Does exchange-rate volatility depress export flows: The case of LDCs

In the area of international trade, few studies have examined whether increases in exchange-rate volatility depress trade flows of LDCs. The aim of this paper is to investigate empirically the impact of exchange-rate volatility on the export flows of 10 developing countries over the quarterly period 1973–98. The econometric analysis exploits the theory of cointegration, given the obvious nonstationarity of the data. Estimates of the cointegrating relations are obtained using Johansen's multivariate procedure. Evidence of stability of the cointegrating space is examined using Hansen's [1992a] tests. Short-run dynamic modelling is accomplished using the error-correction technique, and the stability test results are obtained using Hansen [1992b] tests. In conformity with theoretical considerations, the results indicate that increases in the exchange-rate volatility exert a significant negative effect upon export demand in both the short-run and the long-run in most of the countries studied. These effects may result in significant reallocation of resources by market participants.     

The long-run relationship between stock return dispersion and output

Based on the rational that some industry groups are more closely linked to the business cycle than others, we re-examined a previous analysis on the long-term relationship between stock return dispersion by industry and Gross Domestic Product (GDP), which evaluated data until 1987 by extending it to 2008. Using Mean Square Forecast Errors (MSFE) statistics, we find that incorporating the return dispersion in Vector Autoregressive (VAR) models enhances their forecasting power for output (GDP) in the long run. This article also determines that the relationship between stock return dispersion by industry and GDP is tenuous in the recent decade from 1999.     

The impact of institutional volatility on financial volatility in transition economies

What have been the determinants of financial volatility in the transition countries of Central and Eastern Europe and the former Soviet Union? This paper posits that institutional changes, and in particular the volatility of crucial institutions such as property rights, have been the major causes of financial volatility in transition. Building a unique monthly database of 20 transition economies from 1991 to 2017, this paper applies the GARCH family of models to examine financial volatility as a function of institutional volatility. The results show that more advanced institutions help to dampen financial sector volatility, while institutional volatility feeds through directly to financial sector volatility in transition. Democratic changes in particular engender much higher levels of volatility, while property rights are sensitive to the metric used for their measurement.     

The role of the political cycle in the relationship between economic policy uncertainty and the long-run volatility of industry-level stock returns in the United States

In this study, we investigate how US economic policy uncertainty (EPU) drives the long-run components of volatilities in industry-level stock markets. We use a modified specification of GARCH-MIDAS and find that EPU increases the long-run volatility of the industrials and materials industries and decreases it in 4 of the 10 industries considered here: consumer staples, healthcare, information technology and materials. In addition, we add a dummy variable for the political cycle (PLC) to study whether the relationship between EPU and the volatility of industry returns is significantly different under different political regimes. The results imply that a Republican presidency dampens the effects of EPU on the long-run volatility of the consumer staples, healthcare and information technology industries. We also decompose the aggregated EPU into 11 category-specific EPUs to explore the detailed relationship between category-specific EPU and long-run volatility driven by aggregate EPU. The results for the category-specific EPU are consistent with the findings for the aggregate EPU. In particular, the weakened effect of PLC on the relationship between EPU and the long-run volatility of industry-level returns is also confirmed by MIDAS regression with beta weight scheme.     

Distance in time between transition economies and the European Union

The time distance methodology used offers a new perspective to the problem, an additional statistical measure, and a presentation tool for policy analysis and debate readily understood by policy makers, media and general public. Disparity between the analysed transition economies and EU countries is considerably smaller for other indicators than for GDP per capita. Compared with Ireland, Portugal and Greece Slovenia was in 1995 in 13 cases behind (but time lag of Slovenia never exceeded 10 years) and in 13 cases ahead of them. Sicherl (1997a) discusses application of S-distance to time series regressions, models, forecasting and monitoring. First version received: October 1995/final version received: April 1998     

Price and volatility dynamics between securitized real estate spot and futures markets

This study is among the first to examine the price, volatility and covariance dynamics between securitized real estate spot and futures markets. It provides a distinctive and yet complementary perspective on the predictability of real estate spot return and spot volatility based on the information from the spot market alone. The results show that for the EPRA/NAREIT Europe index, the spot market tends to lead its futures market in the long run during the sample period, which can be attributed to a rather illiquid real estate futures market in sharp contrast with a voluminous spot market. Furthermore, we find the V-shaped asymmetric effect of the basis on the futures market volatility, which represents the primary channel of strong volatility transmission between securitized real estate spot and futures markets during the whole sample and the post-crisis period. This sheds light on the hedging effectiveness for the REIT index.     

