PREDICTING SYSTEMATIC RISK WITH MACROECONOMIC AND FINANCIAL VARIABLES

We analyze the predictive power of several macroeconomic and financial indicators in forecasting quarterly realized betas of 30 industry and 25 size and book-to-market portfolios. We model realized betas as autoregressive processes of order 1 and include lagged values of macroeconomic and financial indicators as exogenous predictor variables. In out-of-sample forecasting exercises, forecasts using bond market variables as exogenous predictors statistically outperform forecasts from a benchmark model without any exogenous predictors. These forecasts based on bond market variables also economically outperform benchmark forecasts by providing better performance in hedging the market risk of portfolios.     

Testing PPP hypothesis under temporary structural breaks and asymmetric dynamic adjustments

ABSTRACT

We test the empirical validity of the PPP proposition under temporary structural breaks and dynamic nonlinear adjustments. Although several testing procedures have recently been proposed in the existing literature to investigate stochastic properties of the series under gradual breaks and nonlinear adjustments, none of these tests are compatible with the PPP proposition. Therefore, we propose new testing procedures that restrict the break to be temporary while simultaneously allowing for asymmetric dynamic nonlinear adjustment towards equilibrium. Using these newly proposed tests, we test stationarity of real exchange rate of 24 OECD countries vis-à-vis USA, and find support in favour of PPP proposition in majority of the countries.     

Is real per capita state personal income stationary? New nonlinear,asymmetric panel-data evidence

This paper re-examines the stochastic properties of U.S. state real per capita personal income, using new panel unit-root procedures. The new developments incorporate non-linearity, asymmetry, and cross-sectional correlation within panel-data estimation. Including nonlinearity and asymmetry finds that 43 states exhibit stationary real per capita personal income whereas including only nonlinearity produces 42 states that exhibit stationarity. Stated differently, we find that two states exhibit nonstationary real per capita personal income when considering nonlinearity, asymmetry, and cross-sectional dependence.

The interest rate–inflation relationship under an inflation targeting regime: The case of Turkey

This paper examines the relationship between nominal interest rates and the expected inflation rate for the Turkish economy between 2002 and 2009, a period when the inflation-targeting regime was implemented as monetary policy. We use the test of cointegrating rank with a trend-break (a method introduced by Inoue, 1999) and we also apply exogeneity tests. Empirical findings indicate that monetary policy rates depend on inflationary expectations; long-term interest rates are affected by monetary policy; and the weak form of the Fisher effect is valid. This evidence implies that monetary policy has actually influenced the real long-term interest rates; the inflation targeting regime pursued by the Central Bank of Turkey is reliable; and hence realized inflation has remained close to its targeted level.

Exchange Rate Pass-Through in Vertically Related Markets

The paper provides a theoretical framework which addresses exchange rate pass-through within the setting of vertically related markets. In particular, foreign firms' price adjustment in response to an exchange rate shock is evaluated. This permits study of the importance of cost effects of the exchange rate shock. Recent empirical evidence indicated the relevance of these cost effects. It is shown that one can decompose the effects of an exchange rate shock on the final goods market into direct and indirect components. The indirect effect works through the input market. The degree of pass-through then depends on the relative importance of direct and indirect effects, which in turn depends on the nature of vertical structures and strategic firm behavior. It is shown that the institutional aspects of vertically related markets play a role in explaining incomplete price adjustments in both intermediate and final goods markets and the failure of PPP in the short run.     

Food price increases and net food importing countries: lessons from the recent past

Recent increases in food and other commodity prices have highlighted concerns that many poor countries are net food importers and higher food prices would worsen their trade balances. In this article, we analyze the changes in food trade balances associated with the 32% increase in food prices from 2000/2001 to 2004/2005. We find a small deterioration in food trade balances of low‐income countries and an improvement in middle‐income countries. The deterioration is most severe for countries in conflict and small island states, so attention should be placed first on these countries and on a few very‐low‐income countries that are also vulnerable. Because low‐income countries as a group had much lower agricultural GDP growth rates than middle‐income countries, the answers to food vulnerability in low‐income countries should probably be addressed within the context of incentives for agricultural production.     

Monetary policy implications of short-term capital flows in Turkey

The advent of global financial crisis in 2008, unleashed volatile short term capital flows to the emerging markets. This has forced many central banks in the developing world to adopt innovative policy measures to address concerns related to financial instability caused by the volatile nature of capital flows. In 2010 Turkish Central Bank included financial stability in addition to price stability as one of primary goals of its monetary policy. Several macro-prudential measures had been taken and ‘corridor system’ of setting the short-term policy rates had been introduced. In this paper, we have estimated an extended Taylor rule, using error correction model, to examine the impact of global financial factors in impacting the setting up of the policy rate in the pre and post 2010 periods in Turkey. It has been found that in the post-2010 period, global financial factors and monetary policy stance of the core economy, USA, have become major factor(s) in shaping up the monetary policy. Particularly our results of variance decomposition show that global financial indicators such as, VIX and EMBI have taken prominence in the setting of the short-term policy rate. This has not only made the domestic monetary more dependent on external factors but has also made pro-cyclical in nature.     

Real interest rates: nonlinearity and structural breaks

Real interest rate is a crucial variable that determines the consumption, investment and saving behavior of individuals and thereby acts as a key policy tool that the central banks use to control the economy. Although many important theoretical models require the real interest rates to be stationary, the empirical evidence accumulated so far has not been able to provide conclusive evidence on the mean reverting dynamics of this variable. To resolve this puzzle we re-investigate the stochastic nature of the real interest rates by developing unit root tests for nonlinear heterogeneous panels where the alternative hypothesis allows for a smooth transition between deterministic linear trends around which stationary asymmetric adjustment may occur. When the newly developed panel unit root tests are applied to the real interest rates of the 17 OECD countries, we were able to uncover overwhelming empirical support in favor of mean reversion in the short-run and long-run real interest rates. Therefore, these results show that the conclusions drawn from a miss-specified test that ignores the presence of either nonlinearity, structural breaks or cross sectional dependence can give quite misleading results about the stochastic behavior of the real interest rates.
