Spillovers in Exchange Rates and the Effects of Global Shocks on Emerging Market Currencies

This paper provides an investigation into the spillover effects of exchange rate returns and volatility for developed and emerging market currencies, using data from 1997 to 2011. The results suggest that spillovers in exchange rate returns have increased steadily over time, in moderate reaction to economic events. In contrast, spillovers in total observed volatility (measured by squared returns) react more strongly to economic events, and this transmission has remained at a relatively high level since the global financial crisis. Furthermore, over the course of time, global shocks would appear to account for a larger proportion of aggregate exchange rate volatility (and the relative importance of domestic shocks has declined). The paper also considers whether the increase in volatility spillover is due to sudden shocks, or whether it is due to changes in the stochastic trend of the underlying volatility process. The results suggests that in most cases, this increase is due to sudden shocks, however, in certain instances country‐specific events may perpetuate changes to the trend of the underlying volatility spillover.     

Eastern Germany and the conflict between wage adjustment,investment, and employment: A numerical analysis

Eastern Germany and the Conflict between Wage Adjustment, Investment, and Employment: A Numerical Analysis. — In this paper, some light is shed on the dynamics of the adjustment process in eastern Germany by studying the linkages between the dynamics of wage adjustment, investment, and employment. An extended dynamic investment model, which includes adjustment costs for capital and revision costs for investment, is presented. This model is specified according to the east German economy and analyzed numerically by an optimization method based on direct collocation. Results are obtained for the time horizon of adjustment and for the implications of different wage strategies on the path of investment and employment.

The asymmetric behavior of household consumption under the business cycle

In this study, we examine whether and to what extent the pattern of household consumption is asymmetrically sensitive to economic changes. We use a threshold model with error correction to characterize household consumption under the business cycle. Using data from the 1979–2014 Survey of Family Income and Expenditure in Taiwan, we find that household consumption has pro-cyclical characteristics during the business cycle. More importantly, household consumption responds asymmetrically to economic fluctuations such that changes in consumption tend to be larger during expansions than during downturns. Furthermore, the nature of this asymmetry differs across household income quantiles.     

Unemployment or credit: Which one holds the potential? Results for a small open economy with a low degree of financialization

This paper investigates the relative importance of unemployment versus credit in determining the potential level of real activity for a small open economy with a low degree of financialization. We use a multivariate unobserved component model (MUC) to derive the potential output and the associated output gap for the Lithuanian economy. The model is estimated via Bayesian methods and the time paths of unobserved variables are extracted via the Kalman filter. The inclusion of unemployment in the MUC model substantially improves the estimates of the output gap in real time. Adding information about credit further emphasizes the overheating of the economy in the pre-crisis period, both in real time and ex post. Including credit preserves the conclusions regarding turning points. We uncover a strong negative correlation between the model-implied unemployment gap (without accounting for credit) and real credit growth. Data revisions do not appear to be the primary source of revisions of output gap estimates.     

Dynamic programming for valuing American options under a variance-gamma process

Lévy processes provide a solution to overcome the shortcomings of the lognormal hypothesis. A growing literature proposes the use of pure-jump Lévy processes, such as the variance-gamma (VG) model. In this setting, explicit solutions for derivative prices are unavailable, for instance, for the valuation of American options. We propose a dynamic programming approach coupled with finite elements for valuing American-style options under an extended VG model. Our numerical experiments confirm the convergence and show the efficiency of the proposed methodology. We also conduct a numerical investigation that focuses on American options on S&P 500 futures contracts.     

Re‐Examining the Role of Structural Change and Nonlinearities in a Phillips Curve Model for South Africa

Although studies generally find evidence of a Phillips curve‐type relationship in South Africa, uncertainty remains about the relevance of the model over a relatively long sample period, and whether conventional output gap measures are suitable proxies for demand pressure. This paper reviews research which shows that the Phillips curve model prevails over an extended sample, provided that the benchmark specifications include major structural changes in the balance‐of‐payments and labour market, and account for shifts in the root causes of inflation. When this is done, a linear specification with an output gap in levels correctly predicts the non‐trended inflation pattern over the period 1971(Q1)–1984(Q4), whereas a piecewise concave curve with an output gap in growth rates accurately forecasts the decelerating inflation pattern during 1986(Q1)–2001(Q2). A novel feature of the concave model is that it remains statistically robust and structurally stable when it is estimated until 2015(Q4). The concave model imparts a disinflationary bias, which suggests that monetary policy should be more expansionary during downswing phases of the business cycle and neutral during upswing phases. The analysis also considers how the shape of the Phillips curve might change if the balance‐of‐payments constraint on demand is relaxed in a significant way.     

Investigating properties of commodity price responses to real and nominal shocks

This paper studies dynamic adjustments of 49 world commodity prices in response to innovations in the nominal exchange rate and the world real GDP. After we estimate the dynamic elasticity of the prices with respect to these shocks, we obtain the kernel density of our estimates to establish stylized facts on the adjustment process of the commodity price toward a new equilibrium path. Our empirical findings imply, on average, that the law of one price holds in the long-run, whereas the substantial degree of short-run price rigidity was observed in response to the nominal exchange rate shock. The real GDP shock tends to generate substantial price fluctuations in the short-run because adjustments of the supply can be limited, but have much weaker effects in the long-run as the supply eventually counterbalances the increase in the demand. Overall, we report persistent long-lasting effects of the nominal exchange rate shock on commodity prices relative to those of the real GDP shock.     

Price recall: Brand and store type differences

Price is among the most important choice criteria for customers, whose price knowledge is often surprisingly inaccurate. This study aims at providing new insights into differences in price recall across brands and store types, and their potential effect on marketing efficiency and customers’ store choice. Towards this aim, we analyze the price recall of consumers for 51 food items by a random-effects panel estimation employing a survey with 715 participants. Our results show that customers recall national brand prices better than private labels, almost irrespectively of the store type; consumers overestimate store brand prices in both store types; the effect, however, is much higher for the convenience store. These outcomes have consequences for the marketing strategy: despite a price-matching guarantee for the store brands in the convenience store, the price image is still in favor of the discounter. This result raises doubts on the effectiveness of the price-matching guarantee, at least in this context. The everyday low price strategy of the discounter seems to pay off in terms of the price image. Though both stores charge the exact same prices for their store brands, prices at the discounter are on average perceived to be significantly lower.
