How did a network of marine protected areas impact adjacent fisheries? Evidence from Australia

Marine‐protected areas (MPAs) are an effective means of improving habitat quality and biodiversity in the world’s oceans. While the advantages of MPAs as a mechanism for conservation and biodiversity are well established, the potential improvements to fishery performance resulting from a network of MPAs are still being established. Countries around the world have committed to establishing networks of MPAs within their waters by 2020, in response to the United Nations Convention on Biological Diversity. This, coupled with the increasing global demand for seafood and heavy reliance on fishery resources as a source of economic development for many coastal communities, means that an understanding of how these networks can be expected to impact fishery performance is extremely important. We use a difference‐in‐difference modelling approach to isolate the change in the fishery performance associated with the south‐east marine reserve network in Australia. We find no evidence that the economic performance of adjacent fisheries was negatively impacted by the network. This lack of impact is likely due to a network design explicitly intended to avoid effort displacement in key fisheries, along with fishery management changes intended to remove excess fishing capacity.     

R&D and Absorptive Capacity: Theory and Empirical Evidence*

This paper presents a single unified framework that integrates the theoretical literature on Schumpeterian endogenous growth and major strands of the empirical literature on R&D, productivity growth and productivity convergence. Starting from a structural model of endogenous growth following Aghion and Howitt (1992, 1998) , we provide microeconomic foundations for the reduced‐form equations for total factor productivity (TFP) growth frequently estimated empirically using industry‐level data. R&D affects both innovation and the assimilation of others’ discoveries (“absorptive capacity”). Long‐run cross‐country differences in productivity emerge endogenously, and the analysis implies that many existing studies underestimate R&D's social rate of return by neglecting absorptive capacity.     

Annual Review Article 1993: British Public Sector Industrial Relations

Abstract : Developments in public-sector industrial relations during 1993 have raised questions about unions, pay determination and conflict resolution. This review explores some of the tensions in these areas created by new restrictions on pay increases, changes in reward structures and further market-testing across services. Where the different forms of pay determination buy industrial peace, the price may be too high in terms of the productivity and efficiency requirements gains now being demanded. But co-operation is needed too, and the dilution of the Whitley system of collective bargaining may be more likely to produce the very co-operation embodied in its philosophy, but not always present in its practice. The new 'superunion' UNISON will play a role here, as single-table bargaining and even single-union deals develop. These institutional developments will also be affected by pay flexibility measures which endeavour to improve individual performance at the front line of services, while in practice increasingly giving the rewards to management.     

From consensus to fragmentation: The dynamics of paradigm change in Israel

This paper reports on the evolution of spatial planning approaches in Israel with emphasis on the relationship between planning and ideology. The major characteristics of planning studied are: (1) the role of planning; (2) the planning process and methodology; (3) the problems and goals of planning; (4) planning concepts at the national and regional level. The main findings of the research identify four major periods which represent phases in the process of paradigm change: the phase of Grand-Ideas, the phase of Action, the phase of Professionalization, and finally the phase of Ad-hocism. The development of these phases is related to geopolitical changes, socio-economic conditions, the social climate, and the planners' background. These phases are examined in the light of the theoretical framework proposed by Kuhn concerning the development of scientific paradigms.     

Repeat‐Sales Indexes: Estimation without Assuming that Errors in Asset Returns Are Independently Distributed

This article proposes an alternative specification for the second stage of the Case‐Shiller repeat‐sales method. This specification is based on serial correlation in the deviations from the mean one‐period returns on the underlying individual assets, whereas the original Case‐Shiller method assumes that the deviations from mean returns by the underlying individual assets are i.i.d. The methodology proposed in this article is easy to implement and provides more accurate estimates of the standard errors of returns under serial correlation. The repeat‐sales methodology is generally used to construct an index of prices or returns for unique, infrequently traded assets such as houses, art and musical instruments, which are likely to be prone to exhibit serial correlation in returns. We demonstrate our methodology on a data set of art prices and on a data set of real estate prices from the city of Amsterdam.     

Why is Productivity so Dispersed?

Many papers have documented wide variations in productivityeven in narrowly defined industries. Some have argued that thisprimarily reflects measurement problems due, for example, tocomparing across different products. Others argue that thisreflects persistent differences in performance due, for example,to management. This paper looks at productivity differencesnot within an industry but within a firm. We use data on productivityof different branches within lines of business of a major UK-basedwholesaler. Using these productivity data for comparisons is,we argue, more likely to compare like with like than comparingbetween firms. We document sustained differences in productivityeven between branches within the same line of business. We alsodiscuss the extent to which they are correlated with differencesin management and find that such differences ‘account’for around 40 per cent of the difference in productivity.

Immigrant Entrepreneurship in an Emerging Economy: The Case of Turkey

This paper examines motivations for, and paths to, entrepreneurship among immigrants in Turkey based on interviews with 22 immigrant entrepreneurs in Istanbul. Findings suggest that immigrant entrepreneurs in a developing economy may be different from their counterparts in well‐established economies. First, immigrant entrepreneurs rely on their unique human and social capital in the process of starting businesses thanks to their ability to identify opportunities based on insider knowledge of the market in their home and host countries. Second, their ability to foster trusting relationships thanks to language, cultural, and religious knowledge permits immigrant entrepreneurs in an emerging economy to engage in less economically marginal activities.     

The role of incentives and communication in strategic alliances: an experimental investigation

This paper experimentally examines the determinants of the deviation between potential and realized value creation in strategic alliances. To better understand how decision making in alliances may influence success, we use an experimental design that juxtaposes two important factors that affect alliance members' decisions: economic incentives and communication. The evidence from our experiment sheds light on the relative impact of each, and more importantly, how both factors interact to explain successful outcomes. Copyright © 2009 John Wiley & Sons, Ltd.
