The value of tax benefits and the cost of liquidating versus selling failed thrift institutions

This paper examines the 205 insolvent thrifts that were resolved in 1988 and assesses the cost savings obtained by selling 179 of the institutions through assisted acquisitions rather than liquidating them. It is hypothesized that the cost savings were determined by factors related both to the future viability of the acquired institution and the particulars of the deal arranged by the Federal Home Loan Bank Board and the Federal Savings and Loan Insurance Corporation. The added value by selling a thrift is determined primarily by the level of core deposits obtained by the acquired thrift. However, the branch structure and purchased mortgage-servicing rights should also add franchise value to the firm. In addition to these factors, the analysis accounts for the tax benefits and other regulator forbearances associated with the deals. Other characteristics of the deals are also considered. It is found that core deposits, tax benefits, purchased mortgage-servicing rights, average branch size, and type of acquirer, as well as some other factors, were significant determinants of the cost savings obtained through selling an institution rather than liquidating it.

Estimation of Agricultural Production Functfons on a World-Wide Basis

Agricultural production is becoming increasingly capital and research intensive. Hayami and Ruttan, along with others, have developed and applied the metaproduction functional approach to the examination of this phenomenon on a worldwide basis. Limitations to the approach derive from a restrictive functional form chosen for estimation, and from a restrictive specification of agricultural capital and land. This study addresses those difficulties by use of the flexible translog functional form for estimation and by specifying an overall agricultural capital index and a land measure incorporating differences in the quality of land (agricultural natural resource) endowments. Estimation results indicate that agricultural comparative advantage in production is likely shifting to developed countries relative to LDC's due to capital constraints in the latter. Also agricultural potential (i.e., land endowments) do not serve to differentiate nations on the basis of agricultural production. Investment in agriculture, including land improvement, is key to the determination of comparative advantage. La production agricole fait appelle de plus en plus a beaucoup de re-cherches et de capitaux. Hayami et Ruttan, avec d'autres, ont developpe et appliqué l'approche fonctionnelle métaproduction pour examiner ce phénomena à l‘échelle du monde. Les limitations de cette approache provienneent de la forme fonctionnelle restrictive choisie pour l'estimation, et de la spécification restrictive de capitaux et terres agricoles. Cette étude traite ces difficultés en utilisant la formule “translog’ fonctionnelle adaptable pour l'estimation et en spécificant un indice du capital agricole global et une mesure de terre qui incorpore les différences du qualité des terres agricoles (ressources agricoles naturelles). Tous les résultats estimatifs indiquent que l'avantage comparatif agricole de production s'incline vers les pays développés parraport aux PMD dû aux constraintes de capitaux dans ces derniers. Aussi la capacité agricole (c'est à dire la richesse des sols) ne sert pas à différencier les nations sur le plan de production agricole. L'investissement dans l'agriculte, notamment l'amélioration de terre, est la cief pour déterminer l'avantage comparatif.