Correct cointegration tests of the long-run relationship between nominal interest and inflation

The Fisher (1930) hypothesis suggests that a long-run equilibrium relationship exists between the non-stationary series: nominal interest and expected inflation. Testing such a cointegrating relationship is complicated by the presence of the unobserved ex antereal rate of interest in residuals from the cointegrating regression. Assumptions concerning the stochastic properties of the expected real rate of interest are examined, and two proxies for the ex antereal rate are employed in multivariate cointegration tests of the Fisher hypothesis.     

Determinants of capital flows to emerging and advanced economies between 1990 and 2011

The previous and latest crises confirmed that stability of external financing of the economy is determined not only by the volume of capital inflow but also by its structure. It is established that a bias in gross external liabilities towards debt, especially short-term, may rise vulnerability to financial crises. Greater share of equity capital, mainly direct investment is not found to bear such financial risk. The results of Bayesian Model Averaging (BMA) show that influence of variables inherent in macroeconomic and portfolio approaches varies depending on the type of capital inflow and the group of countries. We also find some arguments that equity investment is a more desirable form of foreign capital because debt inflows are more responsive to global factors and therefore more volatile. As a word of caution, we highlight the need for diversification and careful monitoring of external financing sources and forms.     

A percolation model of eco-innovation diffusion: The relationship between diffusion, learning economies and subsidies

An obstacle to the widespread adoption of environmentally friendly energy technologies such as stationary and mobile fuel cells is their high upfront costs. While much lower prices seem to be attainable in the future due to learning curve cost reductions that increase rapidly with the scale of diffusion of the technology, there is a chicken and egg problem, even when some consumers may be willing to pay more for green technologies. Drawing on recent percolation models of diffusion, we develop a network model of new technology diffusion that combines contagion among consumers with heterogeneity of agent characteristics. Agents adopt when the price falls below their random reservation price drawn from a lognormal distribution, but only when one of their neighbors has already adopted. Combining with a learning curve for the price as a function of the cumulative number of adopters, this may lead to delayed adoption for a certain range of initial conditions. Using agent-based simulations we explore when a limited subsidy policy can trigger diffusion that would otherwise not happen. The introduction of a subsidy policy seems to be highly effective for a given high initial price level only for learning economies in a certain range. Outside this range, the diffusion of a new technology either never takes off despite the subsidies, or the subsidies are unnecessary. Perhaps not coincidentally, this range seems to correspond to the values observed for many successful innovations.     

The ERM and monetary integration in the European Union: an investigation of long-run relationships

This paper investigates the integration of EU money supplies for the ERM period 1979Q1-93Q4. An estimating equation is derived from a simple equilibrium model of the EU money markets. Estimation is undertaken using the Johansen maximum likelihood cointegration procedure. The results show that those EU members with relatively low exchange rate premia against the DM are those whose variations in the money supply have been most sensitive to those of Germany.     

Nominal and real volatility as determinants of FDI

This article examines the role of country-specific sources of output and interest rate or exchange rate volatility in driving Foreign Direct Investment (FDI) activities. Building on a dataset with bilateral FDI flows among 24 Organization for Economic Co-operation and Development (OECD) economies over the period 1985–2007, we find that nominal and real volatility strongly deter foreign investments. Output and exchange rate volatility matter in particular for the decision whether to invest in a foreign country in the first place. Interest rate volatility mainly influences the amount of foreign investments.     

The long-run convergence of exchange rates and prices in the European Union

This paper provides tests of Purchasing Power Parity (PPP) for members of the EU-27 not in the euro area, using multivariate and panel cointegration techniques, for the period since the introduction of the euro currency in 1999 until the end of 2009. The results indicate that long-run PPP holds in ten cases and that domestic prices or the nominal exchange rate is the main driver of the short-run adjustment to stationarity. These results are discussed in terms of monetary convergence in the long-run.     

