To finance unemployment insurance, states raise payroll tax rates on employers who engage in layoffs. Tax are, therefore, highest for firms after downturns, potentially hampering labor-market recovery. Using full-population, administrative records from Florida, I estimate the effect of these increases firm behavior leveraging a regression kink design schedule. hikes reduce hiring and employment...

To what degree can labor reallocation mitigate the economic consequences of weather-driven agricultural productivity shocks? I estimate that temperature-driven reductions in demand for India are associated with increases nonagricultural employment. This suggests ability sectors to absorb workers may play a key role attenuating shocks. Exploiting firm-level variation propensity workers, relative...

This paper proposes a new test of the Protection for Sale (PFS) model by Grossman and Helpman (1994). Unlike existing methods in the literature, our approach does not require any data on political organizations. We use quantile and quantile IV regressions to do so using the data from Gawande and Bandyopadhyay (2000). Surprisingly, the results do not provide any evidence favoring the PFS model. ...

[1] Precipitating particle data from the DMSP F12 and F13 satellites has been merged with image data from the Ultraviolet Imager (UVI) on the Polar satellite. UVI images were combined within single transpolar passes of the DMSP F12 and F13 satellites. Pixel irradiances were then averaged into 1 1 bins along the satellite tracks, thus generating along-track irradiance profiles. Similarly, energy...

Plasma probe data from DMSP-F13, DMSP-F15 and DEMETER satellites were used to examine longitudinal structures in the topside equatorial ionosphere during fall equinox conditions of 2004 year. Since the launch of DEMETER satellite on 29 June 2004, all these satellites operate close together in the topside ionosphere. Here, data taken from Special Sensor-Ion, Electron and Scintillations (SSIES) i...

To quantify trade frictions, we examine multiproduct exporters. We build a flexible general-equilibrium model and estimate market entry costs using Brazilian firm-product-destination data under rich demand access cost shocks. Our estimates show that additional products farther from firm’s core competency come at higher production costs, but there are substantive economies of scope in costs. Mar...

This paper measures excess labor supply in equilibrium. We induce hiring shocks—which employ 24 percent of the force external month-long jobs—in Indian local markets. In peak months, wages increase instantaneously and aggregate employment declines. lean consistent with severe rationing, are unchanged, positive spillovers on remaining workers, indicating that over a quarter is rationed. At least...

This article investigates the problem of optimal tracking control for cyber-physical systems (CPSs) when cyber realm is attacked by Denial-of-Service (DoS) attacks which can prevent signal transmitting to actuator. Attention focused on how design scheme without using system dynamics and analyze impact DoS performance. First, a Riccati equation augmented system, including model reference derived...

Together with a sense of entering a New Economy, the US experienced in the second half of the 1990s an economic expansion, a stock market boom, a financing boom for new firms and productivity gains. In this paper, we propose an interpretation of these events within a general equilibrium model with financial frictions and decreasing returns to scale in production. We show that the mere prospect ...
