Measuring Persistence in Inflation: Evidence For angola

The purpose of this paper is to examine the degree of persistence in five inflation indicators for Angola, and to identify the implications for decision making. Our results suggest that when structural breaks are accounted for, all five inflation indicators are stationary. Second, our findings suggest that persistence is not too high. Moreover, the degree of persistence is similar among the five inflation indicators and throughout the sample period. Finally, our results also show that extracting the most volatile components of the headline inflation indicator does not generate a new inflation indicator that is less volatile and more persistent than the original. These results have important policy implications as the National Bank of Angola is preparing to change its monetary policy focus to a more inflation‐targeting regime.     

Informality in an economy with active labour courts

Job regulations and the justice branch interfere on several aspects of labour contracts. We build a model which explores the role of labour courts on the wage distribution in both formal and informal sectors. We obtain that the presence of active labour courts produces a negative relation between the wage gap and the productivity of the worker, a regularity documented in the empirical literature. Active labour courts also reduce informality of unskilled workers but do not have an impact on informality of skilled workers. Some elements and implications of our model are tested using Brazilian data.     

In search of stabilization and recovery: macro policy and reforms in Venezuela

Venezuela is currently immersed in a severe economic crisis as a result of years of domestic mismanagement and the recent reversal in oil prices. This article attempts to formulate a proposal for stabilization and recovery that includes upfront key policy actions to deal with the drastic foreign exchange constraint. We consider the recovery of foreign currency liquidity to be of paramount importance. This will allow not only the lifting of exchange control and the implementation of a stable and competitive real exchange rate, but also the removal of shortages across the board and output recovery. The recovery of domestic activity will also require supply-side relief in the form of broad deregulation, institutional changes, and a sensible policy to lift price controls. To maintain a stable and competitive exchange rate, we propose a whole set of policy measures for rapid suppression of inflation and the causal mechanisms that have formed over the years. A monetary reform and the support of monetary and fiscal policy for successful stabilization and recovery efforts are also discussed.     

Evaluación del efecto de la psicología del inversionista en un mercado bursátil artificial mediante su grado de eficiencia

The main objective in this paper is developing a cellular automaton model where interact more than one kind of broker, where the use and exchange of information between the investors explain the complexity through the Hurst coefficient estimation, this, represents an efficient or random market when the value is equal to 0.5. Due to the variants proposed in this research it can be determined that should exist a rational component in the simulator in order to generate an efficient behavior.     

Determinants of external imbalances: The role of taxes, government spending, and productivity

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses on real factors that determine the evolution of saving and investment and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to labor input, and tax policy shocks. While our approach is in line with the real business cycle models of the current account, the distinguishing feature of the work is the application of econometric methods to time series data for a small open economy so as to directly estimate the parameters governing saving and investment under rational expectations restrictions.     

Monetary announcements and stock prices in Israel

Responses of stock prices to monetary announcements in Israel are examined. Only the unexpected part of monetary injection announcements are found to have a significant impact on stock prices. Unlike findings for the U.S., this impact is positive.     

Sequential peak-load pricing: the case of airports and airlines

Abstract.  We investigate airport peak-load pricing using a vertical structure of airport and airlines. We find that a profit-maximizing airport would charge higher peak and off-peak runway prices and a higher peak/off-peak price differential than a public airport. Consequently, airport privatization would lead to both fewer total passengers and fewer passengers in the peak period. Although peak-travelling passengers benefit from fewer delays, this low level of peak congestion is not efficient, suggesting that airport privatization cannot be judged based on its effect on congestion alone. We also examine pricing behaviour of a public airport constrained to charge a time independent price.     

How do banks set interest rates?

This paper studies cross-sectional differences in banks interest rates. It adds to the literature in two ways. First, it analyzes systematically the micro and macroeconomic factors that influence the price-setting behaviour of banks. Second, by using banks’ prices (rather than quantities) it provides an alternative way of disentangling loan supply from loan demand shift in the “bank lending channel” literature. The results suggest that heterogeneity in the banking rates pass-through - depending on liquidity, capitalization and relationship lending - exists only in the short run.     

Macroeconometric testing of the rational expectations and structural neutrality hypotheses for the United States

Empirical tests of the neutrality of money growth found in recent literature are tests of the joint hypothesis of rational expectations and structural neutrality. Although tests of this joint hypothesis are informative, it is also important to gain information on the accuracy of its constituents. This paper presents the application of a methodology capable of providing information on the empirical validity of the rational expectations, structural neutrality, and joint hypotheses. Tests of these hypotheses are performed on the basis of FIML estimation of an extended version of a model recently presented by Robert Barro, using U.S. data for 1946–1973.     

Does a clustered location matter for high-technology companies' performance? The case of biotechnology in the Netherlands

Young entrepreneurial companies in biotechnology tend to cluster in space, nearby research universities and research centers. This pattern is often ascribed to the availability of external economies, mainly local knowledge spillovers that help to reduce the uncertainty from a disruptive technology faced by these companies. Given a shortage of empirical research on cluster advantages and performance of clustered companies, we present results of a comparative analysis of clustered and non-clustered companies in biotechnology and Bionanotechnology in the Netherlands. It appears that, among other influences, a clustered location has no significant influence on innovation and speed of growth. However, a location in the largest cluster (Leiden) does contribute to a better performance in terms of innovativeness compared with all other locations. The kind of external economies involved seems to vary according to the stage in the knowledge value chain and the segment in biotechnology industry. Knowledge spillovers tend to be local for companies involved in new drugs and diagnostics research only in the first stage of the knowledge chain and for service companies regardless of the stage in the knowledge chain.
