effect due to uncertainty in pension income. I estimate the savings equation implied by a simple life‐cycle model featuring income uncertainty using survey data for Dutch households, with subjective expectations on pension benefits and uncertainty. Exploiting exogenous variation due to pension fund performance, I find that households save significantly more due to uncertainty in pension income. Not controlling for uncertainty biases the estimated displacement effect of pensions on private savings towards zero.     

Testing Prediction Performance of Poverty Models: Empirical Evidence from Uganda

This paper examines the performance of a method of predicting poverty rates. Because most developing countries cannot justify the expense of frequent household budget surveys, additional low‐cost methods have been developed and used. The prediction method is based on a model linking the proportion of poor households to suitable explanatory variables (consumption proxies). These consumption proxies are variables that can be collected at much lower cost through smaller annual surveys. Several applications have shown that such models can produce poverty estimates with confidence intervals of a similar magnitude to the poverty estimates from the household budget surveys. There is, however, limited evidence of how well the methods perform out‐of‐sample. A series of seven household budget surveys conducted in Uganda in the period 1993–2005 allows us to test the prediction performance of the model. We test the poverty models by using data from one survey to predict the proportion of poor households in other surveys, and vice versa. The results are encouraging, as all models predict similar poverty trends. Although in most cases the predictions are precise, sometimes they differ significantly from the poverty level estimated from the survey directly.     

Debt Overhang and Barter in Russia

This paper develops a model in which costly barter is used by firms to protect working capital against outside creditors. Although creditors could agree to postpone debt payments and to avoid destroying the firm's working capital, if the firm cannot commit not to divert cash ex post, the outcome of renegotiation still provides ex ante incentives to use barter. We show that the greater is the debt overhang, the more likely is the use of barter, with and without the possibility of debt restructuring. Empirical evidence from Russian firm-level data is shown to be consistent with the model's predictions. J. Comp. Econ., December 2002, 30(4), pp. 635–656.

Do Consumers Learn from Their Own Experiences?

It is natural to think that a household may learn from its own experiences and subsequently increase savings. This paper tests empirically the hypothesis that Japanese households learn from their experiences of large expenditure and increase their targets for precautionary savings after such experiences. The results imply that households raise their targets for precautionary savings by 4–5 percent of annual income in response to such experiences. Moreover, data are consistent with the argument that targets for savings affect actual savings. Assuming this holds, the results in this paper suggest that consumers may increase their actual savings following large expenditure.     

The tenability of the CIA estimates of Soviet economic growth

This paper evaluates the tenability of the Central Intelligence Agency (CIA) estimates of Soviet economic growth during 1950–1980, published in December 1982. The evaluation involves applying the CIA methodology used in making these estimates to estimate economic growth in the Federal Republic of Germany and the United States and then comparing the results with the official estimates of the respective countries themselves. Use of the CIA methodology understates substantially the growth of both the West German and the U.S. economies, which raises the possibility that it also understates Soviet economic growth.
