Property Rights, Labour Markets, and Efficiency in a Transition Economy: The Case of Rural China

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China during transition. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of land, and the extent of unevenly developed non-agricultural opportunities. Using a recently collected household survey, we show that a considerable amount of inefficiency exists in the countryside, especially in the employment of labour. Our results show that this inefficiency is alleviated by the development of external labour markets, and that in the context of the current imperfect market environment, administrative reallocations help improve on the margin both efficiency and equity. They do not go far enough, however, which raises important questions about constraints on rental activity, the link between admin istrative reallocation and decentralized land exchange, and property rights formation more generally.http://deepblue.lib.umich.edu/bitstream/2027.42/39903/3/wp518.pd

An Empirical Model of Growth Through Product Innovation

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a modified version of the Schumpeterian theory of firm evolution and growth developed by Klette and Kortum (2004). The data set is a panel of Danish firms than includes information on value added, employment, and wages. The model's fit is good and the structural parameter estimates have interesting implications for the aggregate growth rate and the contribution of worker reallocation to it.labor productivity growth; worker reallocation; firm dynamics; firm panel data estimation

Graphical modelling language for spycifying concurrency based on CSP

Introduced in this (shortened) paper is a graphical modelling language for specifying concurrency in software designs. The language notations are derived from CSP and the resulting designs form CSP diagrams. The notations reflect both data-flow and control-flow aspects of concurrent software architectures. These designs can automatically be described by CSP algebraic expressions that can be used for formal analysis. The designer does not have to be aware of the underlying mathematics. The techniques and rules presented provide guidance to the development of concurrent software architectures. One can detect and reason about compositional conflicts (errors in design), potential deadlocks (errors at run-time), and priority inversion problems (performance burden) at a high level of abstraction. The CSP diagram collaborates with objectoriented modelling languages and structured methods

Exchange Rate, Employment and Hours: What Firm-Level Data Say

Using a representative panel of manufacturing firms, we estimate the response of job and hours worked to currency swings, showing that it depends primarily on the firm's exposure to foreign sales and its reliance on imported inputs. Further, we show that, for given international orientation, the response to exchange rate fluctuations is magnified when firms exhibit a lower monopoly power and when they face foreign pressure in the domestic market through import penetration. The degree of substitutability between imported and other inputs and the distribution of workers by type introduce additional degrees of specificity in the employment sensitivity to exchange rate swings. Further, wage adjustments are also shown to provide a channel through which firms react to currency shocks. Finally, gross job flows within the firm are found to depend on exchange rate fluctuations, although the effect on job creation is predominant.Employment, Exchange Rate, Firm's Foreign Exposure

Property Rights, Labor Markets, and Efficiency in a Transition Economy: The Case of Rural China

This paper investigates the consequences of imperfect and uneven factor market development for farm efficiency in rural China. In particular, we estimate the extent to which an inverse relationship in farm productivity can be attributed to the administrative (instead of market) allocation of land, and the extent of unevenly developed non-agricultural opportunities. Using a recently collected household survey, we show that a considerable amount of inefficiency exists in the countryside, especially in the employment of labor. Our results show that this inefficiency is alleviated by the development of external labor markets, but perhaps more surprisingly, that in the context of the current imperfect market environment, administrative reallocations help improve both efficiency and equity on the margin. They do not go far enough, however, which raises important questions about constraints on rental activity and the link between administrative reallocation and decentralized land exchange.

Why is productivity procyclical? Why do we care?

Productivity rises in booms and falls in recessions. There are four main explanations for this procyclical productivity: (i) procyclical technology shocks, (ii) widespread imperfect competition and increasing returns, (iii) variable utilization of inputs over the cycle, and (iv) resource reallocations. Recent macroeconomic literature views this stylized fact of procyclical productivity as an essential feature of business cycles because each explanation has important implications for macroeconomic modeling. In this paper, we discuss empirical methods for assessing the importance of these four explanations. We provide microfoundations for our preferred approach of estimating an explicitly first-order approximation to the production function, using a theoretically motivated proxy for utilization. When we implement this approach, we find that variable utilization and resource reallocations are particularly important in explaining procyclical productivity. We also argue that the reallocation effects that we identify are not "biases" -- they reflect changes in an economy’s ability to produce goods and services for final consumption from given primary inputs of capital and labor. Thus, from a normative viewpoint, reallocations are significant for welfare; from a positive viewpoint, they constitute potentially important amplification and propagation mechanisms for macroeconomic modeling.Productivity ; Business cycles

The Link Between Aggregate and Micro Productivity Growth: Evidence from Retail Trade

Understanding the nature and magnitude of resource reallocation, particularly as it relates to productivity growth, is important both because it affects how we model and interpret aggregate productivity dynamics, and also because market structure and institutions may affect the reallocation's magnitude and efficiency. Most evidence to date on the connection between reallocation and productivity dynamics for the U.S. and other countries comes from a single industry: manufacturing. Building upon a unique establishment-level data set of U.S. retail trade businesses, we provide some of the first evidence on the connection between reallocation and productivity dynamics in a non-manufacturing sector. Retail trade is a particularly appropriate subject for such a study since this large industry lies at the heart of many recent technological advances, such as E-commerce and advanced inventory controls. Our results show that virtually all of the productivity growth in the U.S. retail trade sector over the 1990s is accounted for by more productive entering establishments displacing much less productive exiting establishments. Interestingly, much of the between-establishment reallocation is a within, rather than between-firm phenomenon.
