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 ...

In view of the extensive evidence of tight inter-relationships between spheroidal galaxies (and galactic bulges) with massive black holes hosted at their centers, a consistent model must deal jointly with the evolution of the two components. We describe one such model, which successfully accounts for the local luminosity function of spheroidal galaxies, for their photometric and chemical proper...

By means of so-called virtual or shadow prices, short-run factor demands, short-run marginal costs, etc. can be derived from any long-run cost function. The traditional approach (short-run/restricted/conditional/variable cost functions) is criticized, and it is also shown that technological change, scale e!ects, etc. can be added to any cost function by means of disembodied factor-augmenting e$...

What factors underlie industry differences in research intensity and productivity growth? We develop a multisector growth model using standard parameters to capture the main factors considered in the empirical R&D and productivity growth literature. Along the balanced growth path, we find that the primary factor behind industry differences in productivity growth is the extent to which new knowl...

Static neoclassical framework cannot be applied to model time dependent processes or increasing returns to scale in production. The dynamization of the neoclassical theory of a firm by dynamic optimization, on the other hand, assumes inconsistent profit functions with the former. As a solution to these problems, we present a dynamic theory of a firm consistent with the static neoclassical theor...
