Intertemporal Substitution in Labor Force Participation: Evidence from Policy Discontinuities

This paper presents new empirical evidence on intertemporal labor supply elasticities. We use administrative data on the census of private sector employees in Austria and variation from mandated discontinuous changes in retirement benefits from the Austrian pension system. We first present graphical evidence documenting delays in retirement in response to the policy discontinuities. Next, based on the empirical evidence, we develop a model of career length decisions. Using an estimator that exploits the graphical evidence, we estimate an intertemporal labor supply elasticity of 0.30; this relatively low estimate reflects that the disutility of labor supply rises relatively quickly with additional years of work.life-cycle labor supply, retirement decisions, intertemporal labor supply elasticity, policy discontinuities

Client-contractor bargaining on net present value in project scheduling with limited resources

The client-contractor bargaining problem addressed here is in the context of a multi-mode resource constrained project scheduling problem with discounted cash flows, which is formulated as a progress payments model. In this model, the contractor receives payments from the client at predetermined regular time intervals. The last payment is paid at the first predetermined payment point right after project completion. The second payment model considered in this paper is the one with payments at activity completions. The project is represented on an Activity-on-Node (AON) project network. Activity durations are assumed to be deterministic. The project duration is bounded from above by a deadline imposed by the client, which constitutes a hard constraint. The bargaining objective is to maximize the bargaining objective function comprised of the objectives of both the client and the contractor. The bargaining objective function is expected to reflect the two-party nature of the problem environment and seeks a compromise between the client and the contractor. The bargaining power concept is introduced into the problem by the bargaining power weights used in the bargaining objective function. Simulated annealing algorithm and genetic algorithm approaches are proposed as solution procedures. The proposed solution methods are tested with respect to solution quality and solution times. Sensitivity analyses are conducted among different parameters used in the model, namely the profit margin, the discount rate, and the bargaining power weights

School Sanitation in Underserved Urban Areas in India

This paper discusses how GIZ is supporting the Ministry of Urban Development in improving the sanitation situation for the urban poor. It selected 47 schools in five Indian cities to significantly improve the sanitation conditions, aiming to build awareness and capacity. All schools showed measurable improvements on school sanitation at the end of the project

OTC Derivatives Market in India: Recent Regulatory Initiatives and Open Issues for Market Stability and Development

The OTC derivatives markets all over the world have shown tremendous growth inrecent years. In the wake of the present financial crisis, which is believed to have beenexacerbated by OTC derivatives, increasing attention is being paid to analysing theregulatory environment of these markets. In this context, we analyse the regulatoryframework of the OTC derivatives market in India. The paper, inter alia, seeks toprove the point that the Indian OTC derivatives markets, unlike many otherjurisdictions, are well regulated. Only contracts where one party to the contract is anRBI regulated entity are considered legally valid in India. A good reporting systemand a post-trade clearing and settlement system, through a centralised counter party,has ensured good surveillance of the systemic risks in the Indian OTC market.From amongst the various OTC derivatives markets permitted in India, interest rateswaps and foreign currency forwards are the two prominent markets. However, byinternational standards, the total size of the Indian OTC derivatives markets stillremains small because credit default swaps were conspicuously absent in India untilnow. It appears that Indian OTC derivatives markets will grow fast once again afterthe present financial crisis is over. This research paper explores those open issues thatare important to ensure market stability and development. On the issue of the muchdiscussed competition between exchange-traded and OTC-traded derivatives, webelieve that the two markets serve different purposes and would contribute more torisk management and market efficiency, if viewed as complementary. Regarding theintroduction of new derivative products for credit risk transfer, the recentannouncement by the RBI that it would introduce credit default swaps is a welcomesign. We believe that routing of credit default swaps through a reporting platform andmanaging its post-trade activities through a centralised counterparty would providebetter surveillance of the market. Strengthening the position of the ClearingCorporation of India Ltd. (CCIL) as the only centralised counterparty for Indian OTCderivatives market and better supervision of the off-balance sheet business offinancial institutions are two measures that have been proposed to ensure the stabilityof the market.Derivatives and Over the Counter Market, Financial Institutions and Services and Government Policy and Financial Regulation

Does Indivisible Labor Explain the Difference Between Micro and Macro Elasticities? A Meta-Analysis of Extensive Margin Elasticities

Macroeconomic calibrations imply much larger labor supply elasticities than microeconometric studies. One prominent explanation for this divergence is that indivisible labor generates extensive margin responses that are not captured in micro studies of hours choices. We evaluate whether existing calibrations of macro models are consistent with micro evidence on extensive margin responses using two approaches. First, we use a standard calibrated macro model to simulate the impacts of tax policy changes on labor supply. Second, we present a meta-analysis of quasi-experimental estimates of extensive margin elasticities. We find that micro estimates are consistent with macro evidence on the steady-state (Hicksian) elasticities relevant for cross-country comparisons. However, micro estimates of extensive-margin elasticities are an order of magnitude smaller than the values needed to explain business cycle fluctuations in aggregate hours. Hence, indivisible labor supply does not explain the large gap between micro and macro estimates of intertemporal substitution (Frisch) elasticities. Our synthesis of the micro evidence points to Hicksian elasticities of 0.3 on the intensive and 0.25 on the extensive margin and Frisch elasticities of 0.5 on the intensive and 0.25 on the extensive margin.

The Effects of Increasing the Early Retirement Age on Employment of Older Workers

This paper studies the effects of a series of reforms of the public pension system in Austria in 2000 and 2004. An important element of the reforms was the increase in the early retirement age (ERA), which was phased in linearly over several cohorts. The empirical analysis, based on detailed administrative data, distinguishes between pension entries, which are mechanically affected by the ERA, and job exits, which reflect individual labor supply decisions. The paper presents four main findings. (1) The cohort-wise increase in the early retirement age led to pronounced shifts in the spike of pension entries at the cohort specific early retirement ages. (2) Job exits shifted in an almost parallel fashion, which leaves little room for additional substitution with other social insurance programs. (3) An important mechanism leading to increased employment is that individuals keep their pre-retirement jobs longer. (4) To quantify the effects of the reform on average retirement ages, we use a regression kink design that exploits the increasing slope in the ERA by birth cohorts and relates it to a corresponding linear increase in the labor force exit and pension claiming ages. We estimate that a one year increase in the ERA leads to a 0.4 year increase in the exit age and a 0.5 year increase in the claiming age
