After the famine: food aid policy and management issues in sub-Saharan Africa

The large amount of food aid that was required to meet Africa's emergency food situation resulted in the postponement of some fundamental decisions that were being taken about food aid use in sub-Saharan Africa. Now the donor community and recipient governments are again giving priority to integrating food aid with other available resources in order to meet longer-term food policy and wider development objectives. This paper looks at some of the policy and management issues which need to be addressed if the effectiveness of food aid assistance is to be improved in the current African context. Shortages of locally qualified personnel to administer project food aid have proven to be a major bottleneck in most sub-Saharan countries. Most sub-Saharan states receive food aid from a variety of sources: multilateral, bilateral and a few private-voluntary organizations. As a result, countervailing priorities are set by the donors themselves and give rise to conflicts. The recent drought and famine conditions have compounded an image problem in which food aid is narrowly identified by recipient governments as a project resource to be used primarily for nutrition interventions and for the rural sector. The image problem often limits project selection and overlooks innovative uses of food aid. Many sub-Saharan countries are starting to acquire considerable amounts of counterpart funds from program food aid. However, their use is not coherently integrated with the total aid flow. Multi-year programming has emerged as a management issue which has unnecessarily divided the food aid donor community. The fundamental issue is flexibility in programming, not multi-year programming. The major policy objective now facing the food aid donor community and recipient countries is how to lower emergency allocations while simultaneously increasing project and program aid. Most nonfood-aid donor agencies and their constituent bodies do not treat food aid as a valid economic resource, thereby undermining its effectiveness. The eventual success of food aid use in Africa may be a function of the recipient governments and other major donor and financial organizations.     

Stackelberg price leadership in spatial competition

This paper examines Stackelberg price leadership in a spatially competitive model with infinitely many stores on an infinite line. A Stackelberg price leader charges significantly more than the pure Nash equilibrium price, induces its neighbors to charge somewhat more than the pure Nash equilibrium price, and increases its profits. Under Nash equilibrium, collusion of two stores makes a difference to prices only if the colluding stores are nearest neighbors. Under Stackelberg price leadership, collusion makes a difference to prices even if the stores are not nearest neighbors.     

A Taxonomy of R&D Control Models and Variables Affecting Their Use

This paper provides a discussion of dimensions and variables along these dimensions which are believed to be relevant to the control of R&D. Control models gleaned from the literature are compared and classified into a threedimensional taxonomy of control models. The proposed dimensions and the variables associated with them are:
Focus (i.e. project, related projects, programs);
Technical Effort Measurement (Le. project milestones, program goals, organizational agenda);
Financial Orientation (i.e. expense, capital). Of the eighteen potential control models yielded by the taxonomy, nine were found to be reported in use in the literature.
In addition, the authors hypothesize that organizational history, profitability, structure, task environment, type of research conducted, and hierarchical level of control are important determinants of the type of control employed in organizations. How these factors influence the control variables employed in organizations is hypothesized and discussed.     

Higher Highs and Lower Lows: The Role of Corporate Social Responsibility in CEO Dismissal

Research summary: Investing a firm's resources in corporate social responsibility (CSR) initiatives remains a contentious issue. While research suggests firm financial performance is the primary driver of CEO dismissal, we propose that CSR will provide important additional context when interpreting a firm's financial performance. Consistent with this prediction, our results suggest that past CSR decisions amplify the negative relationship between financial performance and CEO dismissal. Specifically, we find that greater prior investments in CSR appear to expose CEOs of firms with poor financial performance to a greater risk of dismissal. In contrast, greater past investments in CSR appear to help shield CEOs of firms with good financial performance from dismissal. These findings provide novel insight into how CEOs' career outcomes may be affected by earlier CSR decisions. Managerial summary: In this study, we examined a potential personal consequence for CEOs related to corporate social responsibility (CSR). We explored the role prior investments in CSR play when a board evaluates the firm's financial performance and considers whether or not to fire the CEO. Our results suggest that while financial performance sets the overall tone of a CEO's evaluation, CSR amplifies that baseline evaluation. Specifically, our results suggest that greater past investments in CSR appear to (a) greatly increase the likelihood of CEO dismissal when financial performance is poor, and (b) somewhat reduce the likelihood of CEO dismissal when financial performance is good. Thus, striving to deliver profits in a socially responsible manner may have both positive and negative personal consequences. Copyright © 2017 John Wiley & Sons, Ltd.     

Diffusion of mobile telephony: An empirical study in Taiwan

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.     

