Essays on Inflation and Output: A Search-Theoretic Approach

Liu, Qian 19 July 2010 (has links)
This dissertation examines the welfare effects of inflation on employment and output in three different market settings. The theoretical frameworks build on recent studies in the monetary search literature that explicitly models the microfoundations of money and study how monetary policy interacts with real variables. The first essay studies the relationship between inflation and unemployment in a general equilibrium framework where inflation has differential effects on employed and unemployed workers. The model finds that inflation can either increase or decrease employment and output, depending on goods and labor market institutions. Sales taxes, the degree of competitiveness in the goods market and imperfect indexation of unemployment insurance benefits are the major factors determining the direction of this relationship. Through a comparison of these parameters, the model predicts an inflation-unemployment relation that is qualitatively consistent with the empirical evidences. The second essay, co-authored with Liang Wang and Randall Wright, investigates the effect of inflation on people's trading behavior in the goods market. By focusing on buyers' search intensity on the extensive margin, the model unambiguously predicts a rise in inflation leads to an increase in the speed with which agents spend their money and velocity. This is consistent with the phenomenon described by the conventional "hot potato" effect of inflation. We also discuss the welfare implications of different monetary policy. In some circumstances inflating above the Friedman rule may be optimal, but the effect of inflation on output is always negative. The third essay, co-authored with Allen Head, Guido Menzio and Randall Wright, examines the effect of monetary growth on output in a general equilibrium model where price stickiness arises as an equilibrium outcome. The model makes several predictions about individual firms' price adjustment behavior that are consistent with micro data. For instance, the frequency (duration) of price changes increases (decreases) with inflation and the price change hazard declines over time. In contrast to the New Keynesian literature, price rigidities in our model does not generate monetary non-neutrality. Higher inflation reduces real output in the long run, but changes in the aggregate price level has no effect on real allocations. / Thesis (Ph.D, Economics) -- Queen's University, 2010-07-17 00:52:41.487

Differentials in unemployment duration across households in South Africa: A two-level modelling approach

Lartey, Nathaniel January 2018 (has links)
Philosophiae Doctor - PhD / This study aimed to examine the structural changes affecting the duration of unemployment across households in South Africa. It made use of existing datasets from the Labour Force Survey produced by Statistics South Africa, covering a period of six years (2011-2016). Relations among demographic and household variables were explored to determine how they related to unemployment duration. On the basis of the relations identified, a predictive analysis of unemployment duration was attempted using two-level modelling. The results suggest a significant difference in the duration of unemployment, according to the individual socio-demographic characteristics and the household moderating variables. More specifically, the greatest share percentage of both men and women experiencing long-term unemployment were found within the age group 25-34 years. The study also found that the percentage share of Non-White population groups experiencing longer duration of unemployment was more than for the White population group. Another variable found to have great influence on the duration of unemployment was the individual’s previous work experience. Going beyond the individual’s socio-demographic characteristics to consider household variables. It was found that unemployed workers living in households headed by a female are more vulnerable to longer unemployment duration. The study found individuals living in smaller households displaying longer unemployment duration. Also, it was found that individuals living in less endowed households (households where no one or few people were in gainful employment) were more vulnerable to experiencing longer unemployment spells. The study concluded with some recommendations for employment policy and follow-up research.
