A Private-Sector Perspective

The Public-Private Partnership model is best placed as a means for delivering public infrastructure for government. However, the private sector needs to consider some issues if it is to encourage governments to use this model effectively. Specifically, for the public-private partnership model to be sustained and accepted by governments, the private sector needs to explain its benefits in a way that wins the trust of the community.     

Modeling the International-Trade Network: a gravity approach

We investigate whether the gravity model (GM) can explain the statistical properties of the International Trade Network (ITN). We fit data on trade flows with a GM using alternative estimation techniques and we build GM-based predictions for the weighted topological properties of the ITN, which are then compared to the observed ones. Our exercises show that the GM: (i) may replicate part of the weighted-network structure only if the observed binary architecture is kept fixed; (ii) is not able to explain higher-order statistics that, like clustering, require the knowledge of triadic link-weight topological patterns, even if the binary structure perfectly replicates the observed one; (iii) performs very badly when asked to predict the presence of a link, or the level of the trade flow it carries, whenever the binary structure must be simultaneously estimated.     

Lost in transition?

Using data for Germany and 23 other economies in Eastern and Western Europe, this paper estimates the monetary returns to education acquired under communism more than 10 years after the fall of the Berlin Wall. We show that, in the 2000s, Eastern European workers who completed their education under communism earned in the 2000s similar returns to their education as did workers belonging to the same age cohorts who studied in Western Europe. This might suggest that education under communism is still as valuable as education attained in Western Europe. However, individuals educated under communism are more likely than their Western counterparts to be unemployed, retired or disabled, and therefore to earn lower or zero returns to their education. Moreover, when we allow the returns to pre‐ and post‐secondary education to differ, we find that senior males who have attained only primary or secondary education under communism are penalized in the post‐transition Eastern European labour markets, and that those who have completed post‐secondary education under communism enjoy in these markets higher payoffs to their education than similarly educated Western European individuals who are employed in the West.     

Interest rate co-movements, global factors and the long end of the term spread

The decoupling of US short and long interest rates has been a distinctive feature of the 2000s. We employ recent advances in panel econometrics to document this disconnect for industrial countries and link it to a global latent factor in long term rates. We investigate whether international forces, such as global inflation, global output, or the global savings glut may be behind this global latent factor. The savings glut is the most likely contender, suggesting that reserve accumulation and a search for yield from emerging markets has lowered long rates internationally, driving a wedge between domestic short and long rates.     

Institutional constraints on organizations: the case of Spanish car dealerships

We study the effect of organizational choice and institutions on the performance of Spanish car dealerships. Using outlet‐level data from 1994, we find that vertically integrated dealerships showed substantially lower labor productivity, higher labor costs and lower profitability than franchised ones. Despite these gaps in performance, no vertically integrated outlet was separated until 1994, yet the few outlets that were eventually separated systematically improved their performance. We argue that the conversion of integrated outlets into franchised ones involved significant transaction costs, due to an institutional environment favoring permanent, highly unionized employment relations. In line with this argument, we find that the observed separations occurred in distribution networks that underwent marked reductions in worker unionization rates, following the legalization of temporary labor contracts.

A Schumpeterian model of investment and innovation with labor market regulation

Theoretical and empirical models provide ambiguous responses on the relationship between labor market regulation, innovation and investment. On the one hand, labor market regulation increases firms' adjustment costs and, ceteris paribus, decreases investment. But, on the other, it also stimulates firms to invest, innovate, increase productivity and profit in the long run. In this paper we present an endogenous growth model that describes the role of these opposite forces, and why a stricter labor market regulation may positively affect innovation and investment in the long run. Most of the theoretical and empirical results hold for Italy, Germany, France, and Spain.     

Corporate Codes of Ethics,National Culture,and Earnings Discretion: International Evidence

This study examines the role of codes of ethics in reducing the extent to which managers act opportunistically in reporting earnings. Corporate codes of ethics, by clarifying the boundaries of ethical corporate behaviors and making relevant social norms more salient, have the potential to deter managers from engaging in opportunistic financial reporting practices. In a sample of international companies, we find that the quality of corporate codes of ethics is associated with higher earnings quality, i.e., lower discretionary accruals. Our results are confirmed for a subsample of firms more likely to be engaging in opportunistic reporting behavior, i.e., firms that just meet or beat analysts’ forecasts. Further, codes of ethics play a greater role in reducing earnings management for firms in countries with weaker investor protection mechanisms. Our results suggest that corporate codes of ethics can be a viable alternative to country-level investor protection mechanisms in curbing aggressive reporting behaviors.     

Money, expectations, and interest rates

This paper employs a model of nominal interest rate determination in a framework of rational expectations of inflation. Hypotheses are developed with respect to relative impacts of predictable and unpredictable changes in money supply. These hypotheses are tested using quarterly Italian data from 1966–1975. The nominal monetary base is the measure of money employed and one private and two government bond rates measure nominal interest rates. The results are insensitive to variations in estimation procedure and specification of adjustment processes (and even predictive functions for the monetary base). The rational expectations formulation is well supported in every case.
