A decision maker tests whether the gradient of loss function evaluated at a judgmental is zero. If test does not reject, action decision. rejects, sets equal to boundary rejection region. This statistical rule admissible and conditions on sample realization. The confidence level reflects maker’s aversion uncertainty. applied problem asset allocation.

To what extent can exporters cushion the impact of currency appreciation shocks by using imported intermediates? We apply a partial equilibrium model with heterogeneous firms. Producers can serve the domestic market, export final goods, or import inputs. In the model, an exogenous exchange rate shock simultaneously affects the variable costs and revenues associated with exports and imports. The...

A critical concern for continued growth of the world economy is whether technological progress can mitigate resource depletion. This paper measures depletion effects and technological change for offshore oil production in the Gulf of Mexico using a unique field-level data set from 1947-1998. The study supports the hypothesis that technological progress has mitigated depletion effects over the s...

What factors underlie industry differences in research intensity and productivity growth? We develop a multi-sector endogenous growth model allowing for industry specific parameters in the production functions for output and knowledge, and in consumer preferences. We find that long run industry differences in both productivity growth and R&D intensity mainly reflect differences in "technologica...

The productivity e¤ect of public infrastructure investment is controversial in the traditional literature using aggregate production function estimation, mainly due to reverse causality. This paper develops a new approach, using a model of endogenous productivity in a …rm-level production function, and matching Chinese …rm-level production data with province-level infrastructure data. The estim...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

The purpose of this study is to identify areas energy-efficient development in petrochemical supply chains through the use computer analysis tools. uses system approach methods, comparisons, vertical dynamic analysis, economic and mathematical modeling, forecasting, factor analysis. Listed implementation methods helps meet number scientific results: systematized programs are applicable for prod...

This paper provides parametric estimates of technical change, e¢ ciency change, economies of scale, and total factor productivity growth for large banks (those with assets in excess of $1 billion) in the United States, over the period from 2000 to 2005. In doing so, we propose a distance function based primal total factor productivity growth index, which is valid under both perfect and imperfec...

We examine inventory adjustment in the U.S. manufacturing sector using quarterly rmlevel data over the period 1978{97. Our evidence indicates that the inventory investment process is nonlinear and asymmetric, results consistent with a nonconvex adjustment cost structure. The inventory adjustment process di ers over the business cycle: for a given level of excess inventories, rms disinvest more ...
