GDP nowcasting: application and constraints in a small open developing economy

Despite data limitations, an attempt is made to find out if a GDP nowcasting model can provide reliable forecasts for a small open economy. Two competing Bayesian vector autoregressive models are tested rigorously to obtain the optimal model by minimizing in-sample forecasting errors. The main finding of this study is that GDP nowcasting can produce reliable results for a small open economy despite the unavailability of sufficient data sets and the lack of high frequency indicators.     

Uniqueness of asset prices in an exchange economy with unbounded utility

Summary. This paper studies conditions under which the price of an asset is uniquely determined by its fundamental value – i.e., no bubbles can arise – in Lucas-type asset pricing models with unbounded utility. After discussing Gilles and LeRoy's (1992) example, we construct an example of a two-period, representative agent economy to demonstrate that bubbles can arise in a standard model if utility is unbounded below, in which case the stochastic Euler equation may be violated. In an infinite horizon framework, we show that bubbles cannot arise if the optimal sequence of asset holdings can be lowered uniformly without incurring an infinite utility loss. Using this result, we develop conditions for the nonexistence of bubbles. The conditions depend exclusively on the asymptotic behavior of marginal utility at zero and infinity. They are satisfied by many unbounded utility functions, including the entire CRRA (constant relative risk aversion) class. The Appendix provides a complete market version of our two-period example.

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.     

Optimal oil taxation in a small open economy

The international oil market has been very volatile over the past three decades. In industrialized economies, especially in Europe, taxes represent a large fraction of oil prices and governments do not seem to react to oil price shocks by using oil taxes strategically. The aim of this paper is to analyze optimal oil taxation in a dynamic stochastic general equilibrium model of a small open economy that imports oil. We find that in general it is not optimal to distort the oil price paid by firms with taxes, neither in the long run nor over the business cycle. The general result could be reversed depending on environmental considerations and available fiscal instruments. We provide simulations to illustrate the optimal response to shocks in such cases.     

Wage-setting coordination in a small open economy*

This paper studies wage-setting coordination in a two-sector, open economy dynamic stochastic general equilibrium model. Two large sectoral unions anticipate the effects of their wage demands on aggregate variables. In an open economy, there are externalities that the unions can take into account to increase aggregate welfare, but the strategic interaction between the sectoral unions tends to erode this gain. When wage coordination takes place through a wage norm set by either of the sectors, this minimizes the strategic interaction. However, wage norms create welfare losses as sector-specific wage adjustment is required to make an efficient adjustment to shocks.     

The energy problem in a small open economy

The paper deals with the economic consequences of an oil price shock in a small open economy. The analysis along neoclassical lines is based upon a three-factor nested CES production function. The model takes account of capital accumulation. Analytical solutions for the short- and long-run are presented for a linearized version of the original model, which makes existing results more tractable.     

Exchange rate pass-through in a small open economy: the Anglo-Irish case

Bilateral import unit values are constructed to investigate the extent and speed of exchange rate and production cost pass-through into the unit values of Irish imports (total and sectoral) from the UK using Menon's (1996 Menon, J. 1996. The degree and determinants of exchange rate pass-through: market structure, non-tariff barriers and multinational corporations. Economic Journal, 106(435): 434–44.  ) mark-up model. The approach used to measure exchange rate pass-through is based on cointegration and error-correction modelling and the period of analysis is from 1979 to 1995. Full pass-through from the bilateral Irish pound–Sterling exchange rate and from UK producer costs could not be rejected for total and sectoral import unit values for the sample period 1979q1–1995q4. This implies no role for domestic competing prices in explaining the long-run relationship determining unit values of Irish imports from the UK. The results indicate that for aggregate and sectoral unit values of Irish imports from the UK pass-through is incomplete in the short-run.     

On the role of money in a business cycle model of a small open economy: The case of Spain

This paper examines the consequences of introducing a cash-in-advance constraint into a small open economy business cycle model for the Spanish case. A business cycle model is built extending Correia, Neves and Rebelo's (1995) small open economy framework and Cooley and Hansen's (1995) monetary economy. Money is introduced through a cash-in-advance constraint. The stochastic simulation of the model and its comparison to Spanish data show that the model is able to mimic i) the Dolado et al. puzzle, that is, the high volatility of private consumption for this economy; ii) the Dunlop-Tarshis observation, i.e., the negative correlation between real wages and hours worked; and iii) some cyclical features of the nominal dimension.     

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.     

