DETERMINANTS OF INFLATION IN GHANA: AN EMPIRICAL INVESTIGATION

This paper provides an empirical analysis of the factors accounting for inflation dynamics in Ghana using the bounds test and other econometric approaches. We find that real output, nominal exchange rate, broad money supply, nominal interest rate and fiscal deficit play a dominant role in the inflationary process in Ghana. To the extent that output growth by far has the strongest impact on inflation, targeting supply‐side constraints will help moderate price inflation. The paper concludes that inflation in Ghana is explained by a combination of structural and monetary factors consistent with prior studies.

A Sports Consumption Comparative Study on Urban Residents between Chongqing and Some Cities in Advanced Eastern and Western Regions

This paper compares and analyzes the EE consumption structure of urban residents in Chongqing and other cities in Eastern and Western areas （Such as Beijing, Shanghai, Shenzhen, Zhejiang, Chengdu, Xi＇an, Guizhou）. The research shows the level of P.E consumption is in the lower-middle position, and its structure is not reasonable. This paper also explores the factors that restrict P.E consumption of urban residents in Chongqing city and puts up some feasible suggestions on improving P.E consumption structure and increasing P.E consumption level.     

The fertility of the Irish in the United States in 1910

The relatively high marital fertility of the Irish in the United States in the 19th century has long been interpreted as evidence for the persistence of a distinctive Irish culture in the United States. This claim echoes a similar view of Irish-American marriage patterns. Recent work has shown that the marriage patterns of the Irish in the United States were similar to native-born whites with similar occupational and other characteristics. This paper studies the reasons for the high fertility of Irish-Americans in 1910. Irish-born women in that year had much larger families than the typical native-born woman, and little of the difference can be attributed to other characteristics. Second-generation Irishwomen were less distinctive in this regard, although even they differed from the natives primarily because of a different proclivity to have a large family. Our results signal the complexity of immigrant adjustment to a new environment; the Irish largely abandoned one aspect of Irish demographic behavior while clinging to another.
