Dynamic effects of government policies in an open economy

The effects of three government policies, an increase in the provision of government services, an open market operation, and an increase in the rate of growth of government liabilities, are studied in a long-run model of a small open economy with flexible exchange rates. The government budget constraint, the degree to which government bonds are net wealth to the public, and the degree of substitutability of government services for private market purchases are all considered. The determination of the exchange rate and the adjustment of the accounts of the balance of payments to changes in government policy are explored.

Structural change in an open economy

We study the importance of international trade in structural change. Our framework has both productivity and trade cost shocks, and allows for non-unitary income and substitution elasticities. We calibrate our model to investigate South Korea's structural change between 1971 and 2005. We find that the shock processes, propagated through the model's two main transmission mechanisms, non-homothetic preferences and the open economy, explain virtually all of the evolution of agriculture and services labor shares, and the rising part of the hump-shape in manufacturing. Counterfactual exercises show that the role of the open economy is quantitatively important for explaining South Korea's structural change.     

Inflationary finance in an open economy

Models of inflationary finance that consider trade and capital flows generally conclude that openness curtails the ability of governments to impose the inflation tax due to currency substitution. This paper models two channels that allow central banks to increase inflation tax revenue by opening the economy. First, central banks can open the capital account subject to a reserve requirement on capital inflows. Revenue maximization produces a smaller reserve requirement on foreign capital inflows that on domestic deposits. Second, central banks can impose prior import deposits to broaden the monetary base in order to use the inflation tax on imports as an alternative to tariff revenue.     

The effects of asymmetric information between borrowers and lenders in an open economy

This paper assesses the effects of asymmetric information between borrowers and lenders in an open economy with access to international capital markets. Information asymmetry and agency costs arise because only borrowers can costlessly observe actual returns from production. Agency costs increase the cost of external finance and lower steady state investment, capital and output. They also affect the business cycle and the central bank’s response to shocks. The long-run effects of agency costs are exacerbated in an open economy and their impact is influenced by the degree of access to international capital markets. The results thus highlight the importance of incorporating credit market interactions into open economy macroeconomic models.     

A macroeconomic model with asset equilibrium for an open economy

This article is concerned with the problem of the effects of monetary policy in an open economy in the long run. In order to analyze this problem under assumptions that are more suitable for long-run analysis than those of the usual IS-LM model a new model has been constructed with flexible prices, fixed exchange rates and a flexible capital stock. Within this framework it is found that the effectiveness of monetary policy crucially depends upon the degree of asset and goods arbitrage across national borders. Sufficient asset or goods arbitrage are both sufficient conditions to yield a zero effect of monetary policy except on foreign exchange reserves.     

Bond finance,bank credit,and aggregate fluctuations in an open economy

Corporate sectors in emerging markets have noticeably increased their reliance on foreign financing, presumably reflecting low global interest rates. The evidence also shows a rebalancing from bank loans towards bonds. To study these developments, we develop a dynamic open economy model where these modes of finance are determined endogenously. The model replicates the stylized facts following a drop in world interest rates; in particular, rebalancing towards bonds occurs because bank credit becomes relatively more expensive, reflecting the scarcity of bank equity. More generally, the model is suitable for studying interactions between modes of finance and the macroeconomy.     

Credit crunch in a small open economy

We construct an open-economy DSGE model with a banking sector to analyze the impact of the recent credit crunch on a small open economy. In our model the banking sector operates under monopolistic competition, collects deposits and grants collateralized loans. Collateral effects amplify monetary policy actions, interest rate stickiness dampens the transmission of interest rates, and financial shocks generate non-negligible real and nominal effects. As an application we estimate the model for Poland-a typical small open economy. According to the results, financial shocks had a substantial, though not overwhelming, impact on the Polish economy during the 2008/09 crisis, lowering GDP by approximately 1.5 percent.     

An examination of order effects in auditors' inherent risk assessments

While recency effects have been reported in a variety of audit tasks, recent studies suggest that these effects may be mitigated under certain conditions. The importance of investigating order effects in auditors' judgments rests with its potential to impact on the efficiency and effectiveness of audits. Since current studies suggest that recency effects may not impact on all audit situations, it is necessary to identify conditions or variables in the task environment that either induce or mitigate recency.
This study examines the occurrence of order effects in auditors' inherent risk assessments, a task not previously examined. Using a case study administered to 70 auditors, this study found that auditors' judgments were not influenced by the order in which audit evidence was evaluated. Rather, the results suggest that judgments of inherent risk may be biased towards conservatism. This may not be surprising given the negative consequences associated with failing to adequately plan an audit. This may cause auditors to act cautiously and thus mitigate recency effects.     

