Trade, Skills and Adjustment Costs: A Study of Intra-Sectoral Labor Mobility

The relationship between the ability of workers to change job, sector or industry and the short‐run adjustment costs associated with a reallocation of labor is the subject of lively debate among academics. This paper examines recent sector and industry level labor market adjustment in the UK using data from the Quarterly Labour Force Survey. We explore the link between the nature of UK trade patterns and labor adjustment within the manufacturing sector and employ a multinomial logit approach to examine the determinants of “within” and “between” industry mobility. By controlling for individual skill specificity we find some evidence of a link between intra‐industry trade and intra‐industry labor adjustment.     

ECONOMIC PRODUCTIVITY IN ISRAEL, 1950–1965 1

Macroeconomic productivity in Israel is here conceived as comparison of output with factor inputs during given periods, and as creation of sustained capacity out of given resource increments. However, present social accounting practice prevents full implementation of this second approach. In contrast to nine European countries, only one third of the rapid growth rate of Israel in 1950–1965 is “explained” by the “Residual” because of relatively large infrastructural investments and of growth problems. One of these problems is inflationary pressures which caused productivity increases to restrain the rise of product prices by 30 per cent only below the rise of input prices. The real productivity gain accrued, in Israel and in the U.S.A. (1919–1957), nearly fully to labor because unit returns to capital remained constant whereas those to labor sharply rose. Some refinements of the statistical models are attempted by incorporating the utilization rates of labor and capital (for industry); and by measuring product from the uses, instead of from the income, side, adding the differences to the capital shares. This makes distributive factor shares nearly constant as postulated by Cobb-Douglas. In order to get a basis for appraising efficiency in creating long-term capacity, that part of product increments is measured which represents rises of p.c. final domestic uses and changes in the export surplus. This “net margin” formed in Israel one fifth and in the U.S.A. (1889–1913) much less of incremental product. Though in Israel one quarter, and in the U.S.A. over half (in 1919–1953) of the net margin went into sonsumption, large proportions of it presumably actually created human capacity. A comparison of product growth rates with population growth, and of the breakdown of the resulting p.c. product growth rates into full final uses, for Israel and two groups, of developed and less developed countries in the fifties shows, inter-alia, that in the L.D.C. only small proportions of their presumable capacity creation was financed by net capital inflows, thus imposing upon them domestic saving rates which presumably are too high to be sustainable.     

Striking a balance: Optimal tax policy with labor market duality

We develop a dynamic general equilibrium model where employers may avoid making social security contributions by offering some workers “secondary contracts.” When calibrated using aggregate tax revenue data, the model delivers estimates of secondary “off the books” employment that are consistent with survey evidence for the EU14 and United States. We investigate the fiscal and welfare effects of varying the avoidable and unavoidable shares of labor income tax while keeping the total wedge constant, and find that increasing the employer component raises hours worked, output, and welfare. Partial labor tax evasion makes tax revenues more elastic, but full tax compliance need not be a welfare enhancing policy mix.     

GROWTH AND WELFARE EFFECTS OF WORLD MIGRATION

Using a two‐bloc endogenous growth model calibrated to two generic sending and receiving countries of equal size, we assess the growth and welfare impact of world migration flows of different skill compositions. The sending country (East) has a lower total factor productivity and a lower endowment of skilled labour. Migration can induce two growth‐enhancing effects: an efficiency effect from the more efficient use of labour in the receiving country (West) and a sectoral reallocation effect from a fall in the host country skilled–unskilled wage rates. Despite growth gains, there are both winners (migrants, the representative Western non‐migrant household) and losers (the representative Eastern household remaining). Remittances can see the latter group joining the winners.     

