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.     

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.     

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.     

Benefits and unemployment in an open economy: an equilibrium analysis

This paper examines the relation between uemployment compensation and unemployment in The Netherlands. This relation is studied by menas of a small macroeconomic model for an open economy that assumes equilibrium in the labour market and on the current account. The model yields an elasticity of unemployment to benefits of 1.0, which is high compared to microeconomic research and the outcomes of disequilibrium models for The Netherlands. According to the model, a rise in the ‘wedge’ (i.e. the difference betweenn real labour cost and real net wages) leads to an increase in unemployment, whilst shifting this wedge from the employers to the employees induces a fall in unemployment.     

Foreign firm entry in an open economy: the case of Portugal

The purpose of this paper is to analyse the entry process of foreign direct investment (FDI) in Portuguese industrial sectors. Portugal presents an interesting case where firms enter to take advantage of export opportunities. The results suggest that foreign firms possess the ability to overcome existing entry barriers that affect domestic firms. Apparently, foreign firms have different expectations about profitability than domestic firms, possibly due to foreign firms’ export-orientation to the rest of the European Union (EU). They appear to desire industries where other foreign firms have clustered. Above all, it appears that these foreign firms enter industries to exploit Portugal's chief location advantage in Western Europe: low wages. Portugal's FDI experience is relevant to other countries that have opened their economies to greater trade and investment and attracted export-oriented firms.     

Testing for short-run money neutrality in a small open economy: The case of Canada

This paper adopts an econometric methodology which is based on standard nested-hypotheses testing in order to test the policy ineffectiveness proposition in the context of the Canadian economy. It thus avoids some problems associated with the non-nested hypotheses framework used by Barro and numerous other writers. The substantial openness of the Canadian economy is taken into account through the use of a Mundell-Flemming aggregate demand side. The supply response of the economy is carefully modelled, in the same context, and the familiar Sargent-Wallace aggregate supply function is derived as a special case of a more general Keynesian function — by assuming instantaneous adjustment of prices to costs. Empirical tests based on a data sample spanning the period of Canada's recent experience with flexible exchange rates are unfavorable to the policy ineffectiveness proposition.     

The demand for money in an open economy: the United Kingdom

Most previous studies have estimated the demand for money without paying too much attention to developments in the foreign exchange markets. In light of the fact that any development abroad and in the foreign exchange markets could have implications for domestic stabilization, we make an attempt to incorporate such developments into the demand for money in the United Kingdom. More precisely, after incorporating a measure of real effective exchange rate of the British Pound into a dynamic money demand function, we estimated it for the UK using quarterly data over 1973–87 period. By relying upon the Akaike' Final Prediction Error criteria to select the optimum number of lags, it is shown that in addition to income and interest rate, the real effective exchange rate exerts significant effect on the UK demand for money in the short run as well as long run.     

Bayesian estimation of the output gap for a small open economy: The case of Canada

We introduce a novel approach for estimating output gaps for small open economies. Identification is based on a multivariate trend-cycle decomposition in which transitory exchange rate movements are linked to the output gap and inflation. The model is then applied to Canadian data.     

Estimating the natural rate of interest in an open economy

The concept of the natural or equilibrium rate of interest has attracted a lot of attention from monetary policymakers in recent years. Most attempts to estimate the natural rate use a closed-economy framework. We argue that in the face of greater integration of global product and capital markets, an open economy framework is more appropriate. We provide some initial estimates of the natural rate for the USA and Japan in a two-country framework. Our identifying assumptions include a close relationship between the time-varying natural rate of interest and the low-frequency fluctuations of potential output growth in both the home country and the foreign country. Our results suggest that the natural rates in both countries are mainly determined by their own trend growth rates of potential output. Nevertheless, the other country’s trend growth plays an important role in several specific periods. The gap between the actual real interest rate and our estimated natural rate offers valuable insights into the recent stance of monetary policy in both of these two countries.     

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.     

