The transmission of foreign shocks to South Eastern European economies: A Bayesian VAR approach

The paper analyses the macroeconomic effects of foreign shocks in three South-East European (SEE) economies: Croatia, Macedonia and Bulgaria. In this regard, we investigate the transmission of several eurozone shocks (output gap, money market rates and inflation) on various macroeconomic variables in the aforementioned countries (output, inflation, money market rates and budget deficits). We trace the effects of foreign shocks on the basis of impulse response functions obtained from the Bayesian Vector Auto Regressions (VARs) separately for each country. The main findings from our study are: first, economic expansion in the eurozone has strong output and inflation effects on SEE economies, implying some degree of synchronization of business cycles; second, eurozone inflation is instantly and to a great extent transmitted to domestic inflation, suggesting that inflation in the SEE economies is mostly driven by foreign inflation; third, domestic money market rates are not closely linked with eurozone money markets; fourth, monetary policy in the SEE countries does not seem to be responsive to eurozone inflation shocks; and fifth, the fiscal authorities attempt to offset the spillover effects from both economic expansion and monetary tightening in the eurozone.     

Short-term spot rate models with nonparametric deterministic drift

Most studies assume stationarity when testing continuous-time interest-rate models. However, consistent with Bierens [Bierens, H. (1997). Testing the unit root with drift hypothesis against nonlinear trend stationary, with an application to the US price level and interest rate. Journal of Econometrics, 81, 29–64; Bierens, H. (2000). Nonparametric nonlinear co-trending analysis, with an application to interest and inflation in the United States. Journal of Business and Economics Statistics, 18, 323–337], our nonparametric test results support nonlinear trend stationarity. To accommodate nonstationarity, we detrend the interest-rate series and re-examine a variety of continuous-time models. The goodness-of-fit improves significantly for those models with drift-induced mean reversion and worsens for those with high volatility elasticity. The inclusion of a nonparametric trend component in the drift significantly reduces the level effect on the interest-rate volatility. These results suggest that the misspecification of the constant elasticity model should be attributed to the nonlinear trend component of the short-term interest-rate process.     

Do fixed income mutual fund managers have managerial skills?

Motivated by Berk and Green [Berk, J., & Green, R. (2004). Mutual fund flows and performance in rational markets. Journal of Political Economy, 112, 1269–1295] and Chevalier and Ellison [Chevalier, J., & Ellison, G. (1999). Career concerns of mutual fund managers. Quarterly Journal of Economics, 114, 389–432] who show theoretically that performance persistence may be short-lived, we complement Bollen and Busse [Bollen, N., & Busse, J. A. (2004). Short-term persistence in mutual fund performance. Review of Financial Studies, 18, 569–597] and examine performance persistence in high-quality corporate-bond mutual funds over short horizons. Empirically, we find supporting evidence of performance persistence over shorter horizons. Our empirical tests also suggest that the performance persistence we document may be at least partly due to managerial skills.     

Interest rate movements and US consumers’ inflation forecast errors: is there a link?

The Fisher effect maintains that movements in short-term interest rates largely reflect changes in expected inflation. Since expected inflation is subject to error, we ask whether interest rates move in response to over- and under-predictions of inflation. In answering, we measure expected inflation by the consumers’ forecast of inflation derived from the Michigan Surveys of Consumers (MSC). Our findings for 1978–2013 indicate that the MSC inflation forecasts were unbiased, efficient, and directionally accurate. For 1978–2007, (i) interest rates moved downward (upward) in response to MSC over-predictions (under-predictions) of inflation, and (ii) MSC inflation forecast errors had directional predictability for interest rates. However, no link between interest rate movements and MSC inflation forecast errors is detected for 2008–2013 when monetary policy kept short-term interest rates unusually low.     

Why big fiscal deficits and low inflation can coexist

• ▀ The surge in government debt caused by ballooning fiscal deficits is a necessary response to the coronavirus crisis. But we doubt this will lead to a burst of inflation in the advanced economies (AEs), let alone a debt crisis.
• ▀ Our fiscal forecasts assume AEs’ budget deficits averaged 20% of GDP or so in Q2. However, our deficit forecasts point to a sharp narrowing thereafter and for public debt as a share of GDP to peak in 2021.
• ▀ The risks around this forecast skew firmly towards deficits remaining wide, reflecting the balance of risks around our GDP forecasts and the possibility that governments allow some fiscal slippage.
• ▀ A slower narrowing of fiscal deficits than we forecast wouldn't automatically lead to a period of above-target inflation. Indeed, we wouldn't be surprised if larger-than-expected deficits were associated with weak inflation.
• ▀ High levels of corporate debt and weak labour markets raise the risk of private sector retrenchment ahead. In that case, large and sustained fiscal deficits may be needed to fill the vacuum and prevent GDP and inflation from falling. As has been the case in Japan over the past 25 years, large deficits over coming years could be associated with weak GDP growth and below-target inflation.
• ▀ If economies begin to overheat but governments keep fiscal policy loose, inflation could, of course, pick up. But central bank tightening would offset it. We believe the risk of sustained inflation overshoots is limited unless monetary policy were made subservient to governments’ own objectives. And we think the risk of central banks losing independence remains slim.

