Some Further Evidence on Exchange-Rate Volatility and Exports

The relationship between exchange-rate volatility and aggregate export volumes is examined using a model that includes real export earnings of oil-exporting economies as a determinant of export volumes of a sample of 12 industrial countries. Four fixed-coefficient panel-data estimation techniques, including a generalized method of moments (GMM) and random coefficient (RC) estimation, are employed on panel data covering the estimation period 1977:1–2003:4 using three measures of exchange-rate volatility. Our aim is to provide a theoretically and empirically justifiable specification that can guide researchers. In contrast to recent studies employing panel data, we find little evidence that volatility has a negative and significant impact on trade. We use second-generation RC estimation, which corrects for biases arising from incorrect functional forms, omitted variables, and measurement errors. Our results suggest that the finding of a significant and negative impact of volatility is attributable to specification biases. JEL no. C23, F3, F31     

Real exchange-rate uncertainty and US foreign direct investment: an empirical analysis

This paper empirically analyzes the impact of exchange-rate uncertainty, exchange-rate movements, and expectations on foreign direct investment (FDI). Using data on US outward FDI for the period 1984–2004 we examine two competing measures of exchange-rate volatility. While the standard measure yields a discouraging effect on FDI outflows in all industries the alternative risk specification reveals a clear distinction between manufacturing and non-manufacturing industries, with the latter showing a positive correlation with increased exchange risk. A real appreciation of host-country currency was associated with higher FDI flows, while expectations about an appreciation showed a negative result.     

ON MEASURING THE EFFECT OF INFLATION UNCERTAINTY ON REAL GNP GROWTH

In this paper we re-examine the relationship between inflationuncertainty and total output. To properly specify an estimatingequation, we investigate the time series properties of two frequentlyused measures of inflation uncertainty. We fail to reject thehypothysis that each series has a unit root. However, the uncertaintymeasures are not cointegrated with output and relative oil prices.This means that the proper specification is in terms of differences.With this specification we find that an increase in inflationuncertainty growth reduces real GNP growth but, unlike earlierwork, we find that this effect is temporary. It is also unlikelythat an inflation uncertainty shock on its own could producea recession.     

Explaining Heterogeneity in the Effect of the Exchange Rate and Exchange Rate Volatility on Foreign Direct Investment: A Meta‐Analysis Approach

This study examines the effect of exchange rate and exchange rate volatility on foreign direct investment (FDI) by using a meta‐analysis. We filter out publication bias within the 1,329 estimates, pooled from 101 studies and employ Bayesian Model Averaging to reduce model uncertainty and explain the existing heterogeneity. The results reveal that the exchange rate system, estimation characteristics, and the modeling approach have an important and noticeable influence on the statistical significance and direction of the estimates. On one hand, the impact of exchange rate volatility is relatively lower in countries with higher trade openness, human capital and better protection of intellectual property rights. On the other hand, greater geographical distance and technology gap between the host and the home economy are associated with greater uncertainty and thus accentuate the negative causality between exchange rate volatility and FDI. Such sensitivities suggest that greater emphasis should be placed on reporting estimates of the impact of the exchange rate and its volatility on FDI across a variety of methodological characteristics and specification and estimation choices.     

Sectoral labor employment in a Caribbean economy: The case of Barbados

This study examines the demand for labor in five major sectors of the Caribbean economy of Barbados. While the demand for labor function in the nontradable sectors appears well-defined in terms of real wages and real aggregate output, the inclusion of a variable to capture the effects of capital-deepening appears important to the specification of labor demand in the tradable sectors—agriculture and manufacturing. Low estimates of real wage elasticities and real output elasticities in the vicinity of unity suggest that employers in the major sectors are more likely to alter their demand for labor based on expectations of the economy’s performance than in response to labor cost factors denominated in producer prices.     

Estimation of the probability of labor force participation of the AFDC population-at-risk

Summary In summary, the functional form makes quite a difference. An investigator should be quite wary of making generalizations based on any single specification or estimation technique. However, the above results have shown in striking fashion the superiority of MLE of the sigmoid specifications over the OLS estimation of the linear probability specification. Although the logistic or urban specification require iterative solution, this is no barrier on a modern digital computer, with appropriate special algorithms. A further advantage of the MLE is the asymptotic normality of the estimates of _i which permits large sample interval estimation, and the iteration method of scoring employed yields directly an estimate of the standard deviation of each normally distributed _i . Also standard tests of significance are now applicable.Perhaps most importantly, the sigmoid specifications are consistent with a probability interpretation since the estimates lie inside the unit interval, and the sigmoid shape is consistent with the assumed unimodal distribution of the participation decision.In conclusion, results reported in previous investigations of the probability of labor force participation or labor force participation rate which have relied on the least squares estimation of a linear probability specification are likely to be unreliable as to he magnitude of the response attributed to changes in explanatory variables.     

