On institutional ownership and firm performance: A disaggregated view

We study the relationship between institutional ownership and firm performance in Finland. A systems approach is employed to investigate the potential two-way causality between firm performance and ownership structure. Three-stage least squares estimation technique is used to solve for the systems. The evidence suggests an endogeneity problem between firm performance and institutional ownership. However, the magnitude of the problem differs with respect to the concentration of ownership measure used. Our results show that a more equal distribution of the voting power among the largest institutional stakeholder may exert positive effects on firm performance. We also find a significant difference relating to firm performances and equity ownerships between the two classes of institutional investor. Consistent with the ownership structure in Finland, we find that a simple ownership concentration index does not influence firm performance.     

What do information frictions do?

Summary. We present an overlapping generations model in which a labor market friction (moral hazard) coexists and interacts with a credit market friction (costly state verification). Our main results are: (i) while credit market frictions have long- and short-run real effects, labor market frictions typically have only short-run effects unless they also affect the volume of investment per worker, (ii) the frictions amplify each other to produce higher long-run unemployment than would result from only labor market frictions, (iii) these distortions may prolong the effect of temporary shocks, and (iv) the dynamics of economies with both frictions are qualitatively similar to their frictionless counterparts.Received: 25 February 2003, Revised: 1 April 2004, JEL Classification Numbers: E13, E24, O41, O17.

The non‐monotonic relationship between seigniorage and inequality

Abstract. We present an analysis of how political factors may come into play in the equilibrium determination of inflation. We employ a standard overlapping generations model with heterogenous young‐age endowments, and a government that funds an exogenous spending via a combination of non‐distortionary income taxes and the inflation tax. Agents have access to two stores of value: fiat money and an inflation‐shielded, yet costly, asset. The model predicts that the relationship between elected reliance on the inflation tax (for revenue) and income inequality may be non‐monotonic. We find robust empirical backing for this hypothesis from a cross‐section of countries. JEL classification: E5, P16     

Treatment effect bounds: An application to Swan–Ganz catheterization

We reanalyze data from the observational study by Connors et al. (1996) on the impact of Swan–Ganz catheterization on mortality outcomes. The study by Connors et al. (1996) assumes that there are no unobserved differences between patients who are catheterized and patients who are not catheterized and finds that catheterization increases patient mortality. We instead allow for such differences between patients by implementing both the instrumental variable bounds of Manski (1990), which only exploits an instrumental variable, and the bounds of Shaikh and Vytlacil (2011), which exploit mild nonparametric, structural assumptions in addition to an instrumental variable. We propose and justify the use of indicators of weekday admission as an instrument for catheterization in this context. We find that in our application, the Manski (1990) bounds do not indicate whether catheterization increases or decreases mortality, where as the Shaikh and Vytlacil (2011) bounds reveal that at least for some diagnoses, Swan–Ganz catheterization reduces mortality at 7 days after catheterization. We show that the bounds of Shaikh and Vytlacil (2011) remain valid under even weaker assumptions than those described in Shaikh and Vytlacil (2011). We also extend the analysis to exploit a further nonparametric, structural assumption–that doctors catheterize individuals with systematically worse latent health–and find that this assumption further narrows these bounds and strengthens our conclusions. In our analysis, we construct confidence regions using the methodology developed in Romano and Shaikh (2008). We show in particular that the confidence regions are uniformly consistent in level over a large class of possible distributions for the observed data that include distributions where the instrument is arbitrarily “weak”.     

Trade liberalization and the wage–skill premium: Evidence from Vietnamese manufacturing

This paper examines the wage–skill premium in Vietnamese manufacturing since the reform programme. The effects of tariff reductions on the wage–skill premium are analyzed in the presence of exporting opportunities, foreign investment, and research and development. The findings with firm‐level data reveal that a 10‐ percentage point fall in output tariffs is associated with a 4 percent increase in the wage–skill premium. The wage–skill premium in foreign‐invested enterprises is 40 percent higher than that of domestic enterprises. Trade liberalization influences the wage–skill premium in the presence of foreign ownership and R&D, while its impact on the skill premium only works through exporting.     

The productivity-wage and productivity-employment nexus: a panel data analysis of Indian manufacturing

This article investigates the long-run relationship between labour productivity and employment, and between labour productivity and real wages in the case of the Indian manufacturing sector. The panel data set consists of 17 two-digit manufacturing industries for the period 1973–1974 to 1999–2001. We find that productivity-wages and productivity-employment are panel cointegrated for all industries. We find that both employment and real wages exert a positive effect on labour productivity. We argue that flexible labour market has a significant influence on manufacturing productivity, employment and real wages in the case of Indian manufacturing.     

An exploratory study of RFID adoption in the retail sector

We use a search procedure called content analysis to determine the benefits of RFID in the retail sector. Content analysis classifies textual material, such as academic articles, and reduces them to manageable data. We find that the key RFID retailer benefits are better management of inventory, improved security, better operational efficiency, and reduced cost. We also find the key RFID business processes to deal with, for example, tracking and tracing. Through hypothesis testing and correlations, we discover strong relationships between retailer benefits and RFID business processes, and that better management of inventory is a reason why RFID is being used by retailers.     

A dynamic‐efficiency rationale for public investment in the health of the young

In this paper we assume away standard distributional and static‐efficiency arguments for public health and instead seek a dynamic efficiency rationale. We study a lifecycle model wherein young agents make health investments to reduce mortality risk. We identify a welfare rationale for public health under dynamic efficiency and exogenous mortality even when private and public investments are perfect substitutes. If health investment reduces mortality risk but individuals do not internalize its effect on the life‐annuity interest rate, the “Philipson‐Becker effect” emerges; when the young are net borrowers, this works together with dynamic efficiency to support a role for public health.     

Aging and Productivity Among Judges: Some Empirical Evidence from the High Court of Australia

A number of studies have shown that productivity declines with age in a wide range of activities. Based on United States experience, it has been argued that one profession that might be an exception to this phenomenon is the judiciary. This study explores the relationship between aging and productivity for a sample of retired judges of the High Court of Australia. The High Court provides a useful test for the hypothesis that older judges are more productive because, in contrast to the United States, most, if not all, judges write their own judgments. Thus, ghostwriting does not cloud the issue of judicial productivity. The findings support the life-cycle hypothesis, which suggests the age-citation profile should increase, reach a peak and then decline as judges get closer to retirement. Thus, the results are consistent with the view that the productivity of judges over their working lives follows a similar pattern to other professions such as academia.     

Labour productivity trends in Australian manufacturing: some time series properties

Labour productivity plays a significant role in economic growth, labour demand and employment situation of a particular economy. In this light, the presence of a structural break in productivity, and its unit root property, has important consequences for the overall economy and in major sectors such as manufacturing. In this article, using some recently developed unit root tests, we examine: (i) the null hypothesis of a unit root in the log-level of labour productivity for 38 manufacturing subdivisions against the alternative of trend stationarity over a three-decade period; and (ii) the presence of a structural break in the series, and whether the break has had a permanent or a transitory effect on manufacturing labour productivity. Our main finding is that shocks to labour productivity have had a transitory effect, implying that policies are likely to have only short-term effects.
