We incorporate forward?looking capital accumulation into a dynamic discrete choice model of migration. characterize the steady?state equilibrium; generalize existing exact?hat algebra techniques to investment; and linearize provide an analytical characterization economy's transition path using spectral analysis. show that labor dynamics interact shape speed adjustment toward steady state. imple...

An emerging labor economics literature studies the consequences of firms exercising market power in local markets. These monopsony models have implications for trends earnings inequality. The extent this is likely to vary across In choosing what live and work in, workers trade off wages, rents amenities. Building on Rosen/Roback spatial equilibrium model, we investigate how existence affects cr...

spatial-temporal modeling of air pollutants, ground-level ozone concentrations in particular, has attracted recent attention because by using spatial-temporal modeling, can analyze, interpolate or predict ozone levels at any location. in this paper we consider daily averages of troposphere ozone over tehran city. for eliminating the trend of data, a dynamic linear model is used, then some featu...

This paper presents a conceptual modeling study on the behaviors of terrestrial biosphere–atmosphere systems as they relate to multiple equilibrium states and climate variability, and emphasizes their implications for physically based climate modeling. The conceptual biosphere–atmosphere model consists of equilibrium responses of vegetation and precipitation to each other, dynamics of the veget...
