In this presentation I view a Malmquist productivity index as a theoretical index with desirable properties. I then discuss the properties of three approximations to it: an empirical Malmquist index, and Fisher and Tornqvist indexes. Next I discuss the decomposition properties of the theoretical...

We define a segregation ordering as a ranking of cities from most segregated to least segregated. \ We propose a set of basic properties that any reasonable segregation ordering should have. \ We then fully characterize the class of segregation orderings that satisfy these basic properties. \ We...

The economies of the former Soviet Bloc experienced large declines in output during the decade of transition which began with the collapse of the Soviet Union in 1991. Yet there are many reasons to believe that measured output and official deflators provide a poor proxy for the change in real...

In applied econometric literature, the causal inferences are often made based on highly temporally aggregated or systematically sampled data. A number of theoretical studies have pointed out that temporal aggregation has distorting effects on causal inference and systematic sampling preserves...

This paper examines the performance of the U.S.~commercial banking industry over 1984--2002. Rather than measuring performance relative to the unknown (and difficult-to-estimate) boundary of the production set, performance for a given bank is measured relative to {\it expected} maximum output...

The Stock--Watson coincident index and its subsequent extensions assume a static linear one-factor model for the component indicators. Such assumption is restrictive in practice, however, with as few as four indicators. In fact, such assumption is unnecessary if one poses the index construction...

This paper develops a monopolistic competition model to study the characteristics of products, such as quality improvement and product diversity (function-specialization and individualization), and the division of labor in production. Different from the ordinary economic model, our utility...

Empirical evidences tell us that in the recent years the expansion period is increased with reduction of the contraction period in the U.S. business cycles. Moreover, the business cycles in the United States also show the trend to be moderated with recent economic growth induced and supported by...

Certain problems in comparative statics, including (but not exclusively) certain problems in consumer theory, cannot be easily addressed by the methods of lattice programming. One reason for this is that there is no order on the choice space which orders choices in a way which conforms with the...

The well-behaved (downward sloping and consistent to the consumer surplus) Marshallian demand function forms a basis of the partial equilibrium analysis both in positive and normative perspectives, since the downward slopness and some other regularity conditions imply that there exists a...