A bias in growth-rate comparisons of capitalist and socialist economies

An economy is described by an n-sector linear production matrix and a fixed vector of consumption needs. There are many ways in which goods may be priced and many ways in which “surplus labor” may be allocated among sectors. Depending on which vector of prices and which distribution of surplus labor prevails, the average growth rate of the economy will differ. It is shown that the surplus-labor-price constellation likely to prevail in oligopolistic, free-enterprise economies overestimates the “true” growth rate, and in a centrally planned socialist economy underestimates it. This raises the question whether actual growth rates are systematically biased in the directions indicated. J. Comp. Econ.,     

Examining crop price effects on production decision and resource allocation: an ex-ante approach

This article examines the output price effects on the US crop production, employing an ex-ante approach to the differential systems of input demand and output supply. The estimation results of the differential input demand show that the expansion of crop production leads to an increase in acreage (i.e. extensive margin) and a proportional rise in input usage improving yield per acre (i.e. intensive margin). The substitutable relationship between fertilizer and land supports that crop producers have an option to choose either intensive or extensive margin in response to changes in their relative prices. In addition, the estimation results of the differential output supply highlight that the composition of crop supply can be altered by changes in ex-ante crop prices. The estimation results suggest that crop producers substitute corn supply for the supply of cotton, wheat and soybeans or vice versa. Based on the estimated elasticities, the decompositions of profit-maximizing input demand are conducted, which reveals that a change in ex-ante crop prices is associated closely with resource reallocation.     

Crossing Hubbert’s peak: Portfolio effects in a growth model with exhaustible resources

This paper elaborates a two-class growth model with an exhaustible resource (“oil”) and an alternative technique (“solar”). Bequest savers accumulate wealth, consisting of capital and oil, saving a constant fraction of their end-of-period wealth. The price of oil obeys Hotelling’s rule. Rising oil prices and the depletion of oil supplies create portfolio effects on the accumulation of capital. When growth is constrained by an exogenously increasing labor force, these wealth effects express themselves in changes in the distribution of income, which first shifts toward profits and then shifts back toward wages as the oil stocks approach depletion. When growth is constrained by capital (the labor force is endogenous), the portfolio effects express themselves in changes in the rate of capital accumulation, which first declines and then rises sharply as the oil stocks approach depletion.     

COMPTABILITE NATIONALE A PRIX CONSTANTS ET A PRODUCTIVITE CONSTANTE

The problem of national accounting “at constant prices” is in fact a problem of comparability of time series, as changes in the price structure preclude any direct comparison of economic flows. If such accounts are established they will make it possible directly to compare the same flow at two different times in the economy as a whole, and this without leaving the influence of other flows out of account. This makes it possible both to synthesize and to undertake analytical comparisons. The accounts could then be used for the study of time series, for projections or for structural studies (e.g. the mechanisms underlying the changing pattern of income distrubution). The first part of this report sets out to study the main problems of compiling accounts at constant prices and to examine what conventions should be adopted. The second part of the report considers how productivity gains can be explicitly shown in the national accounts. The proposed study plan restores the symmetry between price and productivity. As in the accounts at constant prices, gap variables are introduced to measure productivity gains. These variables can be interpreted in terms of surplus; the concept of surplus used here, however, is not the one adopted for the accounts in constant prices, but its dual. Setting up an accounting system “at constant productivity” therefore makes it possible to complete the information provided by an accounting system “at constant prices.” These two systems can of course be integrated: this leads to the introduction of the concept of an accounting system “at constant prices and constant productivity.” Such an accounting system makes it possible to show, in the same accounting framework, the respective contributions of price changes and improved productivity to the gains realised by the different economic agents. It therefore gives a complete picture of “transfers” between the agents. At the same time, the data on price and productivity can be integrated with each other.     

Carbon Abatement and International Spillovers

Carbon abatement policies in large open economies affect both the allocation of domestic resources and international market prices. A change in international prices implies an indirect secondary burden or benefit for all trading countries. Based on simulations with a large-scale computable general equilibrium model of global trade and energy use, we show that international spillovers have important welfare implications for carbon abatement policies designed to meet exogenous emission reduction targets. We present a decomposition of the total welfare effect of carbon abatement policies into a primary domestic market effect (at constant international prices) and a secondary international spillover impact as a result of changes in international prices. This decomposition reveals the extent to which domestic abatement costs are increased or decreased as a result of the impact of carbon abatement on international prices.     