International day-of-the-week effects: An empirical examination of iShares

Ample evidence suggests that day-of-the-week patterns exist in US and foreign equity returns. We extend the evidence on the day-of-the-week effect in equity returns by examining the return patterns of iShares for 17 countries and Standard and Poor's Depository Receipts (SPDRs) to establish whether previously observed predictabilities in equity returns are reflected in iShares' returns. We utilize a split sample to examine return patterns and develop trading rules using the initial subsample. We then test those trading rules out of sample. Empirical results reveal that iShares exhibit day-of-the-week return patterns that can be exploited by informed traders.     

A model of medium term exchange rate forecast in an open economy The case of the mexican peso

Keynes (1930) and Samuelson (1965) proposals open the possibility of matching predictability and efficiency, as evidenced by the seminal study by Fisher (1930). Recent findings suggest that the foreign exchange market gradually incorporates relevant information allowing the formation of prices in a rational manner but not randomly. Models of exchange rate by term based on asset valuation suggest that the inclusion of risk in the spot rate increases the degree of predictability. The results show that after incorporating an accurate measure of risk, predictability of medium term foreign exchange rate increases.     

Determination of inflation in an open economy Phillips curve framework: the case of developed and developing Asian countries

This paper investigates the determination of inflation in the framework of an open economy forward-looking as well as conventional backward-looking Phillips curve for eight Asian countries – Japan, Hong Kong, Korea, Singapore, Philippines, Thailand, China Mainland and India. Using quarterly data from the 1990s to 2005 and applying the instrumental variables estimation technique, we find that the output gap is significant in explaining the inflation rate in almost all the countries. Furthermore, at least one measure of international competitiveness has a statistically significant influence on inflation in all the countries. The differences in the developed and developing world are highlighted by the significance of agriculture related supply shocks in determining inflation in the case of developing countries. For all countries, the forward-looking Phillips curve provides a better fit compared to the backward-looking variant.     

Optimal wage re-negotiation in a closed and open economy

This paper investigates an economy in which there are short-term wage contracts that are re-negotiated under certain conditions. The paper determines the optimal frequency of wage re-negotiation and shows that it depends positively on measures of aggregate variability and Phillips curve slope. The role of optimal wage re-negotiation is to mitigate the output effects of various shocks. In the context of an open economy, it is shown that the desirable exchange rate regime in an economy with optimal wage re-negotiation depends on the stochastic structure of the economy.     

Robust effects of a debt-financed tax cut in an economy with incomplete markets

Price,output, and exchange rate movements in the open economy

Since the advent of managed floating it has come to be accepted as a stylized fact that short-run deviations from purchasing power parity are both substantial and persistent. Two explanations of these deviations have been advanced in the literature. One emphasizes the role of changes in non-traded goods prices while the other views deviations from purchasing power parity as being due to sticky goods prices and slow adjustment of goods markets. This paper presents yet a third possible explanation of deviations from purchasing power parity — they may be necessary in order to facilitate the relative price changes that are required to maintain equilibrium in the face of unanticipated shocks. In addition, the issue of exchange rate overshooting is addressed. Whereas the sticky price models view exchange rate overshooting and exchange rate volatility as symptoms of some fundamental disequilibrium, the perspective taken here is that these events are, in principle, compatible with a world in which all markets clear continuously.     

An examination of market efficiency: Information order effects in a laboratory market

A series of laboratory double auction experiments is conducted to examine whether the order of information releases affects market prices. Behavioral research on belief revision has shown that individuals are influenced by the order in which a series of information items is presented. The experiments are designed to provide a controlled investigation of whether order effects as displayed by individuals also can influence prices in a market setting where outcomes are not a simple aggregation of individual behavior. Significant evidence is found of a recency effect in the experimental asset markets.     

Revisiting the supply side effects of government spending

We revisit the macroeconomic effects of government consumption in the neoclassical growth model when agents face uninsured idiosyncratic investment risk. Under complete markets, a permanent increase in government consumption has no long-run effect on interest rates and capital intensity, while it increases work hours due to the negative wealth effect. These results are upset once we allow for incomplete markets. The same negative wealth effect now causes a reduction in risk taking and the demand for investment. This leads to a lower risk-free rate and, under certain conditions, also to a lower capital-labor ratio and lower productivity.     

Rational expectations and the effects of government debt

This paper incorporates the effects of government debt into a standard rational expectations macroeconomic model. Due to limited current information, even when the most extreme propositions about fiscal neutrality are true, there are output and interest rate effects of unanticipated changes in government debt. Therefore the observation of a positive correlation between government deficits and output or interest rates does not imply that government bonds are net wealth.
