The paper investigates the measurement of economic efficiency under transaction costs in a second best world. New measurements of technical efficiency, allocative efficiency, and price efficiency are proposed. They have three desirable properties. First, they measure efficiency loss in monetary units. Second, they are additive and can be conveniently summed into an overall efficiency measure. Third, they allow for transaction costs and their effects on prices and trade incentives. The paper investigates the welfare effects of technology choice, government pricing and trade policy, and market imperfections on efficiency. It provides new insights on the measurement of benefits from trade liberalization when trade affects not only price efficiency, but also technical and allocative efficiency.

We present and discuss measures for analyzing productivity in deterministic frontier models. A new efficiency measure is introduced
allowing for discrimination among efficient organizational units. In addition, a new performance measure for analyzing productivity of organizational units is presented. This measure fulfills various properties of efficiency measures
but relaxes the indicator property. Both new approaches are based on the development of efficiency vectors which is a new vector measure for measuring efficiency. The vector components are efficiency measures related to subsets
of a production possibility set. The new approaches are applied in the context of data envelopment analysis.

Stochastic productivity indicators are defined, and superlative measures of these indicators are derived. It is shown that,
in the presence of complete markets or a common-expectations equilibrium, differences in the market values of firms are superlative
indicators of cross-sectional productivity differences. Exactness results are used to decompose nonstochastic productivity
indicators into a measure of true productivity change and a measure of ‘luck’. The decomposition is illustrated empirically.

The purpose of this paper is to evaluate the variations in SOE efficiency and productivity from the perspectives of macroeconomic
fluctuations and systematic reform in China during 1986–2003. We use Data Envelopment Analysis to measure SOE efficiency.
Subsequently, we use the Malmquist Index of Productivity change to measure productivity growth. The empirical results show
that SOE efficiency and productivity exhibited obvious improvements during periods of strong systematic reform and a prosperous
economy. The systematic reform after 1998 had a clear-cut impact on SOE performance.

This study measures productivity growth on Irish dairy farms over the period 1984–2000. A total factor productivity index
is constructed for the dairy system and is decomposed into technical change, efficiency change, and changes in scale efficiency.
This is achieved by estimating a stochastic output distance function model of the production technology in use on Irish dairy
farms. Overall, productivity on Irish dairy farms grew by 1.2% per annum over the sample period.

We develop a model of labor productivity as a combination of capital-labour ratio, vintage of capital stock, regional externalities,
and total factor productivity (TFP). The skewness of TFP distribution is related to different growth theories. While negative
skewness is consistent with the neo-Schumpeterian idea of catching up with leaders, zero skewness supports the neoclassical
view that deviations from the frontier reflect only idiosyncratic productivity shocks. We argue that positive skewness is
consistent with an economy where exogenous technology is combined with non-transferable knowledge accumulated in specific
sectors and regions. This argument provides the framework for an empirical model based on stochastic frontier analysis. The
model is used to analyse regional and sectoral inequalities in Denmark.

Decompositions of total factor productivity (TFP) shed light on the driving factors behind productivity change. We develop
the first exact decomposition of the Fisher ideal TFP index which contains no debatable mixed-period components or residuals.
We systematically isolate five effects of (1) technical change, (2) technical efficiency, (3) scale efficiency, (4) allocative
efficiency, and (5) price effect. The three efficiency components (2–4) represent the efficiency of achieving a given target
point. Components (1) and (5) capture the changes of the target point. While the technical change component is well-established,
changes in the relative input–output prices can have real effects on the scale and scope of the target. Such changes are captured
by the new price effect component (5). The new decomposition is compared with existing decompositions both in theory and by
means of an empirical application to a panel data of 459 Finnish farms in years 1992–2000.

Sources of profit change for Telstra, Australia’s largest telecommunications firm, are examined. A new method allows for changes, in a firm’s profits to be broken down into separate effects due to productivity change, price changes, and growth in the firm’s size. This in turn allows us to calculate the distribution of the benefits of productivity improvements between consumers, labor, and shareholders. The results show that around half the benefits from Telstra’s productivity improvements from 1984 to 1994 were passed on to consumers in the form of real price reductions.

The effects of match uncertainty and bargaining on labor market outcomes: evidence from firm and worker specific estimates 总被引:3,自引:0,他引:3
In this paper we examine wage dispersion in labor markets across currently employed workers. We argue that differences in
the potential productivity of a match (typically assumed to be known in the previous literature) generates a surplus between
the minimum wage the worker is willing to accept and the maximum wage the firm is willing to offer for the job. Existence
of this surplus leads to wage dispersion due to negotiating over the amounts extracted by each agent. Our objective is to
estimate the surplus extracted by each firm-worker pair and the effect of the net extracted surplus on the wage, for each
firm-worker pair using the two-tier stochastic frontier model. An empirical application finds that, on average, firms paid
workers less than their expected productivity. More specifically, at the mean, the net effect of productivity uncertainty
leads to equilibrium wages which are 3.33% below the expected productivity of matches.

Many observers argued that Barack Obama’s candidacy in the U.S. presidential election of 2008 benefited from the financial
crisis and recessionary economic conditions which voters blamed on the Republican administration. However, an empirical examination
of stock price and public opinion data indicates that improvements in Obama’s electoral prospects led stock price declines
and that gains by Obama were more likely to be followed by falling stock prices than by rising prices. This evidence suggests
that the poor performance of the stock market in the days leading up to Obama’s victory was partly caused by, rather than
causing, Obama’s success.