European influence and economic development

The development accounting literature identifies political institutions as fundamental development determinants. Forms of government or executive constraints are thought to shape economic institutions (e.g., property rights) that provide necessary incentives for economic growth. One strand of the literature suggests that European influence is a crucial economic development determinant, presumably through the adoption of European institutions. But how exactly did European influence in the distant past induce positive economic outcomes today? Previous approaches rely on “language,” “settler mortality,” “legal origins” or the “number of European settlers” as indirect proxies of European influence. We propose a direct and quantifiable mechanism: the adoption of European constitutional features. We construct a dataset of all constitutional dimensions from 1800–2008 for all countries and find that nations experience growth accelerations after adopting features of European constitutions. The growth effects are influenced (negatively) by periods of political turmoil, but they are independent of colonial backgrounds. These results show how European influence may have fostered growth, and they imply that countries were able to overcome adverse initial conditions over the last 200 years by adopting European constitutional features. Our constitutional dataset is sufficiently detailed to identify the specific dimensions of European constitutions that matter most for development: legislative rules and specific provisions that curtail executive powers.     

Overcoming coordination failure using a mechanism based on gradualism and endogeneity

We examine three tools that can enhance coordination success in a repeated multiple-choice coordination game. Gradualism means that the game starts as an easy coordination problem and moves gradually to a more difficult one. The Endogenous Ascending mechanism implies that a gradual increase in the upper bound of coordination occurs only if coordination with the Pareto superior equilibrium in a stage game is attained. The Endogenous Descending mechanism requires that when the game’s participants fail to coordinate, the level of the next coordination game be adjusted such that the game becomes simpler. We show that gradualism may not always work, but in such instances, its effect can be reinforced by endogeneity. Our laboratory experiment provides evidence that a mechanism that combines three tools, herein termed the “Gradualism with Endogenous Ascending and Descending (GEAD)” mechanism, works well. We discuss how the GEAD mechanism can be applied to real-life situations that suffer from coordination failure.     

The creative class, its preferences, and unbalanced growth in an urban economy

We theoretically analyze unbalanced growth in an urban economy arising from the preferences of the creative class concerning the relative desirability of agricultural, manufacturing, and service goods. We study two cases. In the first case, the production functions for the three categories of goods are identical. Our analysis leads to four results. First, we compute the equilibrium physical to creative capital ratios and the relationships between the neutral productivity shifters and the output prices. Second, we show that agricultural and services consumption are a constant multiple of manufacturing consumption. Third, we note that under certain conditions, an equilibrium in which all sectors of our urban economy grow at a constant rate does not exist. Fourth, we show that a constant growth path (CGP) equilibrium exists in which, across the three sectors, the pattern of consumption changes and there is a reallocation of creative capital. In the second case, the production functions for the three categories of goods are dissimilar. In this more realistic setting, we study generalizations of the previously described four results.     

Asymmetries in price and quantity adjustments by the competitive firm

Focusing on the crucial role of inventory carry-overs in the production and sales decision, we describe the profit maximizing behavior of a dynamic competitive firm facing random prices. Each firm's behavior is incorporated into a stochastic equilibrium model of the competitive industry with uncertain demand. The industry model exhibits asymmetric cyclical fluctuations of the “Keynesian” sort: when demand is weak, output contracts while price holds at a fixed floor; when demand is strong, price increases as output is constrained by a ceiling. Even in a pure world of constant returns, without increasing costs, the inability to instantaneously coordinate production and sales along with the existence of inventories is sufficient to yield a “backward L” shaped supply curve for the short run.     

Adjusting the measurement of US manufacturing productivity for air pollution emissions control

We estimate a distance function and derive producer shadow prices for SO₂ and PM-10 emissions. The shadow prices are used to adjust a traditional measure of total factor productivity growth in order to account for the reallocation of inputs from production of the marketed output to pollution abatement activities. Adjusted total factor productivity growth rates are calculated for the two-digit SIC manufacturing industries in the United States for 1970–1996. The results indicate that including the “output” of pollution abatement activities has a measurable effect on the productivity of many industries in the manufacturing sector.     

Human capital, market imperfections, and labor reallocation in transition

In this paper, we investigate the effects of human capital and factor market imperfections on household decisions regarding labor use and reallocation in transition countries. We develop a model that accounts explicitly for heterogeneity in the supply of labor and analyze its impact on the allocation of labor. Furthermore, the effects of imperfections in the capital and labor markets on the reallocation process are modeled. Using a dataset based on a countrywide representative survey of Hungarian rural households, we estimate the effects empirically and find them to be important.

