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.     

Sulla nozione di riassunto esaustivo

Si studiano dal punto di vista formale (ponendosi in un quadro astratto molto generale) le relazioni tra la nozione di riassunto esaustivo «in senso classico» e quella di riassunto esaustivo «in senso bayesiano». In particolare si analizzano, per ciascuna di queste nozioni, le condizioni di validità della fattorizzazione di Neyman.

Résumé On étudie d'un point de vue purement formel (en se plaçant dans un cadre abstrait très général) les relations entre la notion de résumé exhaustif «au sens classique» et celle de résumé exhaustif «au sens bayesien».On analyse notamment, pour chacune de ces deux notions, les conditions de validité de la factorisation de Neyman.

Pubblichiamo volentieri questo articolo di G. Letta, che per l'impostazione astratta si allontana alquanto dall'ambito degli interessi scientifici di questa Rivista, perché l'argomento trattato è strettamente legato ad un lavoro di D. M. Cifarelli ed E. Regazzini recentemente comparso sul nostro periodico (vedi [3] e la 2^a parte in questo fascicolo).     

Antithetic variates to estimate the simulation bias in non-linear models

This paper describes a Monte Carlo experiment, which makes use of antithetic variate sampling, to get an accurate estimate of the deterministic simulation bias in the non-linear Klein—Goldberger model. The computational efficiency is more than 500 times greater than in case of simple random sampling.     

The Impact of Trade Liberalization on Enterprises in Small Backward Economies: the Case of Chad and Gabon

This paper examines the impact of trade and fiscal reforms and of the 1994 devaluation of the CFA franc on enterprise development in Chad and Gabon. These reforms provide a natural experiment to assess the impact of trade liberalization in countries with a small and backward manufacturing sector. The empirical analysis is based on a new panel data base covering virtually the whole population of manufacturing firms in Chad and Gabon, and containing data spanning from the year before to two years after the reforms. The paper finds that although firms’ response to changing incentives was non‐negligible, with a shift of output from nontradable to tradable and an increase in productivity, the reform process was unable to generate a virtuous and self‐sustained circle, where export expansion brings a generalized productivity increase which in turn feeds on further export growth.     

Hormone beef, chlorinated chicken and international trade

We study international trade in innovative goods subject to uncertain consumer health effects. Such goods are often at the center of international trade disputes. We show that an interesting form of protectionism may arise because of scientific uncertainty. A free-riding effect is identified, implying more conservative behavior by countries. We also study the role of producers (lobbies) in providing valuable information, finding that the innovative lobby has an advantage in providing information as compared with the lobby producing the ‘traditional’ good. Moreover, lobbies disclose more information when the health effects are long lasting.     

Asset restructuring strategies in bank acquisitions: Does distance between dealing partners matter?

One of the most lively-debated effects of banking acquisitions is the change in lending and asset allocation of the target bank in favour of transaction-based products, at the expense of small and informationally opaque borrowers. These changes may be the result of two distinct restructuring strategies pursued by the acquirer with respect to the asset portfolio of the acquired bank: a cleaning strategy (CS), in which the acquirer makes a clean sweep of all the negative net present value activities in the portfolio of the acquired bank, and a portfolio strategy (PS), in which the acquiring bank permanently changes the portfolio allocation of the acquired bank. In this paper we focus on Italian bank acquisitions and test which asset restructuring strategy was predominantly pursued over the period 1997–2003. Moreover, we distinguish acquisitions according to their geographic diversifying character and to the physical and cultural distances that separate acquiring from acquired banks. When we look at the mean value, we do not find clear evidence of a primacy either of CSs or PSs. When we separate in-market from out-of-market bank acquisitions, however, results show that the CSs prevail only in the former type of deals, while in the latter the portfolio of acquired banks is subject to PSs. Finally, we find that differences in asset restructuring strategies can be explained by differences in corporate culture and the workplace environment of the dealing partners.     

Is Social Security Really Bad for Growth?

This paper develops a model of endogenous growth with overlapping generations to investigate the joint determination of social security, public investment, and growth in a small open economy. We show that a pure pay-as-you-go system with benefits indexed to wages provides taxpayers with incentives to support growth-oriented policies, which increase the future productivity of labor. We find that outcomes characterized by positive levels of intergenerational redistribution, public investment, and long-run growth can be sustained as subgame-perfect Nash equilibria of an infinitely repeated intergenerational game, if and only if the marginal productivity of public capital is large enough. Furthermore, we show that transfers comove with public investment and growth. Journal of Economic Literature Classification Numbers: E62, H55.