MACROECONOMIC UNCERTAINTY AND AGGREGATE PRIVATE INVESTMENT IN SOUTH AFRICA

This paper investigates the effects of time varying uncertainty on aggregate private fixed investment in South Africa. The GARCH generated measures of volatility of selected macroeconomic variables indicating five measures of uncertainty are used in the analysis. These are output growth uncertainty, uncertainty about changes in the real effective exchange rate, uncertainty about changes in the real interest rate, producer inflation uncertainty, and terms of trade uncertainty. The results of the estimation by an empirical ECM model of conventional investment determinants controlling for the effects of uncertainty indicated that, over all, time varying macroeconomic uncertainty significantly reduces private fixed investment.     

The Impact of Inflation Uncertainty on Output Growth and Inflation in Thailand*

We explore the impact of inflation uncertainty on output growth in Thailand, an emerging market economy with moderate inflation. Inflation and output uncertainty are modeled in a bivariate constant conditional correlation generalized autoregressive conditional heteroskedastic (AR(p)‐cccGARCH(1,1)) specification. We include the exchange rate in the mean equations, and use the headline and core inflation rates and industrial production to generate inflation and output uncertainty series. These series are then used in Granger causality tests to make inferences about the effect of monetary policy‐induced inflation uncertainty. Causality tests show a positive relation from inflation to inflation uncertainty. Additionally, increased inflation uncertainty decreases output. These results are consistent with real costs associated with moderate inflation. Finally, we find no evidence that monetary policy reduced these costs.     

Economic policy uncertainty and firms' investment and financing decisions in China

This paper designs a quasi-natural experiment for the identification of causal relationships between economic policy uncertainty and firms' investment-financing decisions using China's supply-side structural reform in 2015. We construct measures of asset reversibility across industries using China's national input–output flow table and match them with nonfinancial firms listed in China's A-share stock market from 2013 to 2017. We then use the difference-in-difference estimation strategy to investigate two-dimensional variations in periods (i.e., before and after 2015) and asset reversibility (i.e., high- and low-reversibility industries). The empirical results show that economic policy uncertainty significantly impedes real investment and reduces net debt issuance for private firms, whereas no such effects exist in state-owned firms. Interestingly, however, economic policy uncertainty has no significant impact on firms' cash-holding decisions.     

The causes and impact of the african debt crisis

This article examines the African debt crisis. It focuses on factors leading to the accumulation of the debts and their impact on the debtor nations. The significance of the study lies in the fact that the African debt burden presents a gruesome picture of hopelessness. This is reflected by the continent’s massive debt of $230 billion, equivalent to almost three times the continent’s annual export earnings. This is expected to jump to $550 billion by the year 2000. Africa’s crushing debt burden has become one of the most important factors constraining recovery and development. As the United Nations Children’s Fund estimates, one thousand people die each day in Africa because of the debt crisis. The analysis shows that due to the multifaceted nature of the causes of the debt crisis, both creditors and debtors should agree on the options for dealing with the crisis. It further shows that there is the urgency for Africa to tackle its numerous sociopolitico-economic problems. Africa can make real economic progress only when it begins to get on top of its debt crisis.     

Uncertainty and monetary policy

The experience of monetary policy making in an uncertain environmenthas encouraged increased attention to the concept of model uncertainty,that is, uncertainty as to which is the best model. A particulardifficulty has been the need to operationalise the concept inorder to yield definitive policy recommendations. If this typeof uncertainty is unquantifiable, then a policy rule determinedby a single model may not in fact be the best approach; pluralismof method and the exercise of judgement offer a potential solution.A rigorous foundation for such an approach is available in Keynes'sphilosophical analysis of decision making under uncertainty.It is concluded that more analytical attention needs to be devotedto agents’ own model uncertainty, and to judgement. Butultimately the scope for synthesis between the model uncertaintyand Keynes uncertainty approaches rests on whether or not thesubject matter is such that knowledge of it is best representedby one formal model.     

How to Share Our Risks Efficiently? Principles for Optimal Social Insurance and Pension Provision

The efficient organisation of social insurance is an important problem for modern societies. The paper discusses evidence that shocks in labour income have largely persistent effects and analyses the implications of this observation for the optimal design of institutions for wage contracting, social security, and pensions. In an optimal contract, wages reflect variations in individual productivity for incentives reasons. However, the optimal contract insures workers against firm specific shocks. These can better be born by shareholders who can diversify risks on capital markets. Progressive income taxation provides further insurance. On top of that there is scope for additional insurance based on ‘verifiable’ information on unemployment and health conditions. As final form of ‘insurance’, the paper analyzes the role of self-insurance. Income shocks can be absorbed partially by precautionary saving. The individual’s saving plans for retirement and for precaution are, therefore, related issues. In an institutional setting with mandatory saving for retirement, an integration of disability and unemployment insurance on the one hand and the pension system on the other hand in a lifetime savings account allows for this interrelation. The paper analyzes how to deal with the uncertainty in the return on savings in the framework of a lifetime saving account.     

