Politically Motivated Fiscal Deficits: Policy Issues in Closed and Open Economies

In this paper we reconsider the trade-off between rules and discretion in fiscal policy in the presence of politically motivated fiscal deficits. We present a model of political bias in the budget process appropriately developed to allow for tax-smoothing-motivated deficits as well as for the consideration of deficit biases in open economies. We find that endowing politically-biased governments with the ability to respond to economic shocks with deficit finance will not exacerbate the existing biases. In an open economy, the ability to borrow abroad will significantly increase the deficit. However, restrictions to public foreign borrowing will not reduce the political bias as long as the private sector has access to international capital markets at the same terms as the government.     

Sustainability in Uncertain Economies

A stochastic growth model with a list of capital assets (i.e., reproducible capital, non-renewable resources, the knowledge base and institutions) is studied to evaluate the effects of different sources of uncertainty on sustainability. It is also discussed which measure can serve as an index of intergenerational welfare to evaluate sustainable development under uncertainty. The aim is to consider a more comprehensive setting than is usually explored in the literature and to generalize Arrow, Dasgupta and Mäler results to the case of uncertainty.     

Price Stability in Open Economies

This paper studies the theoretical conditions under which price stability is the optimal policy in a two-country open-economy model with imperfect competition and price stickiness. Special conditions on the levels of country-specific distortionary taxation and the intratemporal and intertemporal elasticities of substitution need to be satisfied. These restrictions apply to both cooperative and non-cooperative settings. Importantly, we show that cooperative and non-cooperative solutions do not coincide despite market completeness and producer currency pricing. We study the conditions under which quadratic approximations of single countries' welfare can be correctly evaluated by relying only on log-linear approximations of the equilibrium conditions.     

The Rise, Fall and Sustainability of Capital-Resource Economies

In debates about green accounting it is sometimes argued that a positive value of aggregate investments indicates that an economy is developing sustainably. Asheim (1994) and Pezzey (1994) have shown that this is wrong, using a version of the well-known Dasgupta–Heal economy (with one capital and one non-renewable resource stock) as a counterexample. Asheim's proof referred to the unproved assumptions that in such an economy a higher rate of time preference induces higher initial consumption and vice versa, and that "optimal" consumption is initially rising and then falling. Here we show that these assumptions do hold true under certain circumstances, thereby also proving some of Dasgupta and Heal's other conjectures about sustainability.     

Environmental Policy in Open Economies and Monopolistic Competition

This paper analyses the implications of international trade for non-cooperative environmental policy in the case of local production externalities. A particular focus is on the potential effects of regulations on the variety of goods and the resulting international spillover caused by trade. A tougher domestic standard negatively affects the utility of the households abroad, since such a policy reduces their variety of imports (due to fewer domestic product inventions) or their consumption of each imported brand (due to higher import prices). Ignoring the negative spillover, non-cooperative governments implement inefficiently strict standards in equilibrium. In contrast to this clear-cut inefficiency result, the impact of international trade on the state of the environment is ambiguous.     

Inflation in Open Economies with Complete Markets

This paper uses an overlapping generations model to analyze monetary policy in a two-country model with asymmetric shocks. Agents insure against risk through the exchange of a complete set of real securities. Each central bank is able to commit to the contingent monetary policy rule that maximizes domestic welfare. In an attempt to improve their country’s terms of trade of securities, central banks choose to commit to costly inflation in favorable states of nature. In equilibrium the effects on the terms of trade wash out, leaving both countries worse off. Countries facing asymmetric shocks may therefore gain from monetary cooperation.     

Prices,Productivity and Wage Bargaining in Open Economies*

According to the standard union bargaining model, unemployment benefits should have big effects on wages, but product‐market prices and productivity should play no role in the wage bargain. We formulate an alternative strategic bargaining model, where labour and product‐market conditions together determine wages. A wage equation is derived and estimated on aggregate data for four Nordic countries. Wages are found to depend not only on unemployment and the replacement ratio, but also on productivity, international prices and exchange rates. There is evidence of considerable nominal wage rigidity. Exchange rate changes have large and persistent effects on competitiveness.     

