OBJECTIVES The aim of this study was to determine if the actions of progesterone on preterm labor are accomplished through modulation of the percentage of regulatory T-cells (Treg). METHODS The study was a cohort pilot study made in a single center tertiary obstetrical unit with women in preterm labor arrested with tocolytic treatment. Variation of the number and percentage of Treg cells obta...

This paper is about the explanation of the Great Depression given in Keynes’ General Theory. There are two key ideas in this book that set it apart from pre-Keynesian economics: The first is that there is something distinctive about the labor market that makes the marginal disutility of labor different in general from the real wage. The second is that aggregate economic activity is determined b...

We investigate the effects of interregional labor market integration on the dynamic interaction between migration and capital formation through changes in house prices. The nature of this interaction depends on initial conditions at the time of labor market integration. In an initially capital-poor economy, there may be a reversal of migration during the transition to the steady state, like obs...

Eastern enlargement of the EU promises gains, but also imposes fiscal costs on incumbent countries. A sensitive issue concerns immigration, jobs and wages. We address these issues in a general equilibrium framework, both analytically and through numerical simulations. Analytical results identify capital accumulation as a prime transmission channel. Using a dynamic CGE model with search unemploy...

Analysis of the effects COVID-19 virus on Import, export and labor in Iran using system dynamic approach

An intricate dynamic pattern has been commonly observed in many developed countries during the past decades. This pattern contains a simultaneous rise in the following economic variables: (i) education premium, (ii) educated labor supply, (iii) total factor productivity, (iv) labor productivity, and (v) income inequality. Typical explanations for the different elements of this pattern assume a ...

This paper solves a dynamic model of households’mortgage decisions incorporating labor income, house price, in‡ation, and interest rate risk. It uses a zero-pro…t condition for mortgage lenders to solve for equilibrium mortgage rates given borrower characteristics and optimal decisions. The model quanti…es the e¤ects of adjustable vs. …xed mortgage rates, loan-to-value ratios, and mortgage a¤or...

We solve and estimate a dynamic model that allows agents to optimally choose their labor hours and consumption and that allows for both human capital accumulation and savings. Estimation results and simulation exercises indicate that the intertemporal elasticity of substitution is much higher than the conventional estimates and the downward bias comes from the omission of the human capital accu...

Several frictions restrict the government’s ability to tax assets. First of all, it is very costly to monitor trades on international asset markets. Moreover, agents can resort to non-observable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high. This paper shows that limitations in asset observability have important consequences for the tax...

We specify a dynamic programming model that addresses the interplay among health, financial resources, and the labor market behavior of men late in their working lives. We model health as a latent variable, for which self reported disability status is an indicator, and allow self-reported disability to be endogenous to labor market behavior. We use panel data from the Health and Retirement Stud...
