Testing the purchasing power parity through I(2) cointegration techniques

This paper contributes to the empirical literature on the purchasing power parity (PPP) over the post‐Bretton Woods period by providing a time‐series based interpretation of the controversial evidence characterizing the dynamics of real exchange rates. It is shown that the persistence of deviations from the PPP between a set of European countries and the United States may be empirically attributed to the presence of I(2) stochastic trends in prices using Consumer Price Indices. Interestingly, the slow adjustment towards the equilibrium can be modelled through ‘integral‐proportional’ equilibrium correction models and this evidence can be partly reconciled with theories where the inflation rate reduces the markup of profit‐maximizing firms acting on imperfectly competitive markets.

VARs,common factors and the empirical validation of equilibrium business cycle models

Equilibrium business cycle models have typically less shocks than variables. As pointed out by Altug (1989) International Economic Review 30 (4) 889–920 and Sargent (1989) The Journal of Political Economy 97 (2) 251–287, if variables are measured with error, this characteristic implies that the model solution for measured variables has a factor structure. This paper compares estimation performance for the impulse response coefficients based on a VAR approximation to this class of models and an estimation method that explicitly takes into account the restrictions implied by the factor structure. Bias and mean-squared error for both factor- and VAR-based estimates of impulse response functions are quantified using, as data-generating process, a calibrated standard equilibrium business cycle model. We show that, at short horizons, VAR estimates of impulse response functions are less accurate than factor estimates while the two methods perform similarly at medium and long run horizons.     

Learning for Sustainability Transition through Bounded Socio-technical Experiments in Personal Mobility

A bounded socio-technical experiment (BSTE) attempts to introduce a new technology, service, or a social arrangement on a small scale. Many such experiments in personal mobility are ongoing worldwide. They are carried out by coalitions of diverse actors, and are driven by long term and large scale visions of advancing society's sustainability agenda. This paper focuses on the processes of higher- order learning that occur through BSTEs. Based on the conceptual frameworks from theories of organizational learning, policy-oriented learning, and diffusion of innovation, we identify two types of learning: the first type occurs among the participants in the experiment and their immediate professional networks; the second type occurs in the society at large. Both types play a key role in the societal transition towards sustainable mobility systems. Two case studies, in which the Design for Sustainability Group at Technical University of Delft has participated, provide empirical data for the analysis. One case consists of development of a three-wheeled bike-plus vehicle (Mitka); the second case seeks to solve mobility problems on the Dutch island of Texel. We find that higher order learning of the first type occurs among the BSTE participants and beyond. Learning can be facilitated by deployment of structured visioning exercises, by diffusion of ideas among related BSTEs, by innovative couplings of problems and solutions, and by creating links among related experiments. Government agencies, universities and other intellectual entrepreneurs have key roles to play in making that happen. The cases provide much less insights about the second type of learning. Research on the latter is necessary.     

Uncertainty, Flexible Exchange Rates, and Agglomeration

This paper shows that exchange rate volatility promotes agglomeration of economic activity. Under flexible rates, firms prefer to locate in large countries, where they would enjoy lower variability of sales, thus reinforcing concentration of firms in such locations. Empirical evidence on OECD countries demonstrates that for small (large) countries or currency areas, exchange rate volatility has a long-run negative (positive) effect on net inward FDI flows. Two implications arise: creating a currency area fosters agglomeration towards the area and dispersion within the area. JEL Classification Numbers: F12, F31, F33, F4, L16, R12     

Cross Sectoral Variation in the Volatility of Plant Level Idiosyncratic Shocks

We estimate the volatility of plant–level idiosyncratic shocks in U.S. manufacturing. We measure the variation in Revenue Total Factor Productivity not explained by either industry or economy–wide factors, or by establishments’ characteristics. We find that idiosyncratic shocks are much larger than aggregate shocks, accounting for about 80% of the overall uncertainty faced by plants. Plants in the most volatile sector are subject to about six times as much idiosyncratic uncertainty as plants in the least volatile. We provide evidence suggesting that idiosyncratic risk is higher in industries where the extent of creative destruction is likely to be greater.     

Fertility,income and welfare in an OLG model with regulated wages

We analyse the effects of the regulation of wages in a standard one-sector OLG model of neoclassical growth extended to account for endogenous fertility decisions of households and unemployment benefit policies financed at balanced budget. In contrast with the prevailing literature, which has failed to pay due attention to inter-temporal contexts, our conclusion is that minimum wages may be introduced not only for equity reasons, that is, to increase the income of low-paid workers, but under suitable conditions—i.e., if production is sufficiently capital oriented and the unemployment benefits are high enough—minimum wage legislation might be considered as a source of increased economic performance despite unemployment, i.e. a regulated-wage economy performs better than a market-wage economy. As a consequence, since higher minimum wages raise per capita income together with increasing unemployment, our results imply that a positive correlation between unemployment and long-run income per-capita may exist. Further, the lifetime welfare of the representative generation may be increased as well. Finally, the wage rate may also be treated as a policy instrument for the control of population growth.

Consumer (goal) satisfaction: A means‐ends chain approach

This study investigates the role that service attributes, customer subgoals, and goals play in forming the satisfaction judgment. Drawing on means‐ends chain theory, and on satisfaction research, satisfaction is conceptualized as the result of a process in which customers activate multiple comparative referents. In a pilot study, a paper‐and‐pencil laddering technique was used to collect attributes and goals connected to the satisfaction judgment. These elements were then used as items in a satisfaction survey of 200 customers. A mixture regression model revealed that both attribute‐related dimensions and goal‐related dimensions determine overall satisfaction, albeit not homogeneously among customers. Two customer segments were identified: Socializers, whose satisfaction is driven primarily by the goal of well‐being, and Achievers, whose satisfaction is generated mainly by the goal of efficiency. Two directed graphs describe the satisfaction path of the two groups of customers, illustrating how service attributes are connected to the satisfaction of lower‐order and higher‐order goals. © 2011 Wiley Periodicals, Inc.     

Discretionary Government Consumption, Private Domestic Demand, and Crisis Episodes

This paper analyzes the dynamic impact of discretionary government consumption purchases on private demand. Using a panel of 132 countries from 1960 to 2008, we find that while discretionary changes in government consumption lead to crowding-in effects in the short run, crowding-out effects take over in the medium run. In addition, we also find that both short-term crowding-in and medium-term crowding out effects are amplified once we control for periods of crisis.
