Income Convergence across U.S. States: An Analysis Using Measures of Concordance and Discordance*

Abstract. This paper presents methods to analyze convergence in cross‐sectional data collected over time using distribution free statistics that are not sensitive to the magnitudes involved. Measures of concordance and discordance are employed in the empirical analysis of real personal income per capita for 48 U.S. States over the period 1929–2002. Although most States are converging with each other, some are converging faster than others. The methods used have the flexibility to focus on specific characteristics such as convergence in absolute differences or convergence in the ratio of rewards. The methods may also be used to consider convergence without switching and additionally be applied to other features such as the percentiles of the distributions.     

Regional Exchange Rate Indexes for the United States

In this paper we construct exchange rate indexes for the nine U.S. Bureau of the Census regions. The results indicate there are nontrivial differences between them and an identically created overall U.S. exchange rate index. The national index is cointegrated with only two of these regional indexes, and in a Granger sense, it is causing one regional index. In addition, our results indicate that two of the regional exchange rate indexes are interchangeable with the national index. These results show that researchers investigating how exchange rate changes affect regional exports or regional economic growth should be cautious in making inferences based upon a national exchange rate index.

Abstract

The departure point of this article is the postmodern critique of my book, The Dead Will Arise. The object of the article is not however to defend either the book itself or the 'constructionist’ school of historiography to which it apparently belongs. The first part of the article seeks to clarify the epistemological basis on which constructionist historians claim the right to engage with and interpret the past. In the process of doing so, it establishes a conceptual framework capable of defining relevance in the context of post-democratic South African historiography. It argues that historians have a duty to prioritise the ‘scars’ and ‘pitfalls’ of South African history failing which they become mere lapdogs, decorative but irrelevant. It is further argued that, although historians have the right to study whatever they choose, there is something intrinsically wrong with institutional mechanisms which produce nothing but lapdogs, and that university history departments need to take more of a lead.
