Raising the bar (11)

This editorial summarizes the papers published in issue 14(2) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper deals with past and current challenges for regional science research. The second paper investigates whether people living in deprived neighbourhoods have less chance of succeeding in a job application. The third paper finds evidence that real estate firms can avoid price competition when market shares of their allies increase in the vicinity. The fourth paper is methodological: it considers a spatial autoregressive (SAR) model with heterogeneous coefficients and extensively analyzes the impact of this extension on the direct and indirect effects estimates. The fifth paper proposes an innovative method to estimate the elements of the spatial weight matrix in a spatial econometric model. The final paper is econometric–theoretical: it proposes a new generalized method of moments (GMM) estimator of the coefficients of a SAR model if the error terms are heteroskedastic of an unknown form.     

Economic policy uncertainty and firm tax avoidance

We find strong evidence that firms reduce cash effective tax rate when economic policy uncertainty heightens. Firms also engage in more aggressive forms of tax avoidance including long-term tax planning or shelters. Cash holdings attenuate the negative effect of policy uncertainty on cash effective tax rate, especially for financially constrained firms. The cash tax savings are retained for reinvestments rather than dividend payouts. Our findings suggest that policy uncertainty exacerbates external financing frictions, which in turn induces precautionary motives of tax avoidance.     

THE ART OF STRATEGIC DIVESTMENT

Divestiture makes sense only as part of a sound, long-term strategy. Before simply shedding business units, companies must consider all the options, and be willing to constantly review, replenish, and trim portfolios as markets change and evolve. In so doing, a company increases not only its flexibility but also its chances of adding shareholder value.
This article examines the corporate restructuring "big picture," in which divestments are only one alternative. It reviews additional measures besides divestments, such as outsourcing, joint ventures, asset swaps, and using new technologies to cut costs, and provides case studies of each. It also raises some interesting issues regarding divestiture, such as ways to sell a business unit without strengthening a competitor's hand, as well as strategies for improving a business unit's valuation in preparation for sale. The authors, who are M&A advisors at Accenture, conclude that "a carefully planned and well-executed restructuring that involves divestiture can be as significant a victory for management and shareholders as a successful acquisition."     

Rural Informal Taxation in China： Historical Evolution and an Analytic Framework

The present paper examines the historical evolution of China's rural taxation system from the pre-reform period to the late 1990s. We propose that because of information asymmetry between the upper-level and the lower-level governments, local governments had to be granted some informal tax autonomy to fulfill the upper-level policy mandates. This easily led to excessive local informal taxation on farmers. As market liberalization of the grain sector progressed, the low-cost tax instruments implemented through the traditional approach of implicit taxation gradually eroded. Local governments in agricultural regions had to resort to informal fees collected directly from individual rural households while the more industrialized regions shifted to non-agricultural taxes that are less costly in terms of tax collection. Hence, political tension between farmers and local governments in agriculture- based regions emerged and rural tax reform became necessary.     

Management priorities and management ethics

The management process affects the level of ethical performance in organizational life. As one part of this process, managers establish priorities which give direction to an organization. In business firms, management typically stresses the attainment of profits and other related economic and technical factors. Since little explicit recognition is given to ethics, the resulting climate makes it easy to ignore ethical factors. Changing this situation by making ethics a significant part of the corporate culture is difficult and requires a combination of management communication and management example. However, managers who choose to emphasize ethics and who skillfully articulate their importance can improve the integration of ethics into the day-to-day operating decisions of the firm. Justin G.

Inter- and Intra-Organizational Knowledge Transfer: A Meta-Analytic Review and Assessment of its Antecedents and Consequences

abstract    Research on organizational knowledge transfer is burgeoning, and yet our understanding of its antecedents and consequences remains rather unclear. Although conceptual and qualitative reviews of the organizational knowledge transfer literature have emerged, no study has attempted to summarize previous quantitative empirical findings. As a first step towards that goal, we use meta-analytic techniques to examine how knowledge, organization and network level antecedents differentially impact organizational knowledge transfer. Additionally, we consolidate research on the relationship between knowledge transfer and its consequences. We also demonstrate how the intra- and inter-organizational context, the directionality of knowledge transfers, and measurement characteristics moderate the relationships studied. By aggregating and consolidating existing research, our study not only reveals new insights into the levers and outcomes of organizational knowledge transfer, but also provides meaningful directions for future research.     

