Squatting as a transition problem in South Africa

This paper applies principles of transition to land tenure and squatting in South Africa. Political transition in South Africa reassigned political property rights, which produced contestable, and rent‐seeking incentives for squatting as a means to privatize land and redistribute wealth. Government failure to establish and protect private property rights in a squatter camp resulted in common‐pool problems that resisted private and public resolution with consequent rent dissipation and social loss. In response to this retreat from duty, informal agents emerged to claim their own share of the prize. Without enforceable rules of capture, the growth of squatter camps in South Africa will continue.

Greenmail premia, board composition and management shareholdings

This paper investigates the association between premia paid in targeted share repurchases (greenmail) and the characteristics of the boards of directors. A nonlinear relationship is found between the premium paid and the proportion of shares held by the inside directors. The premium decreases as the proportion of unaffiliated outside directors increases.     

Business and national priorities for industrial development: Intersectoral consensus in Israel

This study describes a survey of experts chosen from Industry, Labour, and Government in Israel, who ranked and scored three business and four national goals in the context of industrial development. The business goals represented profitability, capital use and growth potential. The national goals involved human resource utilization, added value, foreign exchange conservation, and export of technologically advanced products. The findings support a hypothesis of consensus on goals and goal priorities between different sectors of the Israel economy, despite what might appear to be their divergent special interests. The findings also indicate overall consensus with respect to a balance between business and national goals. The study concludes that this consensus is the result of the need to respond to environmental threats and uncertainties which has created a sense of mutual interdependence among the sectors.     

Enumeration of Nash equilibria for two-player games

This paper describes algorithms for finding all Nash equilibria of a two-player game in strategic form. We present two algorithms that extend earlier work. Our presentation is self-contained, and explains the two methods in a unified framework using faces of best-response polyhedra. The first method lrsnash is based on the known vertex enumeration program lrs, for “lexicographic reverse search”. It enumerates the vertices of only one best-response polytope, and the vertices of the complementary faces that correspond to these vertices (if they are not empty) in the other polytope. The second method is a modification of the known EEE algorithm, for “enumeration of extreme equilibria”. We also describe a second, as yet not implemented, variant that is space efficient. We discuss details of implementations of lrsnash and EEE, and report on computational experiments that compare the two algorithms, which show that both have their strengths and weaknesses.