A simultaneous analysis of exchange-rate passthrough into prices of imperfectly substitutable domestic and import goods

For the most part, the relationship between import and domestic prices, and their common linkages to currency movements, has been ignored, especially at the industry level. This paper examines the direct and indirect impacts of exchange rates on prices, analyzing a panel of 26 4-digit SIC industries over the 1978–1987 period. The results are consistent with the view that the indirect influence of exchange rates on domestic prices through import competition clearly dominates any direct impact, and that import prices are motivated largely by pricing-to-market. We find some evidence of a limiting effect of market concentration on passthrough into both domestic and import prices, while an increased reliance on imported inputs and increased substitutability between domestic and foreign goods each enhances the passthrough into domestic prices.     

Asymmetric volatility spillovers between the U.K. regional worker flows and vacancies

This article investigates volatility spillovers between the U.K. regional job finding, job separation and vacancy rates. Employing a large Bayesian logistic smooth transition vector autoregression model, we find high volatility spillovers between the U.K. regional labour markets. Analyses of net spillovers show that, in general, shocks to job separation rates tend to spread into job finding and vacancy rates, while vacancy rates are usually at the receiving end of shocks transmitted from the job separations and job findings. To shed further light on the shock propagation mechanism, we also look into more detailed matters such as the differences in spillovers between regions within the same regime, and that of the same region but in different regimes.     

The long-run causal relationship between transport energy consumption and GDP: Evidence from heterogeneous panel methods robust to cross-sectional dependence

This paper employs panel methods that address/mitigate heterogeneity and cross-sectional dependence to determine the direction and sign of long-run causality between transport energy consumption per capita and real GDP per capita. Granger-causality was determined to run from GDP to energy.     

The real effect of currency misalignment on productivity growth: evidence from middle-income economies

There have been interesting perspectives on the role of real currency misalignment in productivity growth. Whereas some studies warn against the destructive effect of real currency misalignment on productivity growth, others simply encourage it, at least, in the form of undervaluation. This paper documents evidence in support of the latter argument for 100 middle-income countries for the 1994–2010 period, using fixed-effects and generalized method of moments estimation techniques. The paper finds real currency misalignment to enhance productivity growth if it occurs as undervaluation; and to hamper productivity growth if it occurs as overvaluation. The paper also finds the impact of real currency misalignment on productivity growth to be symmetric, implying that the size of the impact is independent of the size of the misalignment. Moreover, the choice of the real misalignment measure may matter.     

The experience of some OECD economies on tax smoothing

Observed random walk behaviour of a tax rate does not necessarily support the tax smoothing hypothesis though the latter implies the former. This article presents a direct test of tax smoothing by showing that if the tax smoothing hypothesis holds then the future tax rate should cointegrate with the current permanent government expenditure rate even though the tax rate is a random walk. This test is a direct and robust test of a number of ‘random walk models’ available in the literature. This procedure also enables us to differentiate among ‘strong tax smoothing’, ‘weak tax smoothing’ and ‘no-tax smoothing’, all of which are consistent with the random walk behaviour of a tax rate. Application of this test to Australia, Canada, Italy, Japan, the Netherlands, New Zealand, the UK and the US show evidence in support of weak forms of tax smoothing.     

Commercial banks and real estate lending: The Texas experience

This paper examines the performance of Texas commercial banks specializing in mortgage lending during the difficult times of the late 1980s and early 1990s to investigate how representative their experience as compared with that of banks concentrating in real estate lending across the country. The results show that Texas REBs performed very poorly during the 1980s and early 1990s, but this was because the Texas REBs were clearly different from the majority of the banks classified as REBs in the rest of the country. In contract to non-Texas real estate specializing banks, those in Texas banks put substantial assets into much riskier construction and development loans, and in loans on commercial property, such as office buildings, hotels and shopping centers. In a poor real estate market, these loans performed very poorly. The analysis indicates that the Texas experience is not a basis for rejecting the view that the commercial bank industry can safely replace the declining thrift industry as a major source of residential mortgage financing.
