Working Paper
Indeterminacy and forecastability

Recent studies document the deteriorating performance of forecasting models during the Great Moderation. This conversely implies that forecastability is higher in the preceding era, when the economy was unexpectedly volatile. We offer an explanation for this phenomenon in the context of equilibrium indeterminacy in dynamic stochastic general equilibrium models. First, we analytically show that a model under indeterminacy exhibits richer dynamics that can improve forecastability. Then, using a prototypical New Keynesian model, we numerically demonstrate that indeterminacy due to passive ...

Variable Selection and Forecasting in High Dimensional Linear Regressions with Structural Breaks

This paper is concerned with the problem of variable selection and forecasting in the presence of parameter instability. There are a number of approaches proposed for forecasting in the presence of breaks, including the use of rolling windows and exponential down-weighting. However, these studies start with a given model specification and do not consider the problem of variable selection, which is complicated by time variations in the effects of signal variables. In this study we investigate whether or not we should use weighted observations at the variable selection stage in the presence of ...

Catalytic IMF? a gross flows approach

The financial assistance the International Monetary Fund (IMF) provides is assumed to catalyze fresh investment. Such a catalytic effect has, however, proven empirically elusive. This paper deviates from the standard approach based on the net capital inflow to study instead the IMF?s catalytic role in the context of gross capital flows. Using fixed-effects regressions, instrumental variables and local projection methods, we find significant differences in how resident and foreign investors react to IMF programs as well as in inward and outward flows. While IMF lending does not catalyze ...

Working Paper
Reserves and Risk: Evidence from China

We consider if the Chinese accumulation of reserves is associated with unintended consequences in the form of increased private sector risk taking. Using sovereign credit default swap spreads and stock index prices as indicators of risk taking, we provide evidence to suggest that as reserve holdings increase, so does the willingness of the private sector to take on more risk. This is an important finding that adds credence to the suggestion that insurance through costly reserves, to be used in the event of a crisis, may lead to private sector actions that in and of themselves make it more ...

Working Paper
Assessing Bayesian model comparison in small samples

We investigate the Bayesian approach to model comparison within a two-country framework with nominal rigidities using the workhorse New Keynesian open-economy model of Martnez-Garca and Wynne (2010). We discuss the trade-offs that monetary policy characterized by a Taylor-type rule faces in an interconnected world, with perfectly flexible exchange rates. We then use posterior model probabilities to evaluate the weight of evidence in support of such a model when estimated against more parsimonious specifications that either abstract from monetary frictions or assume autarky by means of ...

Working Paper
Distribution capital and the short- and long-run import demand elasticity

International business-cycle models assume that home and foreign goods are poor substitutes. International trade models assume they are close substitutes. This paper constructs a model where this discrepancy is due to frictions in distribution. Imports need to be combined with a local non-traded input, distribution capital, which is slow to adjust. As a result, imported and domestic goods appear as poor substitutes in the short run. In the long run this non-traded input can be reallocated, and quantities can shift following a change in relative prices. Thus the observed substitutability ...

Financial markets forecasts revisited: are they rational, herding or bold?

We test whether professional forecasters forecast rationally or behaviorally using a unique database, QSS Database, which is the monthly panel of forecasts on Japanese stock prices and bond yields. The estimation results show that (i) professional forecasts are behavioral, namely, significantly influenced by past forecasts, (ii) there exists a stock-bond dissonance: while forecasting behavior in the stock market seems to be herding, that in the bond market seems to be bold in the sense that their current forecasts tend to be negatively related to past forecasts, and (iii) the dissonance is ...

Working Paper
Leverage constraints and the international transmission of shocks

Recent macroeconomic experience has drawn attention to the importance of interdependence among countries through financial markets and institutions, independently of traditional trade linkages. This paper develops a model of the international transmission of shocks due to interdependent portfolio holdings among leverage-constrained financial institutions. In the absence of leverage constraints, international portfolio diversification has no implications for macroeconomic comovements. When leverage constraints bind, however, the presence of diversified portfolios in combination with these ...

Working Paper
Minimum wages and firm employment: evidence from China

This paper studies how minimum wage policies affect firm employment in China using a unique county level minimum wage data set matched to disaggregated firm survey data. We investigate both the effect of imposing a minimum wage, and the effect of the policies that tightened enforcement in 2004. We find that the average effect of minimum wage changes is modest and positive, and that there is a detectable effect after enforcement reform. Firms have heterogeneous responses to minimum wage changes which can be accounted for by differences in their wage levels and profit margins: firms with high ...

Working Paper
Size, openness, and macroeconomic interdependence

The curse of dimensionality, a problem associated with analyzing the interaction of a relatively large number of endogenous macroeconomic variables, is a prevailing issue in the open economy macro literature. The most common practice to mitigate this problem is to apply the so-called Small Open Economy Framework (SOEF). In this paper, we aim to review under which conditions the SOEF is a justifiable approximation and how severe the consequences of violation of key conditions might be. Thereby, we use a multicountry general equilibrium model as a laboratory. ; First, we derive the conditions ...