Carbon leakage revisited: unilateral climate policy with directed technical change

Using a stylized theoretical model, we argue that current economic analyses of climate policy tend to over-estimate the degree of carbon leakage, as they abstract from the effects of induced technological change. We analyse carbon leakage in a two-country model with directed technical change, where only one of the countries enforces an exogenous cap on emissions. Climate policy induces changes in relative prices, that cause carbon leakage through a terms-of-trade effect. However, these changes in relative prices also affect the incentives to innovate in different sectors. This leads to a counterbalancing induced-technology effect, which always reduces carbon leakage. We therefore conclude that the leakage rates reported in the literature may be too high, as these estimates neglect the effect of price changes on the incentives to innovate.      

Aggregate supply management in a small open economy

For a closed economy a cut in either payroll or income taxes stimulates output, but they influence the price level in different directions. In a two-sector, small open economy these conclusions are much more tenuous. Using a model that maintains equilibrium in the only two purely domestic markets, labor and nontradeables, it is established that a payroll-tax cut increases the size of the labor force, but does not guarantee higher real income. For either tax cut, prices and output move in opposite directions. In the short run when wages are “sticky,” an income-tax cut has the undesirable effect of increasing unemployment. In the face of a supply shock that reduces demand for labor, a payroll-tax cut can reestablish the original equilibrium.     

INDUSTRIAL AND AGGREGATE MEASURES OF PRODUCTIVITY GROWTH IN CHINA, 1982–2000

We estimate productivity growth for 33 industries covering the entire Chinese economy using a time series of input–output tables covering 1982–2000. Capital input is measured using detailed investment data by asset and labor input uses demographic information from household surveys. We find a wide range of productivity performance at the industry level. We then show how these industry growth accounts may be consistently aggregated to deliver a decomposition of aggregate GDP growth. For the 1982–2000 period aggregate TFP growth was 2.5 percent per year; decelerating from a rapid rate in the early 1980s to negative growth during 1994–2000. The main source of growth during the 1982–2000 period was capital accumulation, with a small negative contribution from the reallocation of factors across industries.     

GDP Growth Accounting: A National Income Function Approach

In this paper, we provide a decomposition of GDP growth that is complete and exact for the translog national income function and for the Törnqvist index of real GDP. The contributions of changes in output quantities, factor prices and total factor productivity are identified. Special consideration is given to foreign trade, with imports treated as a negative output. Annual estimates for the United States are reported for the period 1948–98.     

NATIONAL PRODUCT AT CONSTANT PRICES IN THE FEDERAL REPUBLIC OF GERMANY

With few exceptions, only cormmodity flows and values which can be determined by means of commodity flows (flows of goods and services) are calculated in constant prices in the official national accounts of the Federal Republic of Germany. Figures an the industrial origin and the final use of the national product are published, the former according to thirty industries, the latter according to the major types of uses of which in particular private consumption expenditure has been further analysed. The computations at constant prices are based on market prices and not on factor costs. It is only on this basis that a uniform valuation of the production and the expenditure side can be made since the turnover tax, which is the most important indirect tax, is contained in the elements of final demand in varying shares and cannot be eliminated (the tax is part of the price and has cumulative effect). The computation at constant prices presupposes a breakdown of the values in current prices according to quantities and prices. This raises a number of problems, e.g. because seller and buyer may consider differing aspects-production costs, technical attributes, etc., on the one hand, and use etc., on the other hand. In part there exist only vague ideas, or no ideas at all, as to what is to be considered-from a theoretical point of view-as quantity and price. In other cases the two values can only with great difficulties, if at all, be quantified, or there exists no market price and only the production costs are available. The author deals in greater detail with differences in quality and new commodities, the determination and treatment of quantities and prices for services, in particular for trade services (services attached to goods), the computation of government services at constant prices considering the development of productivity in public service, the determination of the values calculated as balances, above all the treatment of changes in the terms of trade for net exports of goods and services, the computation of the contributions of industries to the gross domestic product and, finally, the reconciliation of the production and the expenditure side. In a third section the author deals with index formulae and the base year. In the majority of cases values are deflated; partly, however, they are currently adjusted by means of volume and quantity data. On the production side the two methods are in part combined. In a concluding section a survey is provided of the computation methods used in the Federal Republic of Germany and on the available material for the computations. Mention is made of depreciation at constant prices.
