ESTIMATING SARB'S POLICY REACTION RULE

This paper uses a Dynamic Stochastic General Equilibrium (DSGE) model to estimate the South African Reserve Bank's (SARB) policy reaction rule. We find that the SARB has a stable rule very much in line with those estimated for Canada, UK, Australia and New Zealand. Relative to other emerging economies the policy reaction function of the SARB appears to be much more stable with a consistent anti inflation bias, a somewhat larger weight on output and a very low weight on the exchange rate.     

When Does Economic Growth Reduce Poverty and Strengthen the Middle Class? A State-Level,Sector-Specific Analysis of Peru

Using novel state-level data of Peru from 1997 to 2010, we investigate how growth in different sectors affects poverty rates and the middle class. Our results indicate that only the manufacturing sector seems to robustly decrease poverty. Growth in the service sector emerges as a meaningful predictor of a rising middle class. Allowing for regional differences, we find substantial variation across the 25 Peruvian states with large shifts in magnitudes, signs, and statistical importance. Beyond the immediate implications for Peru, these findings highlight the importance of analyzing the link between economic performance and poverty rates on a subnational level. Policy implications are likely to differ substantially, depending on the source of economic growth and regional particularities.     

An econometric analysis of the main components of M3 in the Euro area

An Econometric Analysis of the Main Components of M3 in the Euro Area. — The main result is that the four components of M3 in the euro area can be explained in terms of a small set of explanatory variables (nominal GDP and interest rates) for the sample period January 1990 — September 1999 both in terms of levels and as shares of M3. Moreover, overall cointegration tests broadly support the hypothesis of long-run stability of the demand for the components of M3 and for M3 itself in nominal terms. Around the start of Stage Three of Monetary Union significant substitution between the components of M3 is detected. A refinement of the empirical analysis takes into account the correlation of the unexplained movements of the individual components using the SUR technique.     

Selecting public goods institutions: Who likes to punish and reward?

We study the link between individual attitudes toward uncertainty on the one hand, and preferences over, as well as behavior within, various public goods institutions on the other hand. We incentive‐compatibly elicit preferences over voluntary contribution mechanisms with and without reward and punishment options and then randomly assign subjects to play in one of the four institutions. We find that payoffs are significantly greater when punishment is allowed but that only a small minority of participants prefers such an environment. Somewhat surprisingly, preferences over institutions are generally independent of individual characteristics. Conversely, individual characteristics, including institutional preferences, are significantly predictive of behavior in the public goods game. For instance, risk‐averse individuals preemptively punish more often. This suggests that when studying sanctions and rewards, it is important to consider individual attitudes toward risk and uncertainty—although they may not affect the original selection into institutions.     

Does uncertainty affect economic growth? An empirical analysis

Does Uncertainty Affect Economic Growth? An Empirical Analysis. — This paper investigates the effect of uncertainty on economic growth. We construct measures of export uncertainty, government policy uncertainty and price uncertainty to augment a growth model, and using econometric techniques we test for robustness of the effects of these measures on economic growth in a cross-section of 138 developing and developed economies during the 1970–1995 period. The result clearly shows a robust and negative effect of uncertainty on economic growth. These results underline the importance of export stability and policy credibility.     

The response of long-term interest rates to news about monetary policy actions: Empirical evidence for the U.S. and Germany

The Response of Long-Term Interest Rates to News about Monetary Policy Actions. Empirical Evidence for the U.S. and Germany. — The authors reestimate the expectations theory of the term structure focusing on the question of how monetary policy actions indicated by changes in the very short rate affect long-term interest rates. Their main point is that the expectations hypothesis implies that very long rates should only react to unanticipated changes of the very short rate. In contrast to cointegration tests of expectations theory, this implication only requires rational expectations but not stationary risk premia. Therefore, its empirical test sheds new light on the importance of expectations theory for the determinants of the term structure of interest rates.     

Real business cycles in an open economy: An application to Germany

Real Business Cycles in an Open Economy: An Application to Germany. — This paper discusses a stochastic, dynamic-optimizing model of an open economy. It is closely related to small open economy models, but differs by introducing an upward-sloping supply curve of foreign bonds. The model is calibrated to match the long-run features of Germany. The simulations show that the model is consistent with the observed regularities of German business fluctuations.     

Private Goods,Public Goods,and Common Pools with Homo Reciprocans

Familiar inefficiencies arise with competing interests over private goods in Stackelberg and investment games. Private good experiments reveal whether reciprocity enhances cooperative outcomes. Familiar social dilemmas arise with voluntary provision of public goods and voluntary appropriation from common pools. Experiments with pairs of payoff‐equivalent provision and appropriation games reveal whether reciprocity is more or less effective in ameliorating under‐provision or over‐appropriation. Experiments with asymmetric provision and appropriation games also yield insight into the effects of the Indian caste system on inefficiency from social dilemmas. Experiments with three types of games, with a private good, public good or common pool, provide diagnostic tests of the homo reciprocans model.     

Interaction between structural and cyclical shocks in production and employment

Interaction between Structural and Cyclical Shocks in Production and Employment. — A major aim of recent empirical modelling of the business cycle is to identify the relative importance of aggregate supply and demand shocks. This paper uses the methodology of unobserved (or structural) components time series models for the identification of technology and demand shocks in a two-equation system of structural labour productivity and industrial output. It allows us to introduce the correlation between the structural and cyclical shocks such that the mutual dependency of these shocks can be estimated explicitly. The data is quarterly time series of labour productivity in industry and industrial output for Germany, the Netherlands, the United Kingdom and the United States. Our results show that the covariance of the dynamics of structural and cyclical shocks appears to be important in these countries.