Inflation and nominal tax system in an open economy

This paper provides an analysis of the implications of the interaction between inflation and a tax system which is not fully indexed within the context of an open economy. The model used is characterized by perfect foresight, full employment, imperfect substitutability between domestic and foreign assets, and an endogenous stock of capital. Three distinct channels through which an increase in the inflation rate disturbs the initial equilibrium are analysed separately. The global effect is then discussed with respect to the position of the economy as debtor or creditor to the rest of the world. The financing of the public deficit is also briefly discussed.     

Progressive taxes and automatic stabilization in an open economy

In a simple model with a fixed exchange rate, more progressive taxes are likely to lead to a fall in the multiplier for autonomous expenditure. The effect on the multiplier for an autonomous wage shock may go either way, and increased progressivity may change the sign of this multiplier. The wage bargaining is modeled as a trade-off between employment and real disposable income. Depending on them weight attached to employment and the way expectations are formed, more progressivity may contribute to stabilize rather than destabilize this wage formation process. Indexation of taxes to imported inflation seems preferable to alternatives.     

Income inequality and economic growth in an open economy

Income inequality has a strong impact on fiscal policy when majority voting enables those individuals with less-than-average income to decide on tax rates. This study analyzes the impact on economic growth of income inequality in an open economy where tax revenues are partially used for international transfers. In any case, income inequality is harmful for growth. In an economic union, positive effects of international integration raise the growth rate as long as net transfers do not grow proportionally. In a political union, unionwide voting makes distributive politics depending on the union's median voter. In this case, additional output growth on aggregate level is a necessary, but not sufficient condition for a majority of voters to accept union membership.     

Determinants and Forecast of Price Level in India: a VAR Framework

The theoretical association of money supply and exchange rates with prices has been empirically established and shown to be dominant in explaining changes in price levels in India. However, post liberalisation, studies have shown price levels to be impacted by several other factors as also, weakened influence of the traditional factors established by theories. This study aims to find the determinants of price level for the period 1994–2008 using a Vector Autoregression model and test the predictive ability of the model. Our results show shorter and smaller impact of change in money supply and nominal effective exchange rate on price levels. Both money supply and nominal effective exchange rates are found to Granger-cause Consumer Price Index. But, impulse response functions show that the impact of shocks from money supply and nominal effective exchange rates on consumer prices peaks after two lags and is short-lived. Forecast error variance decomposition shows that these demand side factors contribute only 6 % of the forecast error variation in Consumer Price Index.

     

Price level targeting and the delegation issue in an open economy

A weight-conservative central banker setting policy with discretion and stabilizing the real exchange-rate-adjusted (REX) price level and the output gap can replicate the behavior of the rate of REX inflation and the output gap under policy from a timeless perspective.     

A cointegrated structural VAR model of the Canadian economy

This paper implements a cointegrated structural VAR model of the Canadian economy using quarterly data over the period 1964–1994. The dynamic properties of the estimated model are compared to the predictions of a simple textbook macro model. Four long-run equilibrium relationships are tested: (i) consumption–income; (ii) consumption–wealth; (iii) money demand; and (iv) the Fisher equation. The empirical results obtained are generally consistent with the predictions of the textbook model's long-run implications, although level shifts are observed in the consumption/income and the wealth/income ratios. Similarly it is found that there was an increase in the ex post real interest rate, implying a level shift in the Fisher relation, following the Bank of Canada's policy change towards a stable price level target.     

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.     

Sustainability of an economy with an exhaustible resource: A viable control approach

We examine the conditions for the sustainability of a production–consumption system based on the use of an exhaustible natural resource. Instead of studying the environmental and economic interactions in terms of optimal control, we focus on the viability of the system, defined by a set of constraints combining guaranteed consumption and a stock of resources to be preserved at all times, which refers to a Rawlsian intergenerational equity perspective. Using the mathematical concept of viability kernel, which makes it possible to deal with the consistency between constraints and controlled dynamics, we exhibit the sustainable technological configurations and, whenever possible, the policy options and environmental-economic states required to obtain a perennial system. We point out the flexibility of the sustainable “extraction–consumption” choices and we show how they are neither reduced to constant consumption paths nor to Hartwick’s rule. Numerical simulations illustrate the general results.