     

Diversification discount,information rents,and internal capital markets

While many existing studies report that corporate diversification destroys shareholder value, several recent studies challenge these findings. Schoar [Schoar, A. (2002). Effects of corporate diversification on productivity. The Journal of Finance, 57, 2379?2403] finds that plants in conglomerates are more productive than those in comparable single-segment firms, although conglomerates are traded at discounts. Villalonga [Villalonga, B. (2004a). Diversification discount or premium? New evidence from the business information tracking services. The Journal of Finance, 59, 479–506; Villalonga, B. (2004b). Does diversification cause the “diversification discount”. Financial Management, 33, 5?27] employs a more comprehensive database and statistical techniques than those used in the prior studies, and shows that there is a diversification premium, rather than discount. This paper develops a model that highlights the costs and benefits of corporate diversification. The diversified firm trades off the benefits of more efficient resource allocation through its internal capital market against the costs of information rents to division managers, which are necessary for effective workings of the internal capital market. We provide an argument supporting Schoar's findings, and identify conditions under which there can be a diversification discount or a premium.     

Inflation tax in the lab: a theoretical and experimental study of competitive search equilibrium with inflation

In this paper we measure the effect of the inflation tax on economic activity and welfare within a controlled setting. To do so, we develop a model of price posting and monetary exchange with inflation and finite populations. The model, which provides a game–theoretic foundation to Rocheteau and Wright (2005)׳s competitive search monetary equilibrium, is used to derive theoretical propositions regarding the effects of inflation in this environment, which we test with a laboratory experiment that closely implements the theoretical framework. We find that the inflation tax is harmful – with cash holdings, production and welfare all falling as inflation rises – and that its effect is relatively larger at low inflation rates than at higher rates. For instance, for inflation rates between 0% and 5%, welfare in the two markets we consider (2[seller]×2[buyer] and 3×2) falls by roughly 1 percent for each percentage–point rise in inflation, compared with 0.4 percent over the range from 5% to 30%. Our findings lead us to conclude that the impact of the inflation tax should not be underestimated, even under low inflation.     

The return to schooling: Estimates from a sample of young Australian twins

This study uses a sample of young Australian twins to examine whether the findings reported in [Ashenfelter, Orley and Krueger, Alan, (1994). ‘Estimates of the Economic Return to Schooling from a New Sample of Twins’, American Economic Review, Vol. 84, No. 5, pp.1157–73] and [Miller, P.W., Mulvey, C and Martin, N., (1994). ‘What Do Twins Studies Tell Us About the Economic Returns to Education?: A Comparison of Australian and US Findings’, Western Australian Labour Market Research Centre Discussion Paper 94/4] are robust to choice of sample and dependent variable. The economic return to schooling in Australia is between 5 and 7 percent when account is taken of genetic and family effects using either fixed-effects models or the selection effects model of Ashenfelter and Krueger. Given the similarity of the findings in this and in related studies, it would appear that the models applied by [Ashenfelter, Orley and Krueger, Alan, (1994). ‘Estimates of the Economic Return to Schooling from a New Sample of Twins’, American Economic Review, Vol. 84, No. 5, pp.1157–73] are robust. Moreover, viewing the OLS and IV estimators as lower and upper bounds in the manner of [Black, Dan A., Berger, Mark C., and Scott, Frank C., (2000). ‘Bounding Parameter Estimates with Nonclassical Measurement Error’, Journal of the American Statistical Association, Vol. 95, No.451, pp.739–748], it is shown that the bounds on the return to schooling in Australia are much tighter than in [Ashenfelter, Orley and Krueger, Alan, (1994). ‘Estimates of the Economic Return to Schooling from a New Sample of Twins’, American Economic Review, Vol. 84, No. 5, pp. 1157–73], and the return is bounded at a much lower level than in the US.     

