Women Trailblazers in the Statistical Profession

A brief historical introduction to nine women who were trailblazers in the statistical sciences is presented. During their times, men dominated the profession. Yet we see how these women in their various ways blazed trails and as such became mentors and inspirations for generations of women practitioners who worked with them and followed in their footsteps.     

An examination of Peter Drucker's work from an institutional perspective: How institutional innovation creates value leadership

This paper uses an institutional perspective to analyze Peter Drucker's contributions to management, marketing and marketing strategy. Drucker recognizes the importance of institutions in society. Further, his work reflects a variety of institutional views from sociology, economics and marketing. Drucker uses a form of comparative institutional analysis for evaluating both management and strategy issues. At the heart of each institutional comparison is the customer and the value created for the customer by the organization. Institutional comparisons help managers understand how the organization can create customers by adjusting its customer value proposition. Drucker influences marketers by focusing on how the organization's values are used to develop the organization's customer value proposition. Further, it is shown that the organization's values and its customer value propositions are manifested in its transaction rules, termed marketing institutions. Based on Drucker's work, a framework for comparing marketing institutions is introduced: the value leadership framework.

Debt valuation, renegotiation, and optimal dividend policy

The valuation of debt and equity, reorganization boundaries,and firm's optimal dividend policies are studied in a frameworkwhere we model strategic interactions between debt holders andequity holders in a game-theoretic setting which can accommodatevarying bargaining powers to the two claimants. Two formulationsof reorganization are presented: debt-equity swaps and strategicdebt service resulting from negotiated debt service reductions.We study the effects of bond covenants on payout policies anddistinguish liquidity-induced defaults from strategic defaults.We derive optimal equity issuance and payout policies. The debtcapacity of the firm and the optimal capital structure are characterized.     

A Markov model for the term structure of credit risk spreads

This article provides a Markov model for the term structureof credit risk spreads. The model is based on Jarrow and Turnbull(1995), with the bankruptcy process following a discrete statespace Markov chain in credit ratings. The parameters of thisprocess are easily estimated using observable data. This modelis useful for pricing and hedging corporate debt with imbeddedoptions, for pricing and hedging OTC derivatives with counterpartyrisk, for pricing and hedging (foreign) government bonds subjectto default risk (e.g., municipal bonds), for pricing and hedgingcredit derivatives, and for risk management.     

The extent and magnitude of formalin adulteration in fish sold in domestic markets of Bangladesh: a literature review

Bangladesh has been suffering from rampant food adulteration for the last few decades. Dishonest businessmen use formalin illegally as preservative to prevent spoilage and increase shelf‐life of fish. Prolonged consumption of formalin adulterated fish may cause serious health hazards (i.e. cancers) which lead to increased morbidity and mortality. The aim of the review was to examine the extent and magnitude of illegal formalin treatment in fish sold in domestic markets of Bangladesh. A systematic review was conducted using conventional databases and non‐conventional approaches to identify the relevant studies. Out of nine studies, eight confirmed the presence of formalin in fish collected from the markets of four main cities. Large and imported fishes were found to be mainly affected. Formalin adulterated fish was reported in seven studies. The fish were tested using a locally developed kit, and the amount of formalin treated fish ranged between 0.5 and 50%. Two other studies used the spectrophotometric method and reported specific formalin levels. The study conducted in Dhaka found mean levels of formalin to be 402.35 mg/kg in imported fishes and 118.60 mg/kg in local fishes which were much higher than the WHO recommended levels. In another study conducted in Mymensingh, formalin levels ranged between 1.4 and 7.3 mg/kg in both marketed and freshly caught pond fishes. The use of accurate, simple, specific and sensitive techniques is therefore highly recommended. The government and other agencies should address the issue as a priority basis by formulating effective policies and programs to safeguard the health of the public.     

INTEREST GROUPS AND ECONOMIC POLICY: EXPLAINING THE PATTERN OF PROTECTION IN THE BRAZILIAN AGRICULTURAL SECTOR

This article examines the determinants of the pattern of protection across products in the Brazilian agricultural sector from 1969 to 1989. Three key determinants of policy are explored: interest group pressure, government objectives, and structural change associated with economic crisis and a change in political regime. The principal agricultural policies are analyzed, and nominal protection coefficients (NPCs) and producer subsidy equivalents (PSEs) are calculated. When NPCs are used as the dependent variable, econometric results indicate that interest group characteristics such as group size were an important determinant of the pattern of protection. With PSEs, government efforts to raise tax revenues, generate foreign exchange, and control inflation played a more significant role. The results of this paper suggest that future studies of the political economy of protection should pay more attention to the specification of the dependent variable because the conclusions can depend crucially on this choice.     

Intertemporally dependent preferences and the volatility of consumption and wealth

In this article we construct a model in which a consumer's utilitydepends on the consumption history. We describe a general equilibriumframework similar to Cox, Ingersoll, and Ross (1985a). A simpleexample is then solved in closed form in this general equilibriumsetting to rationalize the observed stickiness of the consumptionseries relative to the fluctuations in stock market wealth.The sample paths of consumption generated from this model implylower variability in consumption growth rates compared to thosegenerated by models with separable utility functions. We thenpresent partial equilibrium model similar to Merton (1969, 1971)and extend Merton's results on optimal consumption and portfoliorules to accommodate nonseparability in preferences. Asset pricingimplications of our framework are briefly explored.     

A simple approach to interest-rate option pricing

A simple introduction to contingent claim valuation of riskyassets in a discrete time, stochastic interest-rate economyis provided. Taking the term structure of interest rates asexogenous, closed-form solutions are derived for European optionswritten on (i) Treasury bills, (ii) interest-rate forward contracts,(iii) interest-rate futures contracts, (iv) Treasury bonds,(v) interest-rate caps, (vi) stock options, (vii) equity forwardcontracts, (viii) equity futures contracts, (ix) Eurodollarliabilities, and (x) foreign exchange contracts.     

Fields of opportunity: How marketers design the transaction game with transaction field maps

While the importance of transaction institutions, or rules, has long been established in the area of marketing governance, marketers and academics alike would benefit from guidance in the strategic use of the rules of the transaction game. This is particularly important in B2B and industrial markets where innovations in the rule-making environment have a significant effect on innovation. Strategically, the organization achieves its customer objectives by creating arenas for transacting, termed transaction fields, in which social actors transact. The fundamental argument is that organizations create transaction fields to depict the benefits of transacting to customers. Accordingly, managers must focus on strategic transactions; those that fundamentally change the way that transacting takes place in the transaction field. Using a historical case of the American cotton factor, this research demonstrates how marketers overcome factors that limit transacting by mapping their actions in transaction fields using rules. This specialization may result in the emergence of marketing intermediaries and lead to competitive advantage.
