Resource use: the complexity of time and energy management in clothing maintenance

The research study examined time management and energy consumption with respect to clothing care. The investigation analysed data and information obtained in the NE-113 Family Time-Use Study collected in 1977–1978. Differences were found between urban and rural households and among different states. Occupational types of home manager, day of the week, education and age of children were variables accounting for differences in clothing care activities. The results have significance for a better understanding of how modem households meet the demands of clothing care management.     

Investment Adjustment Costs: An Empirical Assessment

We evaluate the empirical evidence for costs that penalize changes in investment using U.S. industry data. In aggregate models, such investment adjustment costs have been introduced to help account for a variety of business cycle and asset market phenomena. So far no attempt has been made to estimate these costs directly at a disaggregated level. We consider an industry model with investment adjustment costs and estimate its parameters using generalized methods of moments. The findings indicate small costs associated with changing the flow of investment at the industry level. The weighted average of the industry elasticities with respect to the shadow price of capital, which depends inversely on the adjustment cost parameter, is eight times larger than the largest estimate reported in Levin et al. (2006) . We examine a variety of factors that may account for this discrepancy, but a substantial part of it remains unexplained. Our results therefore suggest that more caution is needed when giving policy advice that hinges on a structural interpretation of large investment adjustment costs.     

CONSUMER AWARENESS AND ACCEPTANCE OF FLAME RETARDANT TEXTILE PRODUCTS AND FLAMMABILITY LEGISLATION

The quest for flame retardance has witnessed a continual involvement of many diverse disciplines; especially concerned are those in the area of textiles and clothing. In this study, an instrument was developed to assess the subject's awareness of flame retardant textile products, cost and care practices of flame retardant fabrics, and attitude toward federal flammability legislation. The main objective of the study was to conduct a survey among 1500 consumers in a south-western city of the United States to determine if measures taken by the Consumer Product Safety Commission in regard to flame retardant items had been understood by the consumer. The study determined a need for extensive consumer education in the area of textile flammability to heighten awareness of flame retardant textile items and care practices. Exploration of other alternatives to mandated safety standards was recommended.     

Risk Overhang and Loan Portfolio Decisions: Small Business Loan Supply before and during the Financial Crisis

We estimate a structural model of bank portfolio lending and find that the typical U.S. community bank reduced its business lending during the global financial crisis. The decline in business credit was driven by increased risk overhang effects (consistent with a reduction in the liquidity of assets held on bank balance sheets) and by reduced loan supply elasticities suggestive of credit rationing (consistent with an increase in lender risk aversion). Nevertheless, we identify a group of strategically focused relationship banks that made and maintained higher levels of business loans during the crisis.     

House Prices and Government Spending Shocks

We show that dynamic stochastic general equilibrium (DSGE) models with housing and collateralized borrowing predict a fall in house prices following positive government spending shocks. By contrast, we show that house prices in the United States rise persistently after identified positive government spending shocks. We clarify that the incorrect house price response is due to a general property of DSGE models—approximately constant shadow value of housing—and that modifying preferences and production structure cannot help in obtaining the correct house price response. Properly accounting for the empirical evidence on government spending shocks and house prices using a DSGE model therefore remains a significant challenge.     

The Demand for Assets and Optimal Monetary Aggregation

This paper uses a highly disaggregated demand system to estimate the degree of substitutability among monetary assets and to address the issue of optimal monetary aggregation in the United States. We address the problems of dimensionality and nonlinearity, estimating a very detailed monetary asset demand system encompassing the full range of assets based on the locally flexible normalized quadratic expenditure function. We treat the concavity property as a maintained hypothesis and provide evidence consistent with neoclassical microeconomic theory. Statistical tests reject the appropriateness of the aggregation assumptions for all the money measures published by the Federal Reserve as well as for a large number of groupings suggested by earlier studies. This supports and reinforces Barnett's (2016) assertion that we should employ the broadest M4 monetary aggregate published by the Center for Financial Stability.     

The Consequences of Zakat for Capital Accumulation

The payment of zakat by the owners of wealth is one of the five pillars of Islam. Many countries operate with no enforcement of the obligation to pay, making zakat a form of voluntary redistribution. We analyze how zakat affects capital accumulation in a model that explicitly recognizes the voluntary nature of zakat. The voluntary payment is modeled using both warm glow and social custom frameworks. These are embedded within an overlapping generations model with heterogenous consumers and endogenous population growth. The results show that zakat can raise the capital–labor ratio when it is motivated by the warm glow but welfare can be nonmonotonic in the strength of the warm glow. In the social custom model, reduced participation can lead to a reduced capital–labor ratio as the rate of zakat is increased.
