it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...

Labor supply functions for married men and women are formulated as a dynamic simultaneous equations ystem, which is estimated using panel data. Controlling for fixed individual effects allows marginal labor supply responses to be disentangled from permanent patterns in hours worked ue to assortative mating. The results suggest hat the labor supply of husbands and wives without pre-school childr...

The prospect of immigration reform has renewed farmers’ concerns of serious labor shortages and cost increases, which may urge highly labor-intensive specialty crop farmers to switch to less-labor-intensive technology. The large-scale mechanization of the Florida sugarcane harvest during the 1970s/80s serves as an historical example of how technologies evolved due to changes in local labor mark...

Economic growth in Sub-Saharan Africa has been characterized by deindustrialization. Conventional economists argue that this is due to a bad environment for business decision making. This paper provides a classical explanation for deindustrialization, the failure to solve the food problem. That is, food staple prices have risen rapidly resulting in labor becoming costly, although physically abu...

Estimating the Firm’s Labor Supply Curve in a “New Monopsony” Framework: School Teachers in Missouri In the context of certain dynamic models, it is possible to infer the elasticity of labor supply to the firm from the elasticity of the quit rate with respect to the wage. Using this property, we estimate the average labor supply elasticity to public school districts in Missouri. We take advanta...

تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...

In this paper a computationally practical simulation estimator is proposed for the twotiered dynamic panel Tobit model originally developed by Cragg (1971). The log-likelihood function simulated through procedures based on a recursive algorithm formulated by the Geweke-Hajivassiliou-Keane simulator is maximized. The simulation estimators are then applied to study the labor supply of married wom...

BACKGROUND Sufficient information from in vitro and in vivo studies has become available to permit computer modeling of the processes that occur in the myometrium during labor. This development allows the in silico investigation of pathological mechanisms and the trialing of potential treatments. METHODS/RESULTS Based on the human literature, we developed a computer model of the immune-endocr...

This paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labor market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary effects of insurance on the performance of the labor market into consideration. Agents with higher cost of moving, i.e....
