Labor markets and innovation

We examine the effects on the comparative R&D performance of firms of the different labor market conditions they face. The conditions we consider are the bargaining strength of the unions firms face and the contents of the bargain they negotiate. In particular we consider whether unions can bargain over when new technology is introduced. In the theoretical part of the paper we show that increased union strength can sometimes increase the possibility that a firm will successfully innovate, but that allowing a union to delay the introduction of new technology generally reduces a firm's R&D success. Empirical evidence from the United Kingdom shows that both union strength and the type of bargain that unions undertake have significant impacts on R&D spending.     

Price makers and nonclearing markets

In a recent survey article, Benassy argues that fixprice theory holds the key to incorporating monopoly and monopolistic competition into general equilibrium theory. This paper argues that the opposite is true. Fixprice theory is an impediment to incorporating monopoly into general equilibrium theory. The reason for this is that fixprice theory virtually jettisons Walras's law. It is demonstrated that Walras's law makes the general equilibrium analysis of monopoly very tractable, although it was long thought that monopoly and general equilibrium were incompatible.

Dual labour markets and nominal rigidity

The conventional menu cost framework performs poorly with realisticlabour supply elasticities: the menu costs required for pricerigidity are very high and the welfare consequences of monetarydisturbances are negligible. We show that the presence of duallabour markets greatly improves the performance of the frameworkboth by reducing the minimum effective menu costs and by boostingthe welfare consequences. In addition, the introduction of duallabour markets provides an explanation of procyclical productivityand the shrinking of wage differentials during booms, in linewith stylized facts on business cycles.     

The value of institutions for financial markets: evidence from emerging markets

This paper investigates the value of political institutions for financial markets, using panel data from emerging market countries. We test the hypothesis that changes in political institutions, such as improvements in democratic rights and increased government accountability, have a direct effect on sovereign interest rate spreads. We find that financial markets value institutions over and above the economic and fiscal outcomes these institutions shape. Democracy and accountability generally lower sovereign spreads, political risk tends to increase them, and financial markets view election years negatively.     

Emerging financial markets and early US growth

Studies of early US growth traditionally emphasize real-sector explanations for an acceleration that is evident by the period 1815-1840. Interestingly, establishment of the nation's modern financial structure predated by three decades the transportation improvements and widespread use of water- and steam-powered machinery that are thought to have triggered modernization. We argue that an innovative and expanding financial system, by providing debt and equity financing to businesses and governments as new technologies emerged, was central to early growth and modernization. To test the hypothesis, we employ a set of multivariate time series models that relate measures of banking and equity market activity to investment and business incorporations from 1790 to 1850. The results support the hypothesis of “finance-led” growth. Our new view is at odds with earlier views that emphasize the deficiencies rather than the advantages of the early US financial system.     

Product and destination mix in export markets

This article studies the joint destination and product strategies of exporters, using the universe of export transactions for firms located in Portugal in the period 1995–2005. The article breaks down the annual growth rate of total exports along different margins and details choices made by multi-product, multi-destination firms regarding their export portfolio. In addition, the article looks at similar features for the subsample of new exporters. We find that both the firm-level extensive and intensive margins are important in driving the year-to-year variation in aggregate exports. However, variation over time in the sales of continuing exporters is mainly driven by their sales in continuing destinations. In addition, a product’s export tenure within a firm varies largely across currently exported products in the context of an intense activity of product and destination switching. Moreover, the higher the importance of a product, the more its sales are concentrated in the firm’s top destination. Finally, the article finds that, while continuing exporters enter new markets mainly by selling old products, new exporters access new destinations mainly by exporting new products.     

The Assessment: labour markets and welfare

Rapid and radical changes in the labour markets of developedeconomies have had profound implications for the welfare andwell-being of their citizens. This Assessment argues that thereis still considerable divergence in labour-market processesand outcomes across countries. This is likely to remain thecase. Nevertheless, there is a range of common problems. Importantamong these are what is happening to the rights of people atwork and how they should be protected. Views about appropriaterights have altered in recent years. In the future, debate aboutthis is likely to be even more closely linked to debate aboutlabour-market flexibility. The Assessment goes on to discussa variety of distributional problems related to joblessnessand low pay, and evaluates policy interventions designed totackle them. Although there has been progress in terms of policyeffectiveness, interventions are fragile in helping people toescape from cycles of repeated misfortune and long-term disadvantage.     

Occupation-specific human capital and local labour markets

Most skills acquired through on-the-job training may be specificto an occupation and therefore transferable to some but notall firms. This paper explores the relationship between thesize of the local market for an occupation-specific skill andjob-training outcomes. The Stevens (1994) model of trainingpredicts that as market size increases, job turnover increasesand training becomes more general. I test these predictionsusing data on blue-collar workers and variation in market sizeacross US metropolitan areas. The empirical results supportthe theoretical predictions and the impacts are most relevantat low levels of market size.     

Lead markets, innovation differentials and growth

This article suggests that the specialization of countries in international trade is determined by the lead-lag market pattern of national markets. Many internationally successful innovations have been adopted first in one country while other countries initially either preferred other designs or an established product. A model for the international diffusion of innovations is presented in which nationally preferred innovation designs compete to become a globally dominant design. In this model, there are country-specific market attributes that increase the likelihood that the choice a country makes among alternative technologies is followed around the world. It is argued that technological knowledge gaps are not the origin of an international competitive advantage. Instead, a country gains a competitive advantage because a specific innovation design was adopted earlier than in any other country. This gives local firms a head start in producing, gathering marketing intelligence and securing the property rights of a globally successful innovation. In countries with lag market characteristics, domestic innovations are less likely to get adopted worldwide. Lag markets often switch from a domestic innovation design to a foreign innovation design, which increases imports. The lead-lag market explanation of trade specialization has implications for national policies. In this model domestic innovations do not always foster exports; idiosyncratic innovations induced by lag market contexts can hamper the export chances of local firms and in the end lead to an increase in imports. It is suggested that in order to increase exports, national policies have to distinguish between a domestic lead and lag market context in each industry. While in a lead market context, traditional policy instruments that enhance the rate of innovations are effective, in a lag market situation national follower strategies are more appropriate.     

Russia and the global intellectual services markets

The incipient process of intellectualization of global development is described and the role and behavior of intellectual (nonmaterial) services in the world economic relations is presented. Russia’s position on global nonmaterial service markets is analyzed in comparison with other countries. The scope for utilization of the Russian scientific, educational and other intellectual potential in its foreign economic activities is expounded.     

Financial innovation and European housing and mortgage markets

In this paper we assess the recent history of house prices andof mortgage lending across Europe. We develop a simple economicframework to estimate the likely contributions of fundamentalfactors, such as changes in real incomes and population growth,to house price appreciation. We also try to quantify how muchof price rises might have been driven by rising expectationsof future capital gains. We estimate that this might have playeda significant role in several countries, including Spain, Sweden,Belgium, and the UK. We then consider what different types ofmortgage arrangement might become attractive in a world of higherhouse prices, analysing types of indexed mortgage that haveadvantages where prices are higher relative to incomes and wherehouse prices may be volatile and cannot be assumed to carryon rising.