Riskiness of Real Estate Development: A Perspective from Urban Economics and Option Value Theory

In this article, we define a new construct for urban economic and investment analysis, which revisits the conventional wisdom that investment in real estate development is riskier than investment in stabilized property assets. This new construct, referred as a “development asset value index” (DAVI), is a value index for newly developed properties (only) in a given geographical property market. It tracks longitudinal changes in the highest and best use (HBU) value of locations, and it reveals developer and landowner behavior taking advantage of the optionality inherent in land ownership. In particular, the DAVI reflects developers' use of flexibility in the exercise of the call option to (re)develop the property to any legal use and density. We empirically estimate a DAVI for commercial property (i.e., central locations) and compare it with a corresponding traditional transaction‐price‐based property asset price index (PAPI) corrected for depreciation. We believe that the difference primarily reflects the realized value of flexibility in land development. We find that the DAVIs display greater value growth and are smoother over time and less cyclical than their corresponding PAPIs for the same locations. This suggests that developers successfully use flexibility, and that development may be riskier than stabilized property investment due primarily only to leverage effects (construction costs). Practical implications are also discussed.     

Performance deviations and acquisition premiums: The impact of CEO celebrity on managerial risk‐taking

Research summary: This article draws on identity control theory and a study of acquisition premiums to explore how CEO celebrity status and financial performance relative to aspirations affect firm risk behavior. The study finds that celebrity CEOs tend to pay smaller premiums for target firms, but these tendencies change when prior firm performance deviates from the industry average returns, thereby leading these CEOs to pay higher premiums. The study also finds that the premiums tend to be even larger when celebrity CEOs have more recently attained celebrity status. Taken together, these findings contribute to identity control theory and CEO celebrity literatures by suggesting that celebrity status is a double‐edged sword and that the internalization of celebrity status by CEOs strongly influences the decision‐making of CEOs. Managerial summary: The purpose of this article is to examine how CEO celebrity status and financial performance relative to aspirations affect the size of acquisition premiums. The study finds that celebrity CEOs tend to pay smaller premiums for target firms. However, when celebrity CEOs' prior firm performance is either better or worse than the industry average, these CEOs pay higher premiums. This situation is exacerbated when the CEO has only recently been crowned a celebrity. In effect, these CEOs feel great pressure to match the inflated performance expectations that come with celebrity status. These findings suggest that being a celebrity is a double‐edged sword. The implication here is that CEOs who have recently been crowned a celebrity should be aware of these pressures and cope accordingly. Copyright © 2015 John Wiley & Sons, Ltd.     

Market Conditions and Housing Choices: A Comparison of Homeownership Across Three Decades

This article uses information on out‐of‐pocket housing cost and house price appreciation along with the geo‐coded version of the Panel Study of Income Dynamics to consider the differences in the impact of these and other variables on the tenure choices of sample households across three time periods, the 1970s, the 1980s and the 1990s. Specifically, an extended continuous time probability model is used to examine households' transitions from renting to owning and subsequent possible transitions either back to rental tenure or to another owned home during our three observation periods. Coefficient estimates show that financial variables such as house price appreciation and out‐of‐pocket housing cost play an important role in determining all the transitions. In addition, the analysis demonstrates the interesting result that the cumulative likelihoods of homeownership derived from the model are consistently lower than the probabilities of an initial transition to homeownership from rental tenure during the observation period. Finally, the magnitude and timing of the impact on homeownership of a policy experiment that eliminates the mortgage interest deduction are shown to differ substantially across the three decades.     

The Impact of Second Loans on Subprime Mortgage Defaults

An estimated 12.6% of primary mortgage loans were simultaneously originated with a second loan from 2004 until 2008, although relatively little is known about how the presence of such subordinate loans affects the default decisions of borrowers. We use a novel data series of loan servicing records from 2002 until 2010 to identify such borrowers and find evidence that the default behavior of these borrowers significantly differs from borrowers without second loans. Estimating a discrete‐time proportional odds hazard model, we find borrowers with a second loan were 62.7% more likely to default each month on their primary loan when conditioning alone on the attributes of the primary loan. However, borrowers of second loans were 58.3% less likely to default on their primary loan as compared to single‐loan borrowers with equivalent current combined attributes (i.e., loan‐to‐value, balance and interest rate). We hypothesize and provide empirical evidence that this occurs because borrowers with second loans have the option to sequentially default on each loan since subordinate lenders will not pursue foreclosure if borrowers have insufficient equity. Lenders of defaulted subordinate debt may revisit their decision to foreclose in the future after housing markets start to recover, thus prompting a new round of foreclosures.
