Creative destruction and unemployment in an open economy model

I develop a model of endogenous economic growth and search and matching frictions in the labour market. I study the effect of trade liberalization between two identical economies on long‐run unemployment and show that bilateral trade liberalization has a steady state effect on unemployment that is negative for countries with a relatively larger R&D sector and positive for countries with a smaller R&D sector.     

Expectation traps in a new Keynesian open economy model

This paper illustrates that the presence of a money demand distortion in an otherwise standard new Keynesian open economy model results in multiple discretionary equilibria that arise in the form of expectations traps. If private sector inflation expectations become sufficiently unanchored, the model predicts that a monetary authority can easily be trapped into validating these expectations, thereby pushing the economy to a lower welfare equilibrium. Given the ease with which expectation traps arise in the presence of international linkages, the main result presented here suggests that maintaining well-anchored inflation expectations is a critically important policy goal for central banks in open economies.     

A general-equilibrium intertemporal model of an open economy

Summary This paper develops a very general (general-equilibrium) intertemporal model of a country engaged in international trade which can be used to address a wide variety of issues of interest — in particular, econometric application — under the assumption that prices of tradable commodities (consumer goods and capital goods) and the interest rate are exogenous to the country. It allows for an arbitrarily large number of commodities which are distinguished into seven categories and for finite or infinite periods of time. This model can be used to draw various policy conclusions. We investigate how current net imports, the balance of payments on current account, current consumption expenditure, next-period bondholdings, current wealth, and current internal prices will react to exogenous changes in current external prices, the current interest rate, current taxes, current factor endowments, and current-period bondholdings. This paper also considers the integrability of net-import demand functions.Work supported by National Science Foundation grant SES-8607652.

A dynamic small open economy model with involuntary unemployment

Abstract It is well known that real business cycle small open economy (SOE) models rely on Greenwood, Hercowitz, and Huffman (1988) preferences to match the countercyclical trade balance observed in open economies, as well as other second moments, while standard preferences à la King, Plosser, and Rebelo (1988) are commonly labelled ‘ineffective,’ owing to their inability to yield the countercyclical trade balance. In this paper, I show that an SOE model with standard preferences and ‘involuntary’ unemployment with efficient risk sharing can obtain a countercyclical trade balance and match main empirical regularities in small open economies.     

Capital utilization and habit formation in a small open economy model

Abstract.  This paper shows the effects of endogenous capital utilization and habit formation in consumption on the predictions of a small open economy model calibrated to Canada. Capital utilization improves the fit of the model by increasing the volatility of output, investment, and hours worked, while habit formation improves the fit of the model by improving the dynamic properties of consumption and the current account. It is also shown that while shocks to the world interest rate sometimes improve the fit of the baseline model, they do not improve the fit of the model with capital utilization and habit formation.

Dynamic scoring of tax reforms in a small open economy model

We examine dynamic revenue effects of a permanent tax cut on labor and capital income using a small open two-sector dynamic general equilibrium model. We use a dynamic scoring technique to calculate long-run as well as transitional effects on fiscal revenue when a tax cut is financed by either a lump-sum tax or consumption tax. We show that the revenue loss from an income tax cut becomes substantially smaller when agents can use international financial markets compared to the case of the closed economy. Responses of tradable and nontradable sectors to the capital income tax cut display a stark contrast in both long-run equilibrium and transitional dynamics due to different factor intensities. Capital income tax cut in the tradable sector is the most efficient policy instrument in terms of minimizing fiscal revenue loss. These simulation results suggest that fiscal sustainability issue when implementing a tax cut could be overstated.     

Investment-specific shocks and external balances in a small open economy model

Abstract.  We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment-specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian counterparts. We find that the model captures the dynamics in investment and in the trade balance better than special cases of the model where either one of the productivity shocks is omitted. More specifically, the model matches the variance of the trade balance-output ratio, its correlation with output and its autocorrelation. It also matches the output-investment correlation.     

A model of a small open economy integrated in a monetary union

This paper develops a model of a small open economy integrated in a monetary union, which is a nontrivial technical extension of the existing small open economy model. The model is used to study the monetary transmission mechanism in Portugal.     

A short-run general equilibrium model for a small,open economy

This paper introduces some features observed in developing countries into a CGE model. In particular, quantitative restrictions on exports and imports are incorporated and quota-derived rents are included as a source of income. The economy is assumed to be small only on the import side, such that export prices are endogenous. A distinction between traded and treadeable goods is introduced, together with the possibility of ‘water in the tariff’. Thus, the law of one price need not hold. Another key feature is the modelling of supply with unutilized capacity. Thus, excess demands clear by price changes, output adjustments, or imports, depending on the degree of capacity utilization, the tradeability of the good, and the trade regime. An empirical application of the model shows that in a GE context, import quotas can worsen the trade balance while lowering real income and the real wage rate.     

