Intersectoral transfer of labour in a small open economy

This paper deals with normative and positive aspects of labour transfer processes in the context of a small open two-sector economy. Labour is not homogenous in the short run because transfer of labour is assumed to involve training costs in terms of output foregone when workers already possessing industry-specific knowledge are training new workers. The efficient transfer plan for this economy is characterized, and the determinants of the optimal rate of transfer derived. Upon examination of the competitive price system supporting the efficient plan, the first-best adjustment assistance policy is found, assuming real wages are sticky.     

Rural-urban migration,population and labour allocation: labour surplus models and alternatives

The author examines the relationship between the existence of a labor surplus in rural areas and rural-urban migration using various modeling techniques. Particular attention is given to the situation in developing countries.     

Lost in transition: the costs and consequences of sectoral labour adjustment

Abstract This paper uses an equilibrium search and matching model to study Canada’s sectoral labour adjustment in 2002–2006 during an increase in global commodity prices and exchange rate appreciation. I estimate economically significant adjustment costs for the aggregate economy in this episode and demonstrate that difficulty in transferring skills between jobs for individual workers can be an important contributor to these aggregate costs. The analysis also demonstrates that the level of unemployment benefits impacts the economy’s sectoral composition, its aggregate productivity, and the speed of its adjustment to shocks.     

Rationing in an open economy: Fix-price equilibrium and two-gap models

Two-gap models have been criticized severely for the lack of realism of their assumptions but are still prominent in development planning and, implicitly, in discussions of short-run policy problems. Here the model's applicability outside a command economy is considered by comparing it with a rationing model with proper micro-foundations. It is shown that the two-gap model in general violates fix-price equilibrium properties but that the fix-price model generates quite similar results.     

Long-run sectoral development: Time-series evidence for the German economy

In economic development, long-run structural change among the three main sectors of an economy follows a typical pattern with the primary sector (agriculture, mining) first dominating, followed by the secondary sector (manufacturing) and finally by the tertiary sector (services) in terms of employment and value added. We reconsider the verbal theoretical work of Fourastié and build a simple model encompassing its main features, most notably the macroeconomic influences on the sectoral development. Estimation and analysis with German data for the period 1850–2001 show that this model is quite capable of replicating the empirical facts.     

Welfare and sectoral productivity shifts in a small open economy with imported agricultural inputs: The case of Sub-Saharan Africa

This paper studies the impact of sectoral productivity growth on welfare in Sub-Saharan Africa. Using the analytical framework of a DSGE model, the main finding is that, for the estimated values of structural parameters, the allocation of scarce resources to the tradable agricultural sector for boosting productivity leads to a greater increase in overall welfare than would be the case if they were allocated to the non-traded goods sector.

     

Shadow pricing of labour and capital in an economy with unemployed labour

This paper derives the shadow prices of labour and capital to be used in the public sector in a situation of unemployment. The setting considered is that of a three-good, two-period general equilibrium model. Then shadow prices are compared to their corresponding market prices and shown to closely depend on own and cross-elasticities of supply and demand for labour and investment. In the first part, a rigid wage rate is the sole source of distortion; then, a tax on capital income is introduced so that our formula for the social rate of discount can be contrasted with that of Harberger, Sandmo and Drèze.     

The impact of sectoral shifts and the aggregate labour market on unemployment duration

This study investigates the effects of sectoral shifts among industries on unemployment duration. These effects are decomposed into two subeffects: the overall effect and the specific industrial effect. The former is equal for all of the unemployed in all industries, while the latter depends on the tightness of the demand for labour of the industry in question. In addition, the impact of the aggregate labour market on unemployment duration is also explored. The empirical results show that most of the overall and all of the specific effects are significant, indicating that the sectoral shifts among industries as well as the aggregate labour market do in fact impact unemployment duration, and that the effects on unemployment duration vary in terms of their tightness in the different industrial labour markets.     

