We analyze the effect of being born in a recession on the mortality rate later in life in conjunction with social class. We use individual data records from Dutch registers of birth, marriage, and death certificates, covering the period 1815-2000, and we merge these with historical data on macro-economic outcomes and health indicators. We estimate duration models and inequality measures. The re...
Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of a stochastic fishery...
In this paper, an extensive report on the economy of Myanmar prepared in 1998 is supplemented by more recent reports as of fall 2002 (included as appendices). Dr. Dapice’s most recent papers on Myanmar can be accessed on Harvard Kennedy School’s Ash Center website. The economy of Myanmar is one of the poorest in South East Asia. Despite relatively rapidly growth during the 1990’s, per capita in...
The paper deals with the economic dispatch problem for a district heating system. The distribution network is modeled with a number of nodes and arcs, implying that time delays and restrictions in distribution capacity can be considered. A solution algorithm for the corresponding nonlinear optimization problem is proposed. The method is based on Lagrangian relaxation and exploits the relations ...
OBJECTIVE To explore the predictors of the quality of marriage of men with prostate cancer, as being diagnosed with prostate cancer affects the quality of life of the man and his partner, and while some aspects are known about the impact of the disease and its treatments on the man's quality of life, less is known about the marriage quality (MQ) in this new situation.

This paper investigates whether there has been a fundamental change in the importance of economic conditions on fertility. Through the 1980s econometric studies had found at best a mixed, neutral or negative effect of economic conditions on fertility. Notably, Butz and Ward (1979) concluded that fertility was counter-cyclical, with fertility falling in good times, as the opportunity costs of ch...
امروزه موضوع اخذ مالیلتها آنقدر ساده و مختصر نیست که فقط بعنوان یک منبع درآمد برای دولت مورد توجه قرار گیرد. بلکه درحال حاضر مالیات بعنوان یکی از وسائل اجرای سیاستهای مالی در جهات مختلف برای نیل به هدفهای گوناگون اقتصادی مورد استفاده قرار میگیرد. از اینها گذشته نمیتوان جنبه اجتماعی و اثرات آن را در تعدیل ثروت انکار کرد و نیز ارتباط مالیاتها را با سایر عوامل اقتصادی مثل درآمد ملی، سرمایه گذاری و...

The effectiveness of conservation organizations is determined in part by how they adapt to changing conditions. Over the previous decade, economic conditions in the United States (US) showed marked variation including a period of rapid growth followed by a major recession. We examine how biodiversity conservation nonprofits in the US responded to these changes through their financial behaviors,...