A tale of two prices: Liquidity and asset prices in multiple markets

This paper investigates the liquidity effect in asset pricing by studying the liquidity–premium relationship of an American depositary receipt (ADR) and its underlying share. Using the [Amihud, Yakov, 2002. Illiquidity and stock returns: cross-section and time series effects. Journal of Financial Markets 5, 31–56] measure, the turnover ratio and trading infrequency as proxies for liquidity, we show that a higher ADR premium is associated with higher ADR liquidity and lower home share liquidity, in terms of changes in these variables. We find that the liquidity effects remain strong after we control for firm size and a number of country characteristics, such as the expected change in the foreign exchange rate, the stock market performance, as well as several variables measuring the openness and transparency of the home market.     

Numerical methods for dynamic Bertrand oligopoly and American options under regime switching

Bertrand oligopolies are competitive markets in which a small number of firms producing similar goods use price as their strategic variable. In particular, each firm wants to determine the optimal price that maximizes its expected discounted lifetime profit. The oligopoly problem can be modeled as nonzero-sum games which can be formulated as systems of Hamilton–Jacobi–Bellman (HJB) partial differential equations (PDEs). In this paper, we propose fully implicit, positive coefficient finite difference schemes that converge to the viscosity solution for the HJB PDE from dynamic Bertrand monopoly and the two-dimensional HJB system from dynamic Bertrand duopoly. Furthermore, we develop fast multigrid methods for solving these systems of discrete nonlinear HJB PDEs. The new multigrid methods are general and can be applied to other systems of HJB and HJB-Isaacs PDEs arising from American options under regime switching and American options with unequal lending/borrowing rates and stock borrowing fees under regime switching, respectively. We provide a theoretical analysis for the smoother, restriction and interpolation operators of the multigrid methods. Finally, we demonstrate the effectiveness of our method by numerical examples from the dynamic Bertrand problem and pricing American options under regime switching.     

The Arduous Journey of Private Labels: Insights From the South African Market and Further Afield

This article presents an overview of private label brands (PLBs) by considering both the status quo and emergent trends in this sphere. The initial focus is profiling private labels in the country of South Africa, with developments from abroad then being juxtaposed against the local retail landscape. Global market trends are brought to the fore at the end of the article. PLB adoption in South Africa currently sits at a paltry 18% (little moved in the last 5 years), compared with a European average penetration rate of 30%. The reasons for this lackluster growth are varied, with a lack of retailer R&D at the root cause. Yet the conditions are right for rapid growth of this merchandise should household incomes continue to remain under pressure and should consumers fully appreciate the value proposition of such brands. Furthermore, it is expected that the global share of the market will reach 50% by 2025 (double that presently) with retailers abandoning B-brands and replacing these with their own substitute PLBs.     

The Revival of Private Landlords in Britain’s Post-Homeownership Society

Homeownership has been declining in favour of private renting in most developed English speaking countries since the early-2000s. Public debates in countries like Britain, Australia and the US have subsequently focused on the ostensible coming of age of ‘generation rent’, constituted of younger individuals excluded from home buying and traditional routes to housing asset accumulation. While the focus of this paper is the significance of access to housing assets as a means to offset potential economic and welfare precarity, our concern is landlords rather than tenants. Drawing on British survey data, we show that the rental boom has been accompanied by increasing multiple property ownership among classes of largely middle-aged and relatively affluent households. Over one-million small-time landlords have emerged in the last decade alone, who, we argue, are part product of historic developments in housing markets and welfare states. Generations of British have not only been orientated towards their homes as commodity assets, they have also begun to mobilise around multi-property accumulation in a context of shifting welfare and pension expectations.