Taylor rules in the open economy

Taylor rules, which link short-term interest rates to fluctuations in inflation and output, have been shown to be a good guide (both positively and normatively) to the conduct of monetary policy. As a result they have been used extensively to model policy in the context of both closed and open economy models. Their determinacy properties have also been analysed in the context of closed and, to a more limited degree, in small open economy models. In this paper, we extend the analysis of the determinacy properties of Taylor rules to the case of a benchmark two-country model. When the rules are specified in terms of output-price inflation we confirm and extend the conventional results from the closed economy literature—satisfying the Taylor principle is the key to ensuring determinacy, although the presence of backward-looking price-setting can affect the determinacy properties of the two-country model. However, the conventional results do not hold when we replace output-price inflation with consumer price inflation in the specification of the rule. In this case, Taylor rules which satisfy the Taylor principle will be indeterminate, unless there is an unusually large home bias in consumption. Similar indeterminacy problems arise when one country targets CPI inflation and the other output-price inflation. In this case we show that, even if determinacy is achieved, large spillovers may occur between countries.     

Pure rent taxation and allocation of capital in a two-sector open economy: A long-run analysis

In this paper, the long-run incidence of a tax on pure rent is analyzed in an OLG two-sector small open economy, in which one sector produces a capital good and one sector a consumer good. Contrary to what is obtained in a one-sector closed economy, a land rent tax does not necessarily foster nonhumam wealth accumulation and capital formation. The accommodating scheme for the government budget plays a crucial role for the effects of pure rent taxation. A rent tax stimulates nonhuman wealth if distortionary taxes on wealth or on income from nonland inputs are alleviated. The mechanism spurring capital formation is brought into action, instead, only when the rent tax is matched by a fall in capital taxation or, if the capital sector is capital intensive, by an increase in government spending on the capital good.     

Trade and technological explanations for changes in sectoral labour demand in OECD economies

This paper sets out to establish the main determinants of variations in the demand for aggregate labour in manufacturing and service sectors (22) for a cross-section of OECD countries (14). A relatively new panel data set is employed in the analysis, the OECD's International Sectoral Data Base. Preliminary analysis revealed that the ‘within’ sector variation in the wage share dominated overall variation for most countries and time periods. A separate dynamic model was thus generated to explain the ‘within’ sector variation in the wage share. This model contained real wages, output, the capital stock, technological change (total factor productivity) and trade (the imports to value-added ratio) as independent variables. In addition the wage level was also interacted with these explanatory variables on the presumption that skill is positively correlated with the level of wages. Because of the potential for simultaneity bias, estimation was conducted by IV and OLS. The main findings were that the capital stock and technological change were the main determinants of shifts in labour demand. While some countries reported the trade variable as significant its influence was only of slight importance in most cases. The interaction terms proved to be significant in a large number of countries. Some evidence was found that capital and technological were complementary with skill. Overall it was found that broad agreement existed across countries in the factors which influence labour demand despite considerable differences in the cross-country nature of labour market institutions.     

Separability and capital aggregation in sectoral models of US production

Separability plays a fundamental role in applied studies of production inasmuch as it provides for consistent aggregation and allows multi-stage estimation of models with many inputs. This paper examines whether two types of capital, structures and equipment, are weakly separable from labour and energy and materials in sectoral models of US production, and provides an assessment of the effects of maintaining capital separability. The study focuses on the elasticity of substitution as a measure of input association and associated standard errors and confidence intervals based on bootstrapping. Elasticity estimates and tests indicate that capital separability is generally inconsistent with data representing sectoral US production. Elasticity sign, however, appears robust to capital aggregation and performs especially well as an indicator of input association.     

Modelling the business cycle of a small open economy: The Reserve Bank of New Zealand's DSGE model

We describe the underlying structure of the new forecast and policy model used at the Reserve Bank of New Zealand and evaluate its ability to explain New Zealand data. Unlike other estimated small-open-economy DSGE models, we find that more than one third of the domestic GDP growth is driven by foreign shocks. The elevated contribution of foreign shocks to the domestic economy is driven by our decision to exclude mapping export demand to data on world GDP. Estimating our model without any foreign demand data limits the response of exports to the real exchange variations. This feature makes exports and, consequently, domestic GDP much more sensitive to variations to foreign demand and raises the importance of foreign shocks to the domestic business cycle. Furthermore, our analysis suggests that a model with “adaptive” expectations is preferred by the data relative to the version of the model with “rational” expectations. In that case, the model explains nominal variables using on average much smaller shocks.     