The Impact of US Uncertainty Shocks on Small Open Economies

In this paper, we investigate the impact of US uncertainty shocks on GDP growth in nine small open economies: Australia, Canada, Denmark, Finland, Iceland, New Zealand, Norway, Sweden and the United Kingdom. We compare the impact of two types of shocks: i) stock market volatility shocks and ii) policy uncertainty shocks. Using quarterly data from 1986Q1 to 2016Q1, this issue is analysed using Bayesian VAR models. Our results suggest that policy uncertainty seems to matter more than stock market volatility. Stock market volatility shocks appear to robustly have significant effects on Danish GDP growth. Policy uncertainty shocks, on the other hand, reliably lowers GDP growth in all five Nordic countries in a statistically significant manner. Statistically significant effects of policy uncertainty shocks on the Anglo-Saxon countries in our sample are harder to establish and are, in our preferred specification, only found for the United Kingdom.

Examining the Robustness of the Inflation and Growth Relationship

Using Bayesian Model Averaging, we examine whether inflation's effects on economic growth are robust to model uncertainty across numerous specifications. Cross-sectional data provide little evidence of a robust inflation-growth relationship, even after allowing for non-linear effects. Panel data with fixed effects suggest inflation is one of the more robust variables affecting growth, and non-linear results suggest that high inflation observations drive the results. However, this robustness is lost when estimation is carried out with instrumental variables.     

Capturing Regional Trade Effects in the Presence of Other Trade Effects: The Impact of the Europe Agreement on Poland’s Imports

This paper investigates the impact of the Europe Agreement on Poland’s imports using econometric models applied to highly disaggregated trade data. This allows other influences on Poland’s trade patterns to be controlled for, specifically the effects of other trade agreements and for the emergence of China. The paper shows that the Europe Agreement had transitory effects on Poland’s imports, but that the scale of the trade effects and the balance of trade creation and diversion effects is sensitive to model specification. The preferred dynamic specification which allows for heterogeneity of time effects across sectors identifies the Europe Agreement to have net trade-creating effects.      

Age and Productivity: Sector Differences

In most industrialised countries, the workforce is ageing rapidly. If ageing workforces affect sectors differently, the total impact of ageing will depend on the industrial structure of an economy. This paper measures the impact of changes in the age structure of establishments on productivity using representative linked employer–employee panel data. We argue that establishment age-productivity profiles might differ for various reasons. For example, the importance of physical strength and possibilities to compensate deficits in skills differ between sectors. We investigate differences in the age-productivity profiles between the (metal) manufacturing and services sectors. However, in our preferred specification that controls for several potential sources of estimation biases, we find no significant differences in the age-productivity profiles between these sectors.

The Output Effects of Money Growth Uncertainty: Evidence from a Multivariate GARCH-in-Mean VAR

In this paper we extend the work in Serletis and Shahmoradi (Macroecon Dyn 10:652–666, 2006) by investigating the effects of money growth uncertainty on real economic activity, in the context of a multivariate framework in which a structural vector autoregression is modified to accommodate multivariate GARCH-in-Mean errors, as in Elder (J Money, Credit Bank 36:912–928, 2004). The model uses a recursive identification scheme, takes into account the possible interaction between conditional means and variances, isolates the effects of money growth volatility on output growth, and is able to explicitly model heteroskedasticity. We use quarterly data for the United States over the period from 1959:1 to 2005:4, provide a comparison among simple-sum, Divisia, and currency equivalent monetary aggregation procedures at each of the four levels of monetary aggregation—M1, M2, M3, and MZM—and find evidence that money growth volatility has significant negative effects on output growth. Issues of structural stability are addressed and sub-sample analysis is performed. Moreover, the robustness of the results to alternative identification schemes, alternative measures of the level of economic activity, and to the use of monthly observations is also investigated.     

Real wages,investment and employment: New evidence from West German sectoral data

Real Wages, Investment and Employment: New Evidence from West German Sectoral Data. — Non-separable capital adjustment costs imply that investment directly affects the demand for labour and therefore justify not only the lagged dependent variable but also the presence of investment expenditures or Tobin’s valuation ratio Q in labour demand estimation. On this basis, the authors estimate a very parsimonious specification of demand for blue-collar workers in a panel of 32 West German industries. They find much larger short-run real wage employment elasticities than previous research, and robustly significant positive effects of investment or Tobin’s Q on labour demand.
