Trust Me! I am a European Central Banker

In the aftermath of the financial crisis, the European Central Bank (ECB) has experienced an unprecedented deterioration in the level of trust. This raises the question as to what factors determine trust in central banking. We use a unique cross‐country data set that includes a rich set of socioeconomic characteristics and supplement it with variables meant to reflect a country's macroeconomic condition. We find that besides individual socioeconomic characteristics, macroeconomic conditions play a crucial role in the trust‐building process. Our results suggest that agents are boundedly rational in the trust‐building process and that current ECB market operations may even be beneficial for trust in the ECB in the long run.

Regime-switching effects of debt on real GDP per capita the case of Latin American and Caribbean countries

In this paper, we try to investigate how the debt and real GDP per capita relationship varies with indebtedness levels and other country characteristics in a balanced panel of 21 developing Latin American and Caribbean countries over the period 1992–2006. The empirical results indicate that there exist two threshold values of 32.88% and 55.89%. The latter is lower than the Maastricht criterion and Stability and Growth Pact of a total external Debt per GDP ratio at 60% in the OECD countries. Both thresholds divide our panel into three regimes. In the middle (stimulus) regime, the Debt per GDP ratio has a positive impact on real GDP per capita, which is consistent with the stimulus view (Eisner, 1984). However, the impact becomes negative and consistent with the crowding-out view (Friedman, 1977, 1985) in the left and right (crowding-out) regimes. Based on our findings, we find no supportive evidence for Ricardian view (Barro, 1989). Therefore, our empirical results have important implications for fiscal policymakers in these Latin American and Caribbean countries.

Public debt and financial development

We examine the role of public debt in financial development. The literature has highlighted its supportive role through providing collateral and benchmark. We contrast this “safe asset” view to a “lazy banks” view: developing banking sectors that lend mainly to the public sector may develop more slowly, because it could make banks profitable but inefficient. Results from country-level and bank-level regressions are more supportive of the “lazy banks” view, but the “safe asset” view seems to play a role at moderate levels of public debt held by banks. There is also evidence of a harmful interaction between public debt and financial repression.

Modeling the act of measurement in the social sciences

Motivated by time-series experimental designs, we develop a model of the act of measurement in the social sciences. Meaningful measurements are represented by operators that obey a non-commutative algebra. Thus, the order in which information is extracted matters. In addition, responses to questions about an attribute depend on whether information about another attribute has previously been extracted. Measurement “forces” the subject to obtain one value of the attribute, the one measured by the observer. An uncertainty principle imposes a fundamental limit on the ability to extract detailed information about two distinct attributes within a short period of time.     

On the robustness of simple and optimal monetary policy rules

This is a discussion of the paper “Simple versus Optimal Rules as Guides to Policy” by Brock, Durlauf, Nason and Rondina (BDNR) presented in November 2006 at Carnegie-Mellon University under the auspices of the Carnegie-Rochester Conference Series on Public Policy. I review the authors’ arguments, present a few suggestions for extension and outline where I think at least one strand of the literature should be heading.     

The importance of seasonal variability and tactical responses to risk on estimating the economic benefits of integrated weed management

Seasonal variability is an important source of risk faced by farmers and, regardless of an individual's attitude to risk, there are options to tactically adjust production strategies as the outcomes of risk become known. The objective of this article is to measure the economic benefits of alternative approaches to managing weeds, one of the most serious production problems in Australian cropping systems. A bioeconomic model that combines weed biology, crop growth and economics is developed to value the effects of seasonal variability and the role of tactical responses and sequential decision making in determining an optimal integrated weed management strategy. This shows that there are substantial differences in the measured long‐term benefits from deterministic and stochastic simulations. It is concluded that, for research evaluation of technologies that involve complex biological and dynamic systems, ignoring the impacts of seasonal variability, responses to risk and sequential decision making can lead to an incorrect estimate of the economic benefits of a technology. In this case study of optimal weed management strategies in Australia, the size of the error is high.