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.     

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.     

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.     

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.     

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.     

A structural VAR business cycle model for a volatile small open economy

New Zealand is a small economy exposed to a volatile climate, relatively volatile international trade prices, and its exposure to international financial markets has increased markedly since economic reforms in the 1980s. This paper applies identification techniques suggested by Cushman and Zha [Cushman, D.O. and Zha T.A., 1997. Identifying monetary policy in a small open economy under flexible exchange rates, Journal of Monetary Economics, 39, pp. 433–448.], Zha [Zha, T.A., (1999). Block recursion and structural vector autoregression, Journal of Econometrics, 90, pp. 291–316.] and Dungey and Pagan [Dungey, M. and Pagan, A., 2000. A structural VAR model of the Australian economy, The Economic Record, 76, pp. 321–342.] to develop a large four block structural VAR model of the New Zealand business cycle to capture these features. The model reveals that climate and international trade price shocks have been more important sources of business cycles fluctuations than international or domestic financial shocks. Furthermore, the model does not encounter the price and exchange rate puzzles that have bedevilled attempts to identify monetary policy shocks in small open economy SVAR models.     

A structural model of price and exchange rate dynamics in a small open economy

Conclusions A major result following from the analysis of ourstructural model of inflation under flexible exchange rates is that there is no such thing asstructural inflation in the long run. Long-run inflation rather becomes a purely monetary phenomenon if exchange rates are flexible and if on an international level functioning capital markets are postulated. While, in the light of the assumptions made in Part III, this finding is not nearly as paradoxical as it may appear at first sight, it can hardly be overemphasized considering the ongoing theoretical discussion and the empirical research on the Scandinavian approach to inflation and recalling that the Scandinavian model is basically intended to picture equilibrium dynamics.The results concerning equilibrium price and exchange rate dynamics also apply to the equilibriumlevels of prices and the exchange rate, i. e., the equilibrium price level depends exclusively on monetary factors while the equilibrium exchange rate is determined by a purchasing power parity element and the structural productivity gap component.Turning to the results of our analysis of disequilibrium dynamics, the overall picture does not change very much. Here the qualitative pattern of adjustment of both prices and the exchange rate is again completely independent of structural variables, but is exclusively determined by four adjustment coefficients. However, the particular quantitative values assumed by prices and the exchange rate during the adjustment process do indeed reflect the impact of the productivity gap.No conclusions can be derived from our model on the amount of time it takes to return to the neighbourhood of equilibrium once the economy has been subjected to some kind of external shock. A casual examination of post-1973 developments and especially the Swiss experience suggest, however, that in the case of a disturbance as, e. g., in the form of a monetary contraction (relative to the rest of the world), the economy may take so long to return to the neighbourhood of long-run equilibrium that the negative real consequences of the overvaluation of the domestic currency during the adjustment process provide a momentous rationale for short-run stabilization interventions in the foreign exchange market.We should like to thank Peter Bernholz and an anonymous referee for helpful comments on a previous version of this paper.     

Relative labor demand in an open economy

This paper contributes to the discussion concerning the nature of the well-documented worsening of wage and employment inequality in western economies during the past three decades. It critically discusses the use of the traditional Heckscher and Ohlin approach to analyze the distributional effects of international competition. The paper also discusses an innovative theoretical scenario in order to effectively explain the empirical observations. The model overcomes the problem of a dichotomized labor market, which is an unfavorable result of the traditional approach. Furthermore, the factor-biased character of the technological change becomes endogenous as the strength of foreign competition and the induced incentives for technical innovations are taken into consideration. This paper was presented at the 55th International Atlantic Economic Conference, Vienna, Austria, March 12–16, 2003.     

The Southampton econometric model building unit : Some lessons learned

This paper draws on the author's experience as a research fellow on the Southampton Econometric Model Building Unit in suggesting that there is a case for large-scale, structural, disaggregated econometric models. This is particularly so if, like SEMBU, the aim is to improve both economic theory and economic policy advice rather than simply to forecast actual futures. It is argued that for such an approach to model building to be successful, funding agencies should adopt a long-term view and the Central Statistical Office and other data generating bodies should become much more closely involved with the model-building unit. This latter cooperation could prove mutually beneficial.
