Economies of Scale and Utilization: An Analysis of the Multi-Plant Generation Costs of the Electricity Commission of New South Wales, 1970/71–1984/85*

We examine the average costs of electricity generated in NSW at the site level employing a new simultaneous-equations model approach Further, we argue that costs depend principally on unit size and capacity utilization We reinterpret capacity utilization as a compositional variable which is a continuous proxy for the (inverse of) the intensity of demand for electricity, thus partially addressing the multi-product nature of electricity. Low capacity utilization corresponds to intense demands and hence peaking output We find that costs per kWh, as conventionally measured, are highly sensitive to the degree of capacity utilization but less so to unit size (scale). The results emphasize the need for tine-related pricing     

The Effect of Subsidized Housing on Values of Adjacent Housing

This is a case study of the effect of subsidized housing on the value of adjacent non-subsidized housing. Four townhouse clusters in Fairfax County, Virginia, were selected for study because of the high degree of homogeneity between clusters. The clusters are all in the same community but vary in distance from subsidized housing. Sale prices were analyzed using a regression model which included distance from subsidized housing as an independent variable. Based on the results of the regression analysis, the authors conclude that the subsidized housing had a negative impact on the values of adjacent properties.     

Nurse shortage or nursing shortage: have we missed the real problem?

Many strategies have been used to solve the nurse shortage. The shortage of nurses has in many ways alerted us to the need to provide safe and efficient care using the latest technology. Nursing needs to adopt, refine, and use this technology so the impact of the nursing shortage is just another statistic and not a disruptive and costly threat to the public.     

Optimal Welfare-to-Work Programs

A Welfare-to-Work (WTW) program is a mix of government expenditures on various labour market policies targeted to the unemployed ( e.g. unemployment insurance (UI), job search monitoring (JM), social assistance (SA), wage subsidies). This paper provides a dynamic principal–agent framework suitable for analysing chief features of an optimal WTW program, such as the sequence and duration of the different policies, the dynamic pattern of payments along the unemployment spell, and the emergence of taxes/subsidies upon re-employment. The optimal program endogenously generates an absorbing policy of last resort ("social assistance") characterized by a constant lifetime payment and no active participation by the agent. Human capital depreciation is a necessary condition for policy transitions to be part of an optimal WTW program. The typical sequence of policies is quite simple: the program starts with standard UI, then switches into monitored search and, finally, into SA. The optimal benefits are decreasing during unemployment insurance and constant during both JM and SA. Whereas taxes (subsidies) can be either increasing or decreasing with duration during UI, they must decrease (increase) during a phase of JM. In a calibration exercise, we use our model to analyse quantitatively the features of the optimal program for the U.S. economy. With respect to the existing U.S. system, the optimal WTW scheme delivers sizeable welfare gains to unskilled workers because the incentives to search for a job can be retained even while delivering more insurance and using costly monitoring less intensively.     

The Employment Effects of Faster Payment: Evidence from the Federal Quickpay Reform

We study the impact of Quickpay, a reform that permanently accelerated payments to small business contractors of the U.S. government. We find a strong direct effect of the reform on employment growth at the firm level. However, we document substantial crowding out of nontreated firms' employment within local labor markets. While the overall net employment effect is positive, it is close to zero in tight labor markets. Our results highlight an important channel for alleviating financing constraints in small firms, but emphasize the general-equilibrium effects of large-scale interventions, which can lead to lower aggregate outcomes depending on labor market conditions.     

A practical solution to the problem of ultimate ruin probability

Abstract

It was the Swiss actuary Chr. Moser who, in lectures at Bern University at the turn of the century, gave the name “self-renewing aggregate” to what Vajda (1947) has called the “unstationary community” of lives, namely where deaths at any epoch are immediately replaced by an equivalent number of births. It was Moser too (1926) who coined the expression “steady state” for the stationary community in which the age distribution at any time follows the life table (King, 1887). With such a distinguished actuarial history, excellently summarized by Saxer (1958, Ch. IV), it behoves every actuary to know at least the definitions and modus operandi of today's so-called renewal (point), or recurrent event, processes.
