Exotic Passport Options

The Vanilla Passport Option is an insurance against trading loss. In this paper, we add various exotic features to the Vanilla contract and price the resulting financial products. The assumptions that we make are the same as the Black-Scholes ones and the resulting pricing equations are Hamilton-Jacobi-Bellman type equations or parabolic free boundary PDE's which can be solved via finite difference methods.     

Inter-organizational communication as a relational competency: Antecedents and performance outcomes in collaborative buyer–supplier relationships

Inter-organizational communication has been documented as a critical factor in promoting strategic collaboration among firms. In this paper, we seek to extend the stream of research in supply chain management by systematically investigating the antecedents and performance outcomes of inter-organizational communication. Specifically, inter-organizational communication is proposed as a relational competency that may yield strategic advantages for supply chain partners. Using structural equation modeling, we empirically test a number of hypothesized relationships based on a sample of over 200 United States firms. Our results provide strong support for the notion of inter-organizational communication as a relational competency that enhances buyers’ and suppliers’ performance. Implications for future research and practice are offered.     

The asymmetric information and price manipulation in stock market

The interaction between asymmetrically informed traders has been mostly investigated in theoretical frameworks. Not only there are relatively few empirical studies but, if any, the mostly focus on cross-sectional analysis and use very short samples. In this study, we blend theoretic with empirical, and propose a new signalling system of turning points in the economy to examine the extent of volatility of these markets relative to their tranquil periods. The signalling system proposed here is based on the Markov-switching model. Differing from the existing literatures, the study employs three phases and time-varying transition probability, and captures the states of volatility. After examining the causality between high volatility and foreign portfolio investment (FPI) by using moving average and generalized autoregressive conditional heteroskedasticity, the portfolio's profitability of FPI and individual investors in different periods are compared. Finally, the investigation of FPI's leading effect is studied.     

Joint pricing and design of urban highways with spatial and user group heterogeneity

This paper addresses the joint optimization of capacity investments and toll charges imposed on multi-group users in monopolistic private highways within general road networks. A game-theoretic formulation is provided that leads to a nonconvex bilevel program. The proposed modeling framework handles several complex issues raised in realistic applications, such as regulations on the levels of tolls and service, and the discrete nature of highway capacity, using a genetic optimization technique. Real-application results show the importance of considering the spatial heterogeneity of prices, and the tradeoff between investments and pricing strategies in regulated private highways.     

An even simpler differential demand system

Keller (1984) proposed three simple variants of the well-known Rotterdam demand model. This paper proposes an even simpler differential demand system which has some attractive properties and is easy to estimate. The new model is estimated with Dutch and British data.     

Strategic and Marketing Implications of Consumer Behaviour in Financial Services

As competitive liberalisation and the application of technology in the creation and distribution of financial services have increased consumer choice in the UK personal financial service industry, so consumer choice in the UK personal financial services industry, so consumer behaviour has assumed a greater role in determining the strategic environment in which financial service providers operate. This paper explores the reltionship between consumer behaviour and the strategic choices facing financial consumer behaviour and the strategic choices facing financial service firms by developing a framework of consumer behaviour and linking the forms of behaviour and type of financial service instrument that determines the strategic environment within which financial service providers operate. Based on that interaction the paper develops a contingency view of financial services strategy and argues that to be successful, financial service providers will need to move away from broad service provision and adopt more focused strategies that reflect far more closely the strategic environment in which they operate.     

Criminalizing price-fixing

We assess whether recent US Department of Justice (DOJ) price-fixing cases exhibit characteristics that are associated theoretically with optimal use of criminal law. We take our welfare standard from seminal work on optimal legal design. Optimal legal design recognizes the private and public elements present in all areas of the law. The mixed results show that the characteristics to be expected in criminal cases are not all present in the DOJ cases. Criminal sanctions applied in these collusive antitrust cases do however show significant responsiveness to some of the variables derived from the economic analysis of criminal law.     

Are medium‐scale farms driving agricultural transformation in sub‐Saharan Africa?

This study presents evidence of profound farm‐level transformation in parts of sub‐Saharan Africa, identifies major sources of dynamism in the sector, and proposes an updated typology of farms that reflects the evolving nature of African agriculture. Repeat waves of national survey data are used to examine changes in crop production and marketed output by farm size. Between the first and most recent surveys (generally covering 6 to 10 years), the share of national marketed crop output value accounted for by medium‐scale farms rose in Zambia from 23% to 42%, in Tanzania from 17% to 36%, and in Nigeria from 7% to 18%. The share of land under medium‐scale farms is not rising in densely populated countries such as Kenya, Uganda, and Rwanda, where land scarcity is impeding the pace of medium‐scale farm acquisitions. Medium‐scale farmers are a diverse group, reflecting distinct entry pathways into agriculture, encouraged by the rapid development of land rental, purchase, and long‐term lease markets. The rise of medium‐scale farms is affecting the region in diverse ways that are difficult to generalize. Findings indicate that these farms can be a dynamic driver of agricultural transformation but this does not reduce the importance of maintaining a clear commitment to supporting smallholder farms. Strengthening land tenure security of local rural people to maintain land rights and support productivity investments by smallholder households remains crucial.