The role of fiscal policy in the St. Louis model: Nonparametric estimates for a small open economy

This paper reevaluates the efficacy of monetary and fiscal policies and bidirectional causality between income and each of the policy instruments used in the St. Louis model for aggregate demand using nonparametric (or infinite parametric) spectral methods. We proceed by estimating the strength of the correlations (or partial coherences) between income and each of the policy instruments over various frequencies. Then we obtain the corresponding band regression and Hannan's efficient estimates of both the lead and lag coefficients in the St. Louis model. The analysis is carried out with seasonally adjusted quarterly data and is divided into the flexible, fixed, and managed flexible exchange rate regimes. We find that while estimates from parametric regressions yield the standard conclusions for the St. Louis model, results from the nonparametric analysis are quite different. Specifically, the results of our analysis reveal that (i) both monetary and fiscal instruments are strongly correlated with income over cycles of 10 quarters or longer for the most recent period of the managed flexible exchange rate regime, and (ii) bidirectional causality exists between income and the fiscal policy instrument. These results suggest that both monetary and fiscal policy have a long-lasting effect on aggregate demand and that bidirectional causality exists between income and policy instruments. An explanation for the existence of bidirectional causality might be that the Canadian government generally pursued a purposeful discretionary fiscal policy during the post-World War II period. Furthermore, it appears that discretionary policy action may have been anticipated by rational, farsighted, and forward-looking economic agents. Finally, our results for the flexible exchange rate and fixed rate regimes are in agreement with the Mundell-Fleming view of the role of monetary fiscal policy in an open economy.     

Stabilization policy and indeterminacy in a small open economy

This paper studies the (de)stabilizing effects of income tax rules in a two-sector small open economy with production externalities. The paper shows that in the model with positive sector-specific externalities in the investment sector and negative sector-specific externalities in the consumption sector (or positive aggregate investment externalities), a regressive income tax rule can stabilize such an economy against indeterminacy, whereas a progressive income tax rule can increase the tendency for indeterminacy to occur. This paper also studies two variants that consider an imperfect world bond market and an endogenous labor supply, respectively, and shows that the qualitative results stated above remain valid. Moreover, increasing the level of sector-specific investment externalities can decrease (increase) the minimal level of tax progressivity required for indeterminacy if the investment externalities are below (above) a certain critical value and if the negative externalities in the consumption sector are taken as given.     

Intertemporally consistent shadow prices in an open economy: Estimates for Cyprus

In the practical estimation of shadow prices, the assumption that the economy is on a steady-state growth path is often invoked, usually implicitly. Most developing countries are far from this trajectory. We derive shadow prices where the dynamic evolution of the economy is endogenously determined, important influences being initial conditions and the constraints on foreign borrowing. Hence, the resulting (dated) shadow prices of tradeables, nontradeables, labor and the accounting rate of interest (ARI) are mutually consistent. Estimates for the Republic of Cyprus show that derivations from steady-state growth can be significant, leading to large fluctuations in the ARI and thereby making the timing of investment projects crucial.

Optimal monetary policy for a small open economy

This paper focuses on the design of monetary policy rules for a small open economy. The model features optimizing behavior, general equilibrium and price stickiness. The real exchange rate is shown to affect the firm's real marginal cost, aggregate supply and aggregate demand. The welfare objective depends on the openness of the economy, and the optimal policy rule differs from that which obtains in a closed economy. The inflation versus output gap stabilization trade-off is caused by the real exchange rate. The implied optimal monetary policy regime is domestic inflation target coupled with controlled floating of the real exchange rate.     

Impact of economic uncertainty in a small open economy: the case of Chile

We construct the first news-based economic uncertainty index for Chile, which allowed us to rebuild 23 years of the history of economic uncertainty in the country and quantify its impact on the economy. We find that an increase in economic uncertainty conveys a fall in GDP, investment, and employment, even after accounting for the small open economy nature of Chile. In contrast to previous studies for big and developed economies, we do not find evidence of an overshooting effect when uncertainty dissipates; therefore, increases in economic uncertainty have negative effects on the economy, even in the long-run. Our estimates suggest that these impacts range from 10% to 20% for aggregate investment, 2.5% to 5% for GDP, and 1.3% to 4.2% for employment. Extensions suggest that economic uncertainty affects both mining and non-mining investment, with the former showing a more pronounced decline. We also find that the bulk of effect of economic uncertainty on aggregate investment is via private investment, with some short-run impacts on public investment. Moreover, compared to the GDP response, aggregate consumption responds in almost the same way to an economic uncertainty shock.     

Money and prices in an increasingly open economy: The case of Taiwan

The paper examines the price movement in an increasingly open economy like Taiwan. A theoretical model of the open-economy quantity theory is set forth which relates domestic inflation rate to inflation of world price, monetary expansion, and fluctuation of real income. The empirical evidence suggests that the relative importance of monetary changes in determining domestic price changes declines over time as the degree of openness of the economy rises over time.     

Budget consolidation in a small open economy: a case study for Slovenia

In this article, we use the macroeconometric model SLOPOL10 to calculate simulations of the development of the Slovenian economy until 2030. Starting from the present favourable prospects of the European economies, the forecast is very optimistic but it can nevertheless be improved by optimal fiscal policies as calculated using the OPTCON2 algorithm. If a negative shock to world trade of a size comparable to the Great Recession occurs, it will entail a decline in GDP and a slow recovery. In this case, optimal fiscal policies should not act in an expansionary way as the effectiveness of fiscal policy with respect to output and employment is rather limited in a small open economy like Slovenia. Instead, the goal of budget consolidation will call for a more restrictive fiscal policy, at least if the shock is temporary.
