Robustness to the unavailability of data in block designs

We present general results for finding or boundingt _maxB , the maximum number of arbitrary whole blocks of observations which can be removed from a block design, and still leave all of the elementary treatment contrasts estimable. The block sizes may be larger than the number of treatments. The results are applied to BBDs, reinforced BIBDs and BBDs, BTIBDs, and a series of variance balanced incomplete block designs with two block sizes. Also given for most of these designs, are results fort _max, the maximum number of arbitrary, scattered observations that can become unavailable, and still leave all of the elementary treatment contrasts estimable.The work was undertaken while Dr. Whittinghill was visiting Ohio State University, and supported by a grant from the Natural Sciences Division, Colby College, Waterville, Maine.     

Employee benefit packages for part-time workers

To successfully recruit and retain part-time workers in the decade ahead, managers will need to design more attractive employee benefit packages. This article examines which benefits part-time workers receive and value the most and which benefits they would like to receive.     

Why is bank debt senior? A theory of asymmetry and claim priority based on influence costs

This theory can explain why bank debt is universally senior,consistent with the presence of conflict (lawyers) and absolutepriority violations in financial distress: Better organizedbanks would more strongly contest priority in financial distressif they were junior. Because 'deterrence' can reduce creditors'total expenses in a priority contest, the ex post stronger lobbyist/litigantshould be senior ex ante. For equivalent reasons, the theorycan advise when public debt should be senior to trade creditand/or implicit contrasts, and can even suggest one rationalefor the absolute priority rule (APR). This article further showsthat Chapter 11 creditor reimbursement procedures can loweroverall costs.     

Did Leaving the Gold Standard Tame the Business Cycle? Evidence from NBER Reference Dates and Real GNP

Cover and Pecorino (2005) claim that the March 1933 departure from the gold standard is the most probable break point ushering in an era of longer U.S. expansions, both absolutely and relative to subsequent recessions. Their analysis is based on cycle durations as defined by National Bureau of Economic Research (NBER) reference dates. However, much of macroeconomic analysis is based on (i) growth cycles (i.e., periods when the economy's production is above or below trend) rather than absolute increases or decreases in economic activity; and (ii) aggregate time series' volatility as the prime indicator of macroeconomic stability. In light of this, we reevaluate the March 1933 break point. First, using HP‐filtered quarterly gross national product (GNP), our analysis of growth cycle durations still implies a break point near 1933. Second, we test for structural breaks in the volatility of GNP growth rates and deviations from trends. These tests suggest a structural break considerably later than 1933, perhaps as late as the 1950s.     

Problems in the creation of an optimal currency zone in the Commonwealth of Independent States

The paper evaluates the features of the Commonwealth of Independent States as a regional economic union of states on the territory of the former Soviet Union. It examines the most noticeable conceptual approaches to the definition of strategy, the directions of CIS development, and the monetary and credit mechanisms of interactions among member states, as well as the feasibility of CIS transformation into an efficient economic union of states.     

Role of large companies in Russia’s oil and gas complex

The purpose of this article is to reconsider the interaction between major oil and gas companies and the state, which is especially important for modern Russia given its current conditions. General theoretical approaches are presented, as well as calculations of price and financial indicators reflecting the performance of these companies.
