How is the worker’s weekly hour related to wage over the life cycle? The U.S. evidence

The current study estimates the relationship between weekly hours and weekly wage over the life cycle of a representative sample of workers. Recognizing the endogeneity of these two variables, the study estimates both equations in a simultaneous equations framework and demonstrates that the relationship between weekly hours and weekly wage is not uniform over the worker’s life cycle. These two variables are negatively related when the workers are young and have a positive relationship when they are matured adults. This conclusion remains valid for both men and women. Our robustness check further confirms that workers respond to wage increases differently at different stages of their working career. This has interesting policy implications. Any policy to influence the worker’s hours decision through wage incentive must consider the stage of his/her working career.     

Crime rates,male youth unemployment and real income in Australia: evidence from Granger causality tests

This article applies Granger causality tests to examine the relationship between seven different categories of property crime and violent crime against the person, male youth unemployment and real male average weekly earnings in Australia from 1964 to 2001 within a cointegration and vector error correction framework. It is found that fraud, homicide and motor vehicle theft are cointegrated with male youth unemployment and real male average weekly earnings. However, there is no evidence of a long-run relationship between either break and enter, robbery, serious assault or stealing with male youth unemployment and real male average weekly earnings.     

Cost-efficacy analysis of biological treatments in psoriasis: an 18-month assessment

Summary

This study compared the cost-efficacy of the following approved biological treatment strategies for plaque psoriasis over 18 months: (1) alefacept 15 mg intramuscularly weekly for two 12-week courses; (2) efalizumab 1 mg/kg subcutaneously (SC) weekly; and (3) etanercept 50 mg SC twice weekly for 12 weeks followed by a maintenance dose of 50 mg weekly. Direct utilisation-related costs included drug costs, office fees, injection fees and costs incurred due to adverse events and laboratory monitoring. Efficacy was based on response rates from large-scale clinical trials. At 18 months, total utilisation-related costs for alefacept, efalizumab and etanercept were $26,667, $33,365 and $32,962, respectively. Cost-efficacy, calculated using the corresponding response rates for the three therapies, was comparable ($66,669, $75,828 and $61,041, respectively). Thus, for patients with moderate to severe psoriasis who have responded to therapy, two 12-week courses of alefacept 7 months apart, or weekly maintenance treatment with efalizumab or etanercept, resulted in comparable total cost-efficacy.     

Does microtherm boost pharmaceutical companies’ market capitalization returns?

The purpose of this study was to survey the relationship between the temperature factors and market capitalization returns of pharmaceutical companies by analysing both the daily and weekly frequency data in Taiwan. The threshold regression model with the GJR-GARCH process was applied for examination in this study; we found that pharmaceutical companies’ market capitalization returns could be boosted after exposure to extremely low temperatures for a period of time. Besides, the delayed effect of cold weather is demonstrated to exist. This phenomenon can be illustrated by epidemiological evidence-related mental factors, not by traditional behavioural finance. Moreover, lower weekly average temperatures are beneficial for investors to gain weekly pharmaceutical companies’ market capitalization returns. We are of the opinion that our findings offer an insightful suggestion for investors to buy pharmaceutical stocks at an opportune moment.     

To defer or not defer? UK state pension and work decisions in a lifecycle model

The UK state pension (which depends only on age) includes an option to defer take up which yields either a subsequent lump sum or higher weekly pension. We analyse the joint decisions on pension deferral and intertemporal labour supply/participation in a lifecycle setting. We show that deferral is purely a financial decision, but the impact of deferral on work decisions depends on preferences, wage rates, non-labour income and initial wealth. To exactly characterize this, we use a quasilinear utility function and provide calibrated simulations. We also discuss the choice between a lump sum or increased weekly pension.     

On hourly wages and weekly earnings in the current population survey

This paper examines hourly wages and weekly earnings in the Outgoing Rotation Group (ORG) and the March Supplement of Current Population Survey (CPS) from 1998 to 2004. The findings suggest that the ORG contains less errors than the March CPS, and that weekly earnings contain less errors than hourly wages. The paper further finds that earnings differ systematically in the ORG and in the March CPS by gender and education levels.     

Extending working hours: why not work 42 h rather than 38?—a CGE analysis for Germany

Faced with a record level of unemployment, the present debate in Germany is to extend the weekly hours of work. In this paper the employment effects of an economy-wide increase in weekly hours are quantified on the basis of a computable general equilibrium model for different specifications of the wage setting rule and the use of additional policy-induced public income. The simulation results back the argument of the opponents of longer working time that not more jobs will be created. However, when the higher tax revenues from GDP growth are used to reduce social security contributions, then the claim of the proponents that more jobs will be created can be supported.     