The paper contributes to the explanation of the large differences in cross-country productivity performance by modelling and
testing the effects of social barriers to communication on productivity and capital accumulation. In an optimal growth model,
social barriers to communication, which impede the formation of knowledge connections, are shown to reduce both transitory
and steady-state levels of total factor productivity (TFP), per capita consumption and reproducible capital. Empirical testing
yields a robust and theoretically consistent result: linguistic barriers to communication reduce productivity and capital
accumulation. The findings provide an explanation for cross-country differences in TFP, and fresh insights into how productivity
‘catch up’ may be initiated.

Debreu’s coefficient of resource utilization is freed from individual data requirements. The procedure is shown to be equivalent
to the imposition of Leontief preferences. The rate of growth of the modified Debreu coefficient and the Solow residual are
shown to add up to TFP growth. This decomposition is the neoclassical counterpart to the frontier analytic decomposition of
productivity growth into technical change and efficiency change. The terms can now be broken down by sector as well as by
factor input.

This paper examines the impact of R&D on multifactor productivity in the U.S. agricultural sector over the 1910–1990 period.
We use the Bennet–Bowley indicator to measure agricultural productivity based on a multiple output-multiple input technology.
We demonstrate the relationship between the price dependent Bennet–Bowley indicator and the Luenberger productivity indicator
which is constructed from directional distance functions without requiring price information. These performance measures are
dual to the profit function which arguably makes them especially useful in the agricultural setting. We employ time-series
techniques to investigate the effect of R&D on the pattern of productivity growth. We find that we cannot reject the presence
of a cointegrating relationship between the two series and that productivity growth in the U.S. agriculture responds positively
to R&D expenditure with a lag of between four and ten periods.

This paper aims to assess if geographic proximity from universities enhances small firms’ performance, by means of knowledge
spillovers. A sample of micro data is used on 390 manufacturing firms and 11 public universities in Portugal. Performance
is measured by labour productivity. The estimation was made using OLS as well as Quantile Regression. Results seem to confirm
that both domains of knowledge do produce distinct effects, but there is no evidence that a firm’s performance improves with
the proximity to a university. Likewise, the quality of universities does not seem to influence the labour productivity of
firms.

This paper considers the measurement of performance in public service provision in an international context by examining outcome-based
measures for the education sector. It first sets out the measurement issues in general terms. The paper then applies these
methods to comparing the UK experience with that in the US over the period 1979–2002. The results show higher labour productivity
growth in the UK education sector than in the US over this time period, so that the UK eliminated the productivity gap with
the US by the end of the Century.

Several studies in the literature have tried to assess the impact of real depreciation of the Canadian dollar on the Canadian
trade balance. They have either relied on the trade data between Canada and the rest of the world or between Canada and her
major trading partners. In this paper we consider the trade between Canada and her major trading partner, the U.S. However,
unlike previous research, we disaggregate the trade data between the two countries by commodity. We use export and import
data over the period 1962–2004 from 152 commodities and the bounds testing approach to cointegration and error-correction
modeling and show that real depreciation of the Canadian dollar has short-run effects on the trade balance of two-thirds of
the industries. However, only in 50% of the industries, the short-run effects translate into the long-run favorable effects.

This paper examines the relationship between multinationality and firm performance. The analysis is based on a sample of over
400 UK multinationals, and encompasses both service sector and manufacturing sector multinationals. This paper confirms the
non-linear relationship between performance and multinationality that is reported elsewhere in the literature, but offers
further analysis of this relationship. Specifically, by correcting for endogeneity in the investment decision, and for shocks
in productivity across countries, the paper demonstrates that the returns to multinationality are greater than those that
have been reported elsewhere, and persist to higher degrees of international diversification.

This study analyzes the impact of trade on wages in the context of the specific factors model by focusing on the link between
trade and the average real wage. A recent paper by Jones and Ruffin (Rev Int Econ, 16:234–249, 2008) shows how one can use
the specific factors model to predict how labor should fare from an improvement in the terms of trade. For this purpose, I
use annual firm-level data on the manufacturing sector in Ghana during the period 1991–1997. I find that a ceteris paribus increase in the price of exportables in the wood industry would help labor but labor would be hurt by price increases in
the food-baker, furniture, textile-garment, and metal-machinery industries.

Determining the profit maximizing input–output bundle of a firm requires data on prices. This paper shows how endogenously
determined shadow prices can be used in place of actual prices to obtain the optimal input–output bundle where the firm’s
shadow profit is maximized. This approach amounts to an application of the Weak Axiom of Profit Maximization (WAPM) formulated
by Varian [(1984) The Non-parametric approach to production analysis. Econometrica 52:3 (May) 579–597] based on shadow prices rather than actual
prices. At these shadow prices, the shadow profit of a firm is zero. The maximum shadow profit that could have been attained
at some other input–output bundle is shown to be a measure of the inefficiency of the firm. Because the benchmark input–output
bundle is always an observed bundle from the data, it can be determined without having to solve any elaborate programming
problem.

How clusters can encourage entrepreneurship and venture creation. Reasons and advantages 总被引:3,自引:0,他引:3
Ana María Romero-Martínez Ángeles Montoro-Sánchez 《The International Entrepreneurship and Management Journal》2008,4(3):315-329
The aim of this article is to define what is meant by clusters, their characteristics or determinants and the advantages they
generate, focusing on the role they play in boosting entrepreneurship and new venture creation. In clusters, a balance is
reached between cooperation and competition which becomes evident in the higher productivity of the companies because of their
increased access to inputs, information, technology and institutions; or in greater innovation and venture creation. The cluster
incentivizes the entry of new companies or start-ups. The hope is, then, that the new companies will revitalize specific regions
where competitiveness has fallen and that entrepreneurship will contribute to economic development and improved country-wide
competitiveness.