Intertemporal Budget Policies and Macroeconomic Adjustment in Indebted Open Economies

This paper analyzes the role of government intertemporal budget policies in a growing open economy including nominal assets in the presence of an upward sloping supply of debt. This introduces transitional dynamics that influence the effects of government policy instruments on economic growth and the long term fiscal liability. It is shown that capital income taxes or a combination of tax‐cum‐expenditure or government expenditure alone can balance the long term intertemporal government budget constraint. However, those results are shown to depend critically upon the extent of distortion in capital flows brought about the upward sloping supply of debt.     

Strategic Voting for Noncooperative Environmental Policies in Open Economies

In this paper, we construct a political-economy model of strategic environmental policymaking with different degrees of product differentiation and different market structures, and examine how strategic voting decisions are affected by the choice of environmental policy instruments (tax or standard). We show that in a Cournot market structure, voters elect tax-setting policymakers who are more green than themselves when product differentiation and/or environmental externalities are more prominent. In a Bertrand market structure, they elect more green tax-setting policymakers than themselves. On the other hand, they elect standard-setting policymakers who are less green than themselves. The results confirm the advantage of the overall use of emission tax over that of emission standard regarding the welfare effect of strategic voting.     

Alternative Monetary Policy Rules for Small Open Economies

This paper examines the relative merits of alternative monetary policy rules for a small open economy. Rules considered target: the exchange rate, price level, nominal income, or a monetary aggregate. The standard framework employed in previous comparisons of these rules fails to take account of important features of small open economies. In particular, the standard framework fails to consider the effects on aggregate supply of exchange rate adjustments resulting from adherence to policy rules. Incorporating these effects is shown to weaken the case for targeting nominal income and, more generally, to complicate the ranking of policy rules.     

Foreign Direct Investment into Open and Closed Cities

This article argues that the more open a city is to immigration, the more likely it is to welcome – and hence also receive – foreign direct investment (FDI). If immigration is allowed to complement the inflow of foreign capital, urban rent rises by more. This extra rise in rent aids in appeasing owners of capital specific to local traditional industries who else become worse off as FDI flows in. The article's model may help give a simple alternative explanation of why urban centers such as Hong Kong, Singapore, Dublin or many cities on China's Eastern coast have received so much more FDI per capita. These cities could draw on a nearby pool of extra labor that – by driving rents up and keeping wages down – may have been decisive in the political struggle over whether to let foreign direct investors in.     

Optimal Environmental Policy Differentials in Open Economies under Emissions Constraints

Is there a case for preferential treatment of the exposed sector in an economy when compliance to an aggregate emissions constraint induced by an international environmental agreement is mandatory? This question is being debated in many countries in the context of the implementation of the Kyoto Protocol. We address the issue in a general equilibrium framework and theoretically cover several market structures, including perfect competition, the large country case and oligopoly. We identify the conditions under which preferential treatment of the exposed sector is not warranted from the point of view of maximizing social welfare. In addition, we demonstrate that in the case of oligopoly, instituting a more stringent environmental policy on the exposed sector might be profit-enhancing for this sector. This finding lends theoretical support to a specific interpretation of the Porter hypothesis.     

Constant Consumption Paths In Open Economies With Exhaustible Resources

We examine the effects of international trade on the paths of investment which maintain consumption constant over time in each country, each of which produces an essential exhaustible resource such as oil. For countries identical except for the sizes of their oil stocks, the investing of own oil rents in machine capital will not result in constant consumption in each country. Adjusted rent-investment strategies are developed which do yield constant consumption in each country. We also report results on the link in each country between its consumption levels and aggregate current wealth.     

The World Is Not Enough! Small Open Economies and Regional Dependence

In this paper, we explicitly introduce regional factors into a global dynamic factor model. We combine new open economy factor models (emphasizing global shocks) with the recent findings of regional importance in the business cycle synchronization literature. The analysis is applied to a large panel of domestic data for four small open economies. We find that global and regional shocks explain roughly 30 and 20 percent, respectively, of the business cycle variation in all countries. While global shocks have most impact on trade variables, regional shocks explain a relatively large share of the variation in cost variables.
