Journal: :The American Economic Review 2022

We document that nearly half of the global decline in agricultural employment was driven by new cohorts entering labor market. A dataset policy reforms supports an interpretation these cohort effects as human capital. Using a model frictional reallocation, we conclude capital growth led to sharp supply, accounting, at fixed prices, for 40 percent decrease employment. This aggregate effect is ha...

Our research aims to determine the effect of electricity distribution and energy consumption on industrial development dynamics that occur between regions in Indonesia by adding investment inflation as control variables. The analysis tools we use are static (Fixed Effect) dynamic (GMM) panel data model with a dataset 34 provinces for 2012-2019 period. results state has significant positive indu...

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...

Enterobacteriaceae share a common antigen (CA). This antigen exists as a powerful immunogen, when produced by Escherichia coli O14, and as a minimally effective immunogen, when present in cultures of most other smooth strains. The present study was directed toward the assessment of immunogenicity of this antigen produced by various rough mutants and their parent strains as well as that of viabl...

α-amylase has been studied extensively from various sides. this enzyme is used in many industries .many applications of this enzyme have encouraged us for greater attempts on the study of α-amylase and to search for more effective processes. in this investigation, the structure of nanotube - catalytic site of bacillus subtilis α- amylase was optimized by hyperchem 7.0 and then it was investigat...

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...

While privatization of state-owned enterprises (SOEs) remains a popular policy tool in many countries, the impacts on workers are unclear. This paper studies case Brazil, which implemented large program 1990s. Following privatization, incumbent privatized SOEs suffer wage decline roughly 25 percent relative to matched control group. Additionally, private sector firms that connected by labor mob...
