Changes in Assortative Matching and Inequality in Income: Evidence for the UK*

The extent to which like-with-like marry is important for inequality as well as for the outcomes of children who result from the union. In this paper, we present evidence on changes in assortative mating and its implications for household inequality in the UK. Our approach contrasts with others in the literature in that it is consistent with an underlying model of the marriage market. We argue that a key advantage of this approach is that it creates a direct connection between changes in assortativeness in marriage and changes in the value of marriage for the various possible matches by education group. Our empirical results do not show a clear direction of change in assortativeness in the UK between the birth cohorts of 1945–54 and 1965–74. We find that changes in assortativeness pushed income inequality up slightly, but that the strong changes in education attainment across the two cohorts contributed to scale down inequality.     

Property Rights,Governance, and Economic Development

In this review article we give an intuitive account of why good institutions in general, and secure property rights in particular, matter for economic growth and development. We also discuss implications for good governance, defined as the efficient provision of property rights and other aspects of governance. Finally, we briefly touch on political institutions that might be conducive to good governance and thus economic development.     

INNOVATING GLOBALLY

Costas Markides has spent over two decades studying business strategy and innovation. Recently, he has been focusing on the bigger picture of how people can address major social problems. Can the techniques used by managers to create innovation inside organizations work with global change? Markides talks with Stuart Crainer about his latest research.     

A model of exchange rate policy: evidence for the US dollar–Greek drachma rate 1975–87

This paper represents an attempt to model movements of the exchange rate between the US dollar and Greek drachma. A stuctural model is set up, and then a reduced-form error correction(EC) speicifcation is derived. On the basis of co-integration test, the results do not support the existence of al long-run equilibrium relationship between the exchange rate and price differential. Furthermore, the instrumental variable estimation of the EC model indicates that the monetary authorities have pursued a short-run anti-inflationary exchange rate poilicy that appreciates the exchange rate in the presence of wage inflation as an attempt to mitigate the depreciating pressures on the domestic currency and thus to ease the adjustment required on Greek producers.     

Factors determining municipal broadband strategies across Europe

Recognizing that high-speed broadband connectivity emerges as a key element for growth, city authorities engage in fiber access deployments to empower their local communities in the digital economy. Currently, a growing number of municipal fiber projects are underway or planned while the international community and the telecommunications industry are yet undecided about the role and type of municipal intervention. This paper takes a holistic view of municipal broadband in Europe, aiming to understand the factors that determine municipal strategies in fixed Next-Generation Access (NGA) networks and the implications of municipal broadband to regulation and markets. The data suggests that the determining factors are (a) the engagement of public utilities; (b) the involvement of the private sector in joint infrastructure projects; (c) the local demand for retail and wholesale services; and (d) the institutional and regulatory framework at the European and national scale. The findings of the study indicate that (a) municipal initiatives are highly dependent on national factors, thus the resulting interventions fare strong resemblance within a single country, while they can be substantially different across national contexts; (b) current EU provisions for public involvement in broadband development stimulate municipal plans for large scale arrangements; and (c) national regulatory frameworks, that primarily address vertical integrated incumbents and nationwide markets, may need adjustments to handle emerging access monopolies of regional and city broadband infrastructures.     

Banks’ lending behavior and monetary policy: evidence from Sweden

The main purpose of this paper is to investigate the aggregate data about bank loans which may hide significant information about the monetary transmission mechanism. This study, by disaggregating bank loans data and using the relevant interest rates in Sweden, investigates the behaviour of banks after a monetary policy tightening. By using an unrestricted VAR model and impulse response analysis, our results show that a shock on the policy rate affects the main components of the banks’ loan portfolios differently. Initially, banks do not reduce lending to firms and households and they present a sluggish reaction concerning the relevant interest rates. On the contrary, they reduce lending to mortgage credit institutions significantly since real estate lending can be considered as a risky long-term investment. Moreover mortgage credit institutions reduce lending for housing purposes to non-bank public. This reduction is mainly driven by flexible rate loans and loans secured on tenant owned apartments. Consequently, theses actions have a significant effect on real economic activity, by amplifying the initial shock from the tightening monetary policy. The latter result provides evidence of the bank lending channel in Sweden working via mortgage lending and could be very important for policy makers.     

Dynamic relations of uncertainty expectations: a conditional assessment of implied volatility indices

This study examines the spillover effects in international financial markets with respect to implied volatility indices. The use of the latter as the basis of integration analysis means that we test market participants’ expectations and not the actual price fluctuations. The empirical analysis, which includes all publicly available implied volatility indices, employs the dynamic conditional correlation model of Engle (2002) and its findings suggest that there is significant integration of investors’ expectations about future uncertainty. Furthermore, by accounting for the dynamic volatility of implied volatility inter-dependencies, we are able to reveal possible shifts in conditional correlations of market expectations over time. More specifically, our findings show a slight increase in the conditional correlations for all the volatility indices under review over the years and prove that in periods of turbulence in the financial markets the conditional correlations across implied volatility indices increase.     

Human Capital Investment: The Returns from Education and Training to the Individual,the Firm and the Economy

This paper provides a non-technical review of the evidence on the returns to education and training for the individual, the firm and the economy at large. It begins by reviewing the empirical work that has attempted to estimate the true causal effect of education and training on individual earnings, focusing on the recent literature that has attempted to control for potential biases in the estimated returns to education and training. It then moves on to review the literature that has looked at the returns from human capital investments to employers. Lack of suitable data and methodological difficulties have resulted in a paucity of studies that have carried out sound empirical work on this issue. In the final part of the review, we look at the work that has tried to assess the contribution of human capital to national economic growth at the macroeconomic level. This work has generally involved using either a ‘growth accounting’ theoretical framework or ‘new growth’ theories. Although the empirical macroeconomic evidence that accompanies this work does not generally allow one to distinguish between the two approaches, there is a substantial body of evidence on the contribution of education to economic growth.     

The Changing Distribution of Male Wages in the U.K.

This paper uses microeconomic data from the U.K. Family Expenditure Surveys (FES) and the General Household Surveys (GHS) to describe and explain changes in the distribution of male wages. Since the late 1970s wage inequality has risen very fast in the U.K., and this rise is characterized both by increasing education and age differentials. We show that a large part of the changes in the U.K. can be summarized quite simply as increases in eduction differentials and a decline of growth of entry level wages which persist subsequently. This fact we interpret as cohort effects. We also show that, like in the U.S., an important aspect of rising wage inequality is increased within-group wage dispersion. Finally we use the GHS to evaluate the role of alternative education measures.     

Private information, money, and growth: Indeterminacy, fluctuations, and the Mundell-Tobin effect

We introduce an informational asymmetry into an otherwise standard monetary growth model and examine its implications for the determinacy of equilibrium, for endogenous economic volatility, and for the relationship between steady-state output and the rate of money growth. Some empirical evidence suggests that, for economies with low initial inflation rates, permanent increases in the money growth rate raise long-run output levels. This relationship is reversed for economies with high initial inflation rates. Our model predicts this pattern. Moreover, in economies with high enough rates of inflation, credit rationing emerges, monetary equilibria become indeterminate, and endogenous economic volatility arises.