Are professional forecasters overconfident?

Do professional forecasters have an accurate sense of the uncertainties surrounding their own forecasts? This paper examines forecaster overconfidence by comparing ex ante, surveyed forecaster uncertainty with ex post, realised uncertainty based on the dispersion of an individual’s forecast errors. Unlike the literature that focuses on consensus forecasts, our focus is at the level of the individual forecaster. Using microdata from the three major surveys of professional forecasters (Euro Area, US and UK), we examine real GDP growth forecasts over the period 1999–2015. Our findings show that overconfidence dominates among individual forecasters, particularly for longer forecast horizons, and that individual forecasters appear to have little understanding of their own uncertainty.     

Asymptotics for out of sample tests of Granger causality

This paper presents analytical, Monte Carlo and empirical evidence concerning out-of-sample tests of Granger causality. The environment is one in which the relative predictive ability of two nested parametric regression models is of interest. Results are provided for three statistics: a regression-based statistic suggested by Granger and Newbold [1977. Forecasting Economic Time Series. Academic Press Inc., London], a t-type statistic comparable to those suggested by Diebold and Mariano [1995, Comparing Predictive Accuracy. Journal of Business and Economic Statistics, 13, 253–263] and West [1996. Asymptotic Inference About Predictive Ability, Econometrica, 64, 1067–1084], and an F-type statistic akin to Theil's U. Since the asymptotic distributions under the null are nonstandard, tables of asymptotically valid critical values are provided. Monte Carlo evidence supports the theoretical results. An empirical example evaluates the predictive content of the Chicago Fed National Activity Index for growth in Industrial Production and core PCE-based inflation.     

Does domestic cooperation lead to business-cycle convergence and financial linkages?

We test for convergence – à la Massmann and Mitchell [Massmann, M., & Mitchell, J. (2004). Reconsidering the evidence: Are Euro area business cycles converging? Journal of Business Cycle Measurement and Analysis, 1(3), 275–307] – among the industrial sectors of some APEC members—Japan, South Korea, Malaysia, Mexico, the U.S. and Canada for January 1971–March 2004; and, Australia, Japan and South Korea for 1957:01–2003:04. We conclude that business-cycle convergence is far from complete. We also reject convergence in the stock and exchange rate markets. A less stringent definition of co-movement, due to Vahid and Engle [Vahid, F., & Engle, R. (1993). Common trends and common cycles. Journal of Applied Econometrics, 8(4), 341–360], provides evidence of common cycles in the industrial sectors of Australia, Japan and South Korea, and in the stock and exchange rate markets of developed and growth-competitive economies belonging to APEC.     

Dynamic gap transformations: Are banks asset – transformers or brokers? or both?

We study the sensitivity of bank stock returns to interest rates, by extending existing tests in two important directions. We incorporate dynamic gap adjustments and extend the traditional duration gap measure to new gap measures based on the general equilibrium term structure model developed by Longstaff and Schwartz [Longstaff, F. A., & Schwartz, E. S. (1992). Interest-rate volatility and the term structure: A two-factor general equilibrium model. Journal of Finance, 47(4), 1259–1282]. Consistent with previous studies, the results indicate that banks hedge against changes in interest rate levels, when the levels are low, and speculate when the levels are high, but the volatility is low.     

Deficits,expected deficits,financial markets,and the economy

This paper assesses the implications of U.S. budget and current account deficits for financial and economic stability. The primary focus is on the behavior of interest rates in response to deficits, then effects on the economy through the financial system. The paper argues, and shows with empirical evidence, including from a large-scale econometric model, that expected, but not realized, budget deficits affect interest rates. Under certain circumstances, particularly near full employment, sustained budget and current account deficits can lead to financial disarray and a severely constrained economy.     

Net treasury borrowing and interest-rate changes

As noted by Arora and Dua (1993, 1995), studies investigating the relationship between budget deficits and short-term interest rates have generated inconsistent results. This study performs Granger causality tests on four short-term interest rates using changes instead of level measures. In lieu of deficit, the level of net treasury borrowing will serve as thex variable.     

Will Inflation Follow Rapid Monetary Growth?

Do rapid rates of monetary growth imply an acceleration in inflation? Gordon Pepper, an adviser and director of Midland Montagu, argues that current rates of monetary growth are too rapid.     