Informality in an economy with active labour courts

Job regulations and the justice branch interfere on several aspects of labour contracts. We build a model which explores the role of labour courts on the wage distribution in both formal and informal sectors. We obtain that the presence of active labour courts produces a negative relation between the wage gap and the productivity of the worker, a regularity documented in the empirical literature. Active labour courts also reduce informality of unskilled workers but do not have an impact on informality of skilled workers. Some elements and implications of our model are tested using Brazilian data.     

Wage norms in an open economy

Zusammenfassung Das Zusammentreffen einer Beschleunigung des Preisauftriebs und einer Erhöhung der Arbeitslosigkeit in den OECD-Ländern in den sechziger und siebziger Jahren überzeugte viele Wirtschaftswissenschafter und Wirtschaftspolitiker, daß es einer Einkommenspolitik bedürfe, um die diskretionäre Marktmacht von Unternehmen und Gewerkschaften einzuschränken. Zwei wichtige Varianten der Einkommenspolitik sind die produktivitätsorientierte Lohnpolitik, die das Wachstum der Geldlöhne vom Wachstum der gesamtwirtschaftlichen Produktivität und der gesamtwirtschaftlichen Preissteigerung abhängig macht, und das Skandinavische Modell, in welchem die Erhaltung der internationalen Wettbewerbsfähigkeit dadurch garantiert wird, daß das Wachstum der Geldlöhne gleich der Summe des Produktivitätswachstums im exponierten Sektor und der Preissteigerung der handelbaren Güter (in heimischer Währung) ist. Dieser Aufsatz zeigt, daß beide Arten der Einkommenspolitik äquivalent sind. Er untersucht auch die Rolle der Wechselkurse in diesen Modellen und verwendet das Ergebnis, daß in einer umfassenden Einkommenspolitik Lohnzurückhaltung durch eine Preispolitik in der Form einer Wechselkurspolitik ergänzt werden muß, um historische Ereignisse in einigen Ländern zu interpretieren.     

Kaldorian dynamics in an open economy

In this paper, we formulate a Kaldorian business-cycle model in a small open economy. We consider the possibility of capital mobility, and both the system of fixed exchange rates and that of flexible exchange rates are studied. We investigate how changes of the parameter which represents the degree of capital mobility affect the dynamic characteristics of the model. Some numerical simulations are performed based on the analytical model.     

Dynamic collusion in an open economy

This paper provides an example of how opening a country to trade may decrease competition in an industry. This result, counter to conventional theory, occurs when one considers multi-period games.     

What to stabilize in the open economy*

We consider the question how “best” to maintain price‐level stability in an open economy, and evaluate three possible policy choices: (a) a constant money growth rate rule; (b) a fixed exchange rate; and (c) a policy of explicit commitment to a price‐level target. In each case we assume that policy is conducted by injecting reserves into or withdrawing reserves from the “banking system.” In evaluating the three regimes, we adopt the criterion that the “best” policy should leave the least scope for indeterminacy and “excessive” economic volatility. In a steady‐state equilibrium, the choice of regime is largely irrelevant; any steady‐state equilibrium under one regime can be duplicated by an appropriate choice of the “control” variable under any other regime. However, we show that the sets of equilibria under the three regimes are dramatically different. When all countries follow the policy of fixing a constant rate of money growth, there are no equilibria displaying endogenously arising volatility and there is no indeterminacy of equilibrium. Under a regime of fixed exchange rates, indeterminacies and endogenously arising fluctuations are impossible if and only if the country with the low “reserve‐to‐deposit” ratio is charged with maintaining the fixed rate. Finally, when one country targets the time path of its price level, under very weak conditions, there will be indeterminacy of equilibrium and endogenously arising volatility driven by expectations.     

Price controls in an open economy

Wage and price controls have been increasingly called for as Western economies have experienced periods of stagflation. Part of their attractiveness has been due to the belief that they are an appropriate instrument to deal with a country's unsatisfactory balance-of-payments position. This paper evaluates the appropriateness of an incomes policy in an open economy. An optimally structured incomes policy, derived for a simple inflation model, is examined under alternative exchange rate regimes. The model, in the tradition of models by Gordon, Hicks, and Okun, is characterized by two output markets-one a flexible price market and one characterized by markup pricing-and by a single labor (input) market. This model is then used as the constraint set in a dynamic optimization problem. Both analytical and simulation results are presented. The results suggest that a direct price control program is not appropriate in an open economy.