Measuring the effectiveness of US monetary policy during the COVID-19 recession

The COVID-19 recession that started in March 2020 led to an unprecedented decline in economic activity across the globe. To fight this recession, policy makers in central banks engaged in expansionary monetary policy. This paper asks whether the measures adopted by the US Federal Reserve (Fed) have been effective in boosting real activity and calming financial markets. To measure these effects at high frequencies, we propose a novel mixed frequency vector autoregressive (MF-VAR) model. This model allows us to combine weekly and monthly information within a unified framework. Our model combines a set of macroeconomic aggregates such as industrial production, unemployment rates, and inflation with high-frequency information from financial markets such as stock prices, interest rate spreads, and weekly information on the Fed's balance sheet size. The latter set of high-frequency time series is used to dynamically interpolate the monthly time series to obtain weekly macroeconomic measures. We use this setup to simulate counterfactuals in absence of monetary stimulus. The results show that the monetary expansion caused higher output growth and stock market returns, more favorable long-term financing conditions and a depreciation of the US dollar compared with a no-policy benchmark scenario.     

German stock market dynamics

This article estimates generalized ARCH (GARCH) models for German stock market indices returns, using weekly and monthly data, various GARCH specifications and (non)normal error densities, and a variety of diagnostic checks. German stock return series exhibit significant levels of second-order dependence. Our results clearly demonstrate that for both weekly as well as monthly return series the Student-t distribution is superior to the standard normal distribution. In particular, the estimated GARCH-t models appear to be reasonably successful in accounting for both observed leptokurtosis and conditional heteroskedasticity from German stock return movements.     

A Downward‐Sloping Labor Supply Curve: The Case of Peru

The author finds evidence of a downward‐sloping labor supply curve for urban areas in Peru from cross‐sectional household data for 2002 and pooled data for available years from 1985 to 2000. Individuals respond to lower hourly earnings with an increase in the quantity supplied of work hours. This behavior would help to explain the increasing trend in average work hours in Peru (this average for male workers in Lima, the capital city, rose from 50.5 to 53.9 weekly hours between 1985 and 2000; meanwhile, 33.4% of workers had weekly schedules above 60 hours in 2002). Another finding is the increase in hours supplied due to pressure from the more numerous cohorts recently entering the Peruvian labor market.     

Unemployment compensation and episodes of nonemployment

This paper examines the influence of unemployment insurance (UI) on the length of nonemployment spells experienced by young workers. The analysis introduces a flexible duration model to estimate the effects of the weekly benefit amount and weeks of eligibility on the amount of time spent between jobs by men, distinguishing between the experiences of UI and non-UI recipients. The empirical findings suggest three conclusions: (1) UI recipients experience longer spells of nonemployment than their non-UI recipient counterparts, at least up to the point of exhaustion of UI benefits; (2) the level of the weekly benefit amount does not significantly affect the length of nonemployment spells; and (3) increasing the number of weeks of eligibility offered by a UI program leads to longer episodes of nonemployment.     

Social security, retirement age and optimal income taxation

It is often argued that implicit taxation on continued activity of elderly workers is responsible for the widely observed trend towards early retirement. In a world of laissez-faire or of first-best efficiency, there would be no such implicit taxation. The point of this paper is that, when first-best redistributive instruments are not available, because some variables are not observable, the optimal policy does imply a distortion of the retirement decision. Consequently, the inducement of early retirement may be part of the optimal tax-transfer policy. We consider a model in which individuals differ in their productivity and their capacity to work long and choose both their weekly labor supply and their age of retirement. We characterize the optimal non-linear tax-transfer that maximizes a utilitarian welfare function when weekly earnings and the length of active life are observable while individuals' productivity and health status are not observable.     

A monetary valuation of individual religious behaviour: the case of prayer

The majority of the US population is religious. The value of a fundamental religious behaviour, prayer, is determined using the well-being valuation method. Theoretically appropriate Instrumental Variables (IV) are used to avoid bias in estimating the effects of household income and the frequency of prayer on well-being. The marginal value of an additional weekly prayer session for individuals already at the national mean is estimated to be $6550 per annum (2004 dollars). Praying at the frequency of the national mean of 8.1 prayer sessions weekly is valued at $53?055 (2004 dollars) per annum. This is larger than the median household income in the US in 2004: $44?684. This suggests that the perception of communion with God is highly valued by religious individuals.     

Optimal Pricing with Costly Adjustment: Evidence from Retail-Grocery Prices

In many theoretical models, it is assumed that there are costs associated with adjusting prices. In this paper, the existence, type, and magnitude of such costs are investigated empirically. A discrete-choice dynamic-programming model that nests fixed and variable costs is developed, and econometric estimates of the adjustment-cost function are obtained. The data used to implement the model consist of weekly retail prices and sales of three brands of saltine crackers sold by four chains of grocery stores in a small U.S. town. The study has several distinguishing characteristics. First, the data are highly disaggregate (at the level of brand and store). Second, variables are sampled at weekly intervals. Third, the model nests fixed- and variable-adjustment costs and can therefore determine their relative importance. Finally, the discrete-choice model is both structural and dynamic.     

