What is different about urban activities of those with access to ICTs? Some early evidence from Québec,Canada

The first wave, conducted in 2002–2003, of an in-depth panel survey in Quebec City, was used to compare the out-of-home activities of adults who had the use of mobile phones, or of internet at home, to those who did not. A unique feature of the survey was the inclusion of respondents’ perceptions of the both the temporal and the spatial flexibility of all executed activities. We find, after statistical controls for other factors, that mobile phone use was positively associated with activity and trip levels, while internet access was negatively associated. These two ICTs also had mostly opposite relationships with the routinisation and pre-arrangement of activities and with some conventionally defined sub-classes of activity.     

Banks, markets, and efficiency

A competitive financial system can help reduce banks’ monopoly power and the associated inefficiencies. However, according to Diamond (J Polit Econ 105: 928–956, 1997) and Fecht (J Eur Econ Assoc 6(2), 2004) competition with the financial sector may also constrain the amount of liquidity insurance that banks can provide to households affected by unobservable idiosyncratic liquidity shocks. To study this trade-off, we model competition between banks and between banks and financial markets. Our analysis shows that competition between banks and financial markets can constrain the risk-sharing offered by deposit contracts. This effect is the same if competition between banks mainly affects the reallocation of deposits. However, if banking competition primarily affects new deposits, then such competition only limits inefficient monopoly rents without restraining risk-sharing.

Persistence and Change at the Top of the IT Sector

We use the DATAMATION index of the top 50 domestic IT companies (1975–1995) to track persistence and change at the top of the sector. The trends that we uncover are increasing instability, rejuvenation (declining average age of entrants coupled with increasing average age of quitters), democratization (diminishing revenue inequality at the top) and growing supply‐side intertwining of sub‐sectors and industries within IT due to diversification by long‐term survivors.     

Sampling equilibrium, with an application to strategic voting

We suggest an equilibrium concept for a strategic model with a large number of players in which each player observes the actions of only a small number of the other players. The concept fits well situations in which each player treats his sample as a prediction of the distribution of actions in the entire population, and responds optimally to this prediction. We apply the concept to a strategic voting model and investigate the conditions under which a centrist candidate can win the popular vote although his strength in the population is smaller than the strengths of the right and left candidates.     

International market selection strategies of manufacturing and services firms

This paper discusses the entrepreneurial landscape in Africa and locates a new generation of African entrepreneurs and their business networks within it. Unlike others in that landscape (i.e. micro- or small-scale informal sector vendors, and traditional or multinational large-scale formal sector firms), the ‘new generation’ entrepreneurs are business globalists who organized a system of business enterprise networks consisting of national, regional, and pan-African organizations. The study analyses interview data from 57 men and women network members from 10 countries (Botswana, Ethiopia, Ghana, Kenya, Mali, Senegal, South Africa, Uganda, Zambia, and Zimbabwe). Some defining characteristics of these entrepreneurs are interactive social and business relationships, use of modern management methods and information technology, trust among fellow members, transparent business practices, advocacy on behalf of the private sector, and commitment to increasing intra-African commerce. Their mission is to improve the climate for private sector business in Africa and to promote regional economic integration. They pursue cross-national commercial ventures, maintain official observer status at established regional economic organizations, sign memoranda of understanding with multilateral agencies, establish venture capital funds, and help to change government policies. The paper identifies characteristics of the ‘new generation’ entrepreneurs, evaluates goals and achievements of their networks, and concludes that despite limitations, these entrepreneurs and their organizations have created intra- and cross-national networks that strengthen private-sector-led economic growth in Africa.     

Optimal monetary policy and economic growth

A question at the center of many analyses of optimal monetary policy is, why do central banks never implement the Friedman rule? To the list of answers to this question, we add neoclassical production (specifically, the Tobin effect) as one possible explanation. To that end, we study an overlapping generations economy with capital where limited communication and stochastic relocation create an endogenous transactions role for fiat money. We assume a production function with a knowledge externality (Romer style) that nests economies with endogenous growth (AK form) and those with no long-run growth (the Diamond model). The Tobin effect is shown to be always operative. Under CRRA preferences, a mild degree of social increasing returns is sufficient (but not necessary) for some positive inflation to dominate zero inflation and for the Friedman rule to be sub-optimal, irrespective of the degree of risk aversion.     

The impact of cultural exceptions: audiovisual services trade and trade policy

Audiovisual services such as music and movies in digital formats have gained substantial importance over the last decade, while remaining one of the sectors with the lowest number of commitments by WTO members. Based on a novel data set, this article analyses the role of trade restrictions on audiovisual services in a gravity model. We find that countries with WTO commitments trade more audiovisual services, while both exports and imports are lower for countries which impose policies to curb inflows of foreign cultural services.     

An empirical investigation of interregional production relations and comparative advantage in US manufacturing, 1960–70

Hypothesized differences in mean changes in shares of European Community (EC) import markets over the period 1976-84 are tested for each of 36 less-developed countries. Means are calculated for cases in which MFN tariffs are re-established and for cases in which duty-free treatment is restored under the EC generalized system of preferences. They are compared with means for cases in which tariffs remained constant. We attempt to control for both product-specific and cyclical influences on imports. In contrast to some previous results, our findings suggest that denial (restoration) of preferential treatment, i.e. a tariff increase (decrease), has its expected negative (positive) effect.     

Estimating the Impact of WTO and Domestic Reforms on the Indian Cotton and Textile Sectors: a General-Equilibrium Approach

The agreement to abolish the quotas on textiles and clothing introduced under the Multi‐fiber Arrangement (MFA) will create a new and much more competitive world market for India's exports of textiles and clothing. India's inefficient and costly policies, such as cotton export quotas, the hank yarn obligation, and the restrictive policies on foreign investment that have held back productivity in the Indian apparel sector, will impose serious costs. The authors consider the implications of reforming these policies in an open trading environment using a multiregion, applied general‐equilibrium model. They find that the costs of these policies to India increase substantially following abolition of the MFA; the benefits to India from domestic reforms are considerably enhanced when there is global free trade in textiles and apparel.
