This paper explores the effects of capital controls and policies regulating interest rates and the exchange rate in a model of economic transition applied to China. It builds on Song, Storesletten, and Zilibotti (2011) who construct a growth model consistent with salient features of the recent Chinese growth experience: high output growth, sustained returns on capital investment, extensive real...

A standard assumption in integrated assessment models of climate change is that population and productivity are growing, but at a decreasing rate. We explore the signi cance of the assumption of population and productivity growth for greenhouse gas abatement. After all, there has been no long run slow down in the growth of productivity over the past few centuries, and the rate of population gro...

Shimer (2005) argues that a search and matching model of the labor market in which wage is determined by Nash bargaining cannot generate the observed volatility in unemployment and vacancy in response to reasonable labor productivity shocks. This paper examines how incorporating monopolistically competitive firms with a working capital requirement (in which firms borrow funds to pay their wage ...

The historical context surrounding the birth of the DARPA High Productivity Computing Systems (HPCS) program is important for understanding why federal government agencies launched this new, longterm high performance computing program and renewed their commitment to leadership computing in support of national security, large science, and space requirements at the start of the 21st century. In t...

Manufacturing process frequently employs optimization of machining parameters in order to improve product quality as well as to enhance productivity. The material removal rate is a significant indicator of the productivity and cost efficiency of the process. Taguchi method has been implemented for assessing favorable (optimal) machining condition during the machining of nylon by considering thr...

In vivo chlorophyll fluorescence associated to Photosystem II is being used to evaluate photosynthetic activity of microalgae grown in different types of photobioreactors; however, controversy on methodology is usual. Several recommendations on the use of chlorophyll fluorescence to estimate electron transport rate and productivity of microalgae grown in thin-layer cascade cultivators and metha...

BACKGROUND This study aimed to measure the hospital productivity using data envelopment analysis (DEA) technique and Malmquist indices. METHODS This is a cross sectional study in which the panel data were used in a 4 year period from 2007 to 2010. The research was implemented in 12 teaching and non-teaching hospitals of Ahvaz County. Data envelopment analysis technique and the Malmquist indic...

This study experimentally demonstrated a feed-forward inversion control scheme for maintaining an optimum incident irradiance on photobioreactors (PBRs) during batch cultivation. A data-based modelfree optimization using quadratic fit was utilized to rapidly estimate the optimum average fluence rate set point value that rendered maximum microalgae growth rate. Then, the feed-forward inversion c...

We examine the efficiency of conservation of a renewable resource whose natural productivity is influenced by random environmental disturbances. We allow for non-concave biological production and stock-dependent social welfare. Unlike deterministic models, conservation may be inefficient no matter how productive the resource growth function is. In addition, improvements in the natural productiv...

Innovation is a source of increasing productivity, but it is also a source of stress. Psychological research shows that moderate stress increases the productivity of an actor, but above a certain level, additional stress decreases productivity. Stress is reduced by coping behaviour of the actor, and in addition it is buffered by social relations. However, high levels of stress negatively affect...