Continuous prophylaxis with recombinant factor IX Fc fusion protein and conventional recombinant factor IX products: comparisons of efficacy and weekly factor consumption

Background: Continuous prophylaxis for patients with hemophilia B requires frequent injections that are burdensome and that may lead to suboptimal adherence and outcomes. Hence, therapies requiring less-frequent injections are needed. In the absence of head-to-head comparisons, this study compared the first extended-half-life-recombinant factor IX (rFIX) product—recombinant factor IX Fc fusion protein (rFIXFc)—with conventional rFIX products based on annualized bleed rates (ABRs) and factor consumption reported in studies of continuous prophylaxis.

Methods: This study compared ABRs and weekly factor consumption rates in clinical studies of continuous prophylaxis treatment with rFIXFc and conventional rFIX products (identified by systematic literature review) in previously-treated adolescents and adults with moderate-to-severe hemophilia B. Meta-analysis was used to pool ABRs reported for conventional rFIX products for comparison. Comparisons of weekly factor consumption were based on the mean, reported or estimated from the mean dose per injection.

Results: Five conventional rFIX studies (injections 1 to >3 times/week) met the criteria for comparison with once-weekly rFIXFc reported by the B-LONG study. The pooled mean ABR for conventional rFIX was slightly higher than but comparable to rFIXFc (difference=0.71; p?=?0.210). Weekly factor consumption was significantly lower with rFIXFc than in conventional rFIX studies (difference in means?=?42.8–74.5?IU/kg/week [93–161%], p?Conclusion: Comparisons of clinical study results suggest weekly injections with rFIXFc result in similar bleeding rates and significantly lower weekly factor consumption compared with more-frequently-injected conventional rFIX products. The real-world effectiveness of rFIXFc may be higher based on results from a model of the impact of simulated differences in adherence.     

Trading imbalances and the law of one price

We study trading and prices of Chinese (mainland)/Hong Kong dual-listed shares. Relative prices can diverge by a factor of two and exhibit significant variation over time. Order imbalances explain contemporaneous changes in relative prices at daily and weekly frequencies.     

Exchange rate volatility and the mixture of distribution hypothesis

This study sheds new light on the mixture of distribution hypothesis by means of a study of the weekly exchange rate volatility of the Norwegian krone. In line with other studies we find that the impact of information arrival on exchange rate volatility is positive and statistically significant, and that the hypothesis that an increase in the number of traders reduces exchange rate volatility is not supported. The novelties of our study consist in documenting that the positive impact of information arrival on volatility is relatively stable across three different exchange rate regimes, and in that the impact is relatively similar for both weekly volatility and weekly realised volatility. It is not given that the former should be the case since exchange rate stabilisation was actively pursued by the central bank in parts of the study period. We also report a case in which undesirable residual properties attained within traditional frameworks are easily removed by applying the log-transformation on volatilities.

Efficiency in the Forward Foreign Exchange Market: Weekly Tests of the Australian/US Dollar Exchange Rate January 1984-March 1987*

This paper examines the relationship which exists between the spot and forward Australian/US Dollar exchange rates for one-, three-and six-month contracts using weekly data over the period January 1984—March 1987. The paper splits the forward premium into a component due to risk and one which is due to a forecasting error, and this analysis is suggestive of a time-varying risk premium.     

Effectiveness of One-Euro-Jobs: do programme characteristics matter?

Recent German labour market reforms introduced a large scale workfare programme called One-Euro-Jobs to activate welfare recipients and improve their employment prospects. In programme design leeway is left to regional actors. Using administrative data and Propensity Score (PS) matching, this article investigates the association between programme design and effectiveness, so as to provide insight on how to increase programme effectiveness. First, effects of different types of One-Euro-Jobs according to planned duration and weekly working hours compared to ‘waiting’ are estimated. Second, programme types are compared directly to disentangle selection and programme effects. As expected lock-in effects are larger for participations with a longer planned duration, but not for those with longer weekly working hours. One-Euro-Jobs do not generally increase the employment prospects for East German men beyond 2 years after programme start and longer and more intensive participations even decrease employment prospects. In West Germany, One-Euro-Jobs generally increase the employment chances and longer participations lead to slightly greater employment opportunities roughly 2 years after programme start. The initial advantages of short participations decrease over time. Following these results, a reallocation of participants might improve programme effectiveness.     

The formation of expectations: Some evidence from weekly money supply forecasts

This paper investigates the expectations formation process of weekly money supply forecasts derived from survey data. The evidence indicates that forecaster's expectations are modelled best as regressive. Moreover, the results are unaffected by the October 1979 change in monetary operating procedures.
