We study systematically the effect of spatial disorder of ferroelectric domains in nonlinear media on the polarization properties of optical frequency conversion. Experimentally, different statistics of domain sizes are created using electric field poling at room temperature. We analyze the evolution of polarization properties of the second- and third-harmonic signals for each created statistic...

There is strong evidence that exporting firms are better. This correlation can potentially arise from many alternative casual models. In this paper, we utilise the natural experiments offered by transitioning into export in a dataset of Indian firms from 1990 to 2011, where each firm which made the transition is matched against one which did not. While exporting firms become bigger, there is no...

We measure the capacity output of a firm as the maximum amount producible by a firm given a specific quantity of the quasi-fixed input and an overall expenditure constraint for its choice of variable inputs. We compute this indirect capacity utilization measure for the total manufacturing sector in the US as well as for a number of disaggregated industries, for the period 1970-2001. We find con...

− A theoretical framework is developed for decomposing partial factor productivity and measuring technical inefficiency when the underlying technology is characterized by factor non-substitution. With Farrell’s (1957) radial index of technical inefficiency being inappropriate in this case, Russell’s (1985; 1987) non-radial indices are adapted to measure technical inefficiency in a Leontief mode...

In this paper the time series properties of the outcomes of two different specifications of a nonparametric productivity analysis are compared using data for threeand four-digit U.S. manufacturing industries over the period 1958-96. The first model is standard and does not account for variations of capacity utilization of the production factors whereas the second model does. Correcting for util...

This study explores the reduction potential of greenhouse gases for major pollution emitting countries of the world using nonparametric productivity measurement methods and directional distance functions. In contrast to the existing literature we apply optimization methods to endogenously determine optimal directions for the efficiency analysis. These directions represent the compromise of outp...

This paper examines the impact of floods on firms’ capital accumulation, employment growth and productivity by using a difference-indifference approach and considering firms’ asset structure. We find evidence that after a flooding companies in flooded regions show on average higher growth of total assets and employment than firms in areas not affected by flooding. The positive effect prevails f...

This paper employs a matched firm production-innovation panel dataset from Chile to explore the response of innovation increased competition arising China shock. The data cover wider range inputs and outputs than previously possible allow generating measures markups efficiency (TFPQ) that correspond closely concepts rents technological leadership envisaged in Schumpeterian literature. Except fo...

We quantify the importance of imperfect competition in US labor market by estimating size rents earned American firms and workers. construct a matched employer-employee panel dataset combining universe business worker tax records for period 2001–2015. Using this data, we identify estimate an equilibrium model with two-sided heterogeneity where workers view as substitutes because heterogeneous p...

abstract research and development (r&d;) spending plays a major role in innovation, raising productivity and increasing economic growth. the purpose of this paper is to investigate the impact of r&d; spending on growth and total factor productivity (tfp) in iran's agricultural sector. we estimate growth and productivity models using auto-regressive distributed lag (ardl) approach and data over ...