The Incremental Predictive Information Associated with Using Theoretical New Keynesian DSGE Models vs. Simple Linear Econometric Models*

In this paper we construct output gap and inflation predictions using a variety of dynamic stochastic general equilibrium (DSGE) sticky price models. Predictive density accuracy tests related to the test discussed in Corradi and Swanson [Journal of Econometrics (2005a), forthcoming] as well as predictive accuracy tests due to Diebold and Mariano [Journal of Business and Economic Statistics (1995) , Vol. 13, pp. 253–263]; and West [Econometrica (1996) , Vol. 64, pp. 1067–1084] are used to compare the alternative models. A number of simple time‐series prediction models (such as autoregressive and vector autoregressive (VAR) models) are additionally used as strawman models. Given that DSGE model restrictions are routinely nested within VAR models, the addition of our strawman models allows us to indirectly assess the usefulness of imposing theoretical restrictions implied by DSGE models on unrestricted econometric models. With respect to predictive density evaluation, our results suggest that the standard sticky price model discussed in Calvo [Journal of Monetary Economics (1983), Vol. XII, pp. 383–398] is not outperformed by the same model augmented either with information or indexation, when used to predict the output gap. On the other hand, there are clear gains to using the more recent models when predicting inflation. Results based on mean square forecast error analysis are less clear‐cut, although the standard sticky price model fares best at our longest forecast horizon of 3 years, it performs relatively poorly at shorter horizons. When the strawman time‐series models are added to the picture, we find that the DSGE models still fare very well, often outperforming our forecast competitions, suggesting that theoretical macroeconomic restrictions yield useful additional information for forming macroeconomic forecasts.     

A NOTE ON THE GRAS METHOD

The GRAS method as presented by Junius and Oosterhaven [Junius, T. and J. Oosterhaven (2003) The Solution of Updating or Regionalizing a Matrix with Both Positive and Negative Elements. Economic Systems Research, 15, 87–96] assumes that every row and every column of a matrix to be balanced has at least one positive element. This might not necessarily be true in practice, in particular, when dealing with large-scale input–ouput tables, supply and use tables, social accounting matrices, or, for that matter, any other matrix. In this short note we relax this assumption and make available our MATLAB program for anyone interested in matrix GRASing. The same issue arises in the presentations of the KRAS method [Lenzen, M., B. Gallego and R. Wood (2009) Matrix Balancing Under Conflicting Information. Economic Systems Research, 21, 23–44] and the SUT–RAS method [Temurshoev, U. and M.P. Timmer (2011) Joint Estimation of Supply and Use Tables. Papers in Regional Science, 90, 863–882], which should be accordingly accounted for in their empirical applications.     

Around the world with Irving Fisher

This paper aims to show why Irving Fisher's own data on interest rates and inflation in New York, London, Paris, Berlin, Calcutta, and Tokyo during 1825–1927 suggested to him that nominal interest rates adjusted neither quickly nor fully to changes in inflation, not even in the long run. In Fisher's data, interest rates evolve less rapidly than inflation and change less than inflation over time. Even so, the “Fisher effect” is commonly defined as a point-for-point effect of inflation on nominal interest rates rather than what Fisher actually found: a persistent negative effect of increased inflation on real interest rates.     

Iterated weak dominance and subgame dominance

In this paper, we consider finite normal form games satisfying transference of decisionmaker indifference. We show that any set of strategies surviving k rounds of elimination of some weakly dominated strategies can be reduced to a set of strategies equivalent to the set of strategies surviving k rounds of elimination of all weakly dominated strategies in every round by (at most k) further rounds of elimination of weakly dominated strategies. The result develops work by Gretlein [Gretlein, R., 1983. Dominance elimination procedures on finite alternative games. International Journal of Game Theory 12, 107–113]. We then consider applications and demonstrate how we may obtain a unified approach to the work by Gretlein and recent results by Ewerhart [Ewerhart, C., 2002. Iterated weak dominance in strictly competitive games of perfect information. Journal of Economic Theory 107, 474-482] and Marx and Swinkels [Marx, L.M., Swinkels, J.M., 1997. Order independence for iterated weak dominance. Games and Economic Behavior 18, 219-245].     

Fertility and female labor supply in Latin America: New causal evidence

We study the effect of fertility on maternal labor supply in Argentina and Mexico exploiting a source of exogenous variability in family size first introduced by Angrist and Evans [Angrist, J., Evans, W., 1998. Children and their parents' labor supply: evidence from exogenous variation in family size. American Economic Review 88 (3), 450–577] for the United States. We find that the estimates for the US can be generalized both qualitatively and quantitatively to the populations of two developing countries where, compared to the US, fertility is known to be higher, female education levels are much lower and there are fewer formal facilities for childcare.
