The Impact of Socialism on Work Stoppages

The impact of socialism on work stoppages in 15 industrialized countries for the years 1956–1965 was tested using three measures of socialism: (1) the proportion of tangible wealth owned by the state, (2) the ratio of public welfare expenditures to gross national product, and (3) whether or not the socislist party was in power. Results of the analyses performed show that socialism a p peared to have little impact on work stoppage rates among the countries.     

LABOUR MOBILITY AND TRANS‐TASMAN CURRENCY UNION*

The prospect of a common currency for Australia and New Zealand has been canvassed by senior poli‐ticians and bureaucrats, and has been the subject of academic debate. According to Mundell (1961 ), a high degree of internal labour mobility is a desirable feature of currency unions. This study looks at the extent to which long‐term migration between Australia and New Zealand responds to output shocks. Estimated VAR models and panel Granger‐causality tests demonstrate that shocks to relative per capita output have a significant and symmetrical impact on migration flows between Australia and New Zealand, and most of the impact is felt after about one year. Separating the shocks to Australia and New Zealand shows that ‘pull’ effects are more important than ‘push’ effects. Additionally, the trajectory of the Australian economy proves particularly influential for the choice of New Zealand emigrants. Although permanent migration responds intuitively to the state of the economy in Australia and New Zealand, the level of these migration flows is low in comparison to Australian inter‐state migration; yet it is high in relation to any third country.     

MEASURING THE PRICE OF RESEARCH AND DEVELOPMENT OUTPUT

We construct a price index for the scientific R&D services industry, a significant producer of R&D in the United States. Unlike most previous R&D price indexes, our index is not based on input costs but rather on measures of R&D sales. Consequently, unlike input‐cost price indexes, our output‐based index is able to account for changes in productivity and markups in the scientific R&D services industry. We compute that scientific R&D services prices increased, on average, by 7.14 percent at an annual rate from 1987 to 2006. Using our index, we find that real revenues grew at an annual average rate of 2.85 percent. We then propose using our index, in combination with an input‐cost price index, to deflate total R&D nominal expenditures. We find that real total U.S. R&D expenditures grew at an average annual rate of 1.42 percent from 1987 to 2006.     

Dividend Changes and the Persistence of Past Earnings Changes

We examine whether the market interprets changes in dividends as a signal about the persistence of past earnings changes. Prior to observing this signal, investors may believe that past earnings changes are not necessarily indicative of future earnings levels. We empirically investigate whether a change in dividends alters investors' assessments about the valuation implications of past earnings. Results confirm the hypothesis that changes in dividends cause investors to revise their expectations about the persistence of past earnings changes. This effect varies predictably with the magnitude of the dividend change and the sign of the past earnings change.     

Estimating the New Keynesian Phillips Curve: A Vertical Production Chain Approach

It has become customary to estimate the New Keynesian Phillips Curve (NKPC) with generalized method of moments using a large instrument set that includes lags of variables that are ad hoc to the firm's price-decision problem. Researchers have also conventionally used real unit labor cost (RULC) as the proxy for real marginal cost even though it is difficult to support its significance. This paper introduces a new proxy for the real marginal cost term as well as a new instrument set, both of which are based on the micro foundations of the vertical chain of production. I find that the new proxy, based on input prices as opposed to wages, provides a more robust and significant fit to the model. Instruments that are based on the vertical chain of production appear to be both more valid and relevant toward the model.     

Financial Constraints, Competition, and Hedging in Industry Equilibrium

We analyze the hedging decisions of firms, within an equilibrium setting that allows us to examine how a firm's hedging choice depends on the hedging choices of its competitors. Within this equilibrium some firms hedge while others do not, even though all firms are ex ante identical. The fraction of firms that hedge depends on industry characteristics, such as the number of firms in the industry, the elasticity of demand, and the convexity of production costs. Consistent with prior empirical findings, the model predicts that there is more heterogeneity in the decision to hedge in the most competitive industries.     

The Impact of Central Bank Independence on Political Monetary Cycles in Advanced and Developing Nations

This paper examines the extent to which monetary policy is manipulated for political purposes during elections. We do not detect political monetary cycles in advanced countries or developing nations with independent central banks. We do find evidence, however, in developing countries that lack central bank independence. Furthermore, we find some evidence that these cycles are not caused by monetization of election-related fiscal expansions. This suggests that pressure by politicians on the central bank to exploit the Phillips curve may be an important factor in generating political monetary cycles.     

Sir William Petty,Ireland, and the making of a political economist, 1653–871

This paper offers a reassessment of the origins and derivation of many of Sir William Petty's economic ideas, based on an analysis of his unpublished papers. Petty's archive makes clear what a large part Ireland played in his writings, and it is suggested that this preoccupation is essential to an appreciation of him as an economist. It also demonstrates the point that Petty was not principally a theorist but rather a practical political economist whose schemes for the enrichment of the king's dominions were inspired by the underdevelopment which he experienced at first hand in Ireland.
