Is there a quality bias in the Canadian CPI? Evidence from microdata

Rising consumer prices may reflect shifts by consumers to new higher‐priced products, mostly for durable and semi‐durable goods. I apply Bils’ (2009) methodology to newly available Canadian consumer price data for non‐shelter goods and services to estimate how price increases can be divided between quality growth and price inflation. I find that less than one third of observed price increases during model changeovers should be attributed to quality growth. This implies overall price inflation close to inflation measured by the official index. I conclude that, according to Bils’ methodology, the quality bias is not an important source of potential mismeasurement of CPI inflation in Canada.     

Talking Your Way into Entrepreneurial Support: An Analysis of Satisfaction Drivers in Entrepreneur Mutual Aid Groups

The role of organized peer networks in entrepreneurial support systems has been surprisingly neglected in the literature, despite their undisputed effectiveness in numerous areas outside the entrepreneurship realm. This study explores the efficacy of mutual aid groups for entrepreneurial support, as theoretically distinct from other group‐based mechanisms (such as peer group mentoring and many to one group mentoring). Drawing from respondent data of small, local mutual aid groups within the global entrepreneurship support organization (2,869 responses from members of 540 groups worldwide), we investigate the factors determining the entrepreneurs' satisfaction with the entrepreneur mutual aid groups. Understanding the antecedents of members' subjective satisfaction with the group serves an essential first step toward developing the models explaining the objective effectiveness of these organizations (e.g., performance, survival, and growth), in that the former is an essential, necessary condition for continuing participation in the voluntary mutual aid groups. Our analysis reveals that group climate and leadership are important drivers of group satisfaction.     

Optimal monetary policy under incomplete markets and aggregate uncertainty: A long-run perspective

This paper examines the role of monetary policy in an environment with aggregate risk and incomplete markets. In a two-period overlapping-generations model with aggregate uncertainty, optimal monetary policy attains the ex-ante Pareto optimal allocation. This policy aims to stabilize the savings rate in the economy by changing real returns of nominal bonds via variation in expected inflation. Optimal expected inflation is procylical and on average higher than without uncertainty. Simple inflation targeting rules closely approximate the optimal monetary policy.     

Expertise,university infrastructure and approaches to new venture creation: assessing students who start businesses

Abstract

Within the broader literature on contextual determinants of effectual and causal cognitive logics, the paper explores the drivers of causal and effectual reasoning in student-founders of new ventures, particularly focusing on the role of university entrepreneurship-related offerings and student prior business experience. Using the Global University Entrepreneurial Spirit Students’ Survey (GUESSS), the study involves a sample of 2179 student entrepreneurs from 26 countries. Our findings indicate that university entrepreneurship-related offerings such as curricular programming, co-curricular activities, and financial support play a differentiating role in the proclivity towards causal or effectual approaches across the groups of experienced and inexperienced student entrepreneurs. We also provide evidence that effectuation and causation are not mutually exclusive constructs: they are intertwined and can unfold simultaneously.     

Complementary Goods: Prices and Consumer Welfare Under Duopoly and Monopoly

We examine prices, profits, and consumer surplus for differentiated complementary goods under duopoly and a multi‐product monopoly. We find that little can be said about the relative magnitudes of prices of the components of a system of complementary goods under the alternative market structures. Although demand complementarity can lead to lower prices for either the primary or the secondary good under monopoly, both prices are not necessarily lower. The results unique to this paper are that, when two complementary goods form a system, the system price is unambiguously lower and consumer surplus and profits are higher under a multi‐product monopoly.     

The patterns and determinants of longevity in Russia's regions: Evidence from panel data

In this paper we examine whether regions of Russia have been converging or diverging in their longevity levels during the 1990s and evaluate the divergence effect of the 1998 financial crisis. We also estimate the impact of changes in poverty and public health spending on inter-temporal variations in longevity using regional-level panel data for 77 Russian regions from 1994 to 2000. Finally, we investigate the extent to which the gradual recovery in longevity observed after 1994 was derailed by the 1998 financial crisis and the public policy shifts required for regions to regain their Soviet-era levels of longevity. We find a significant negative effect of the 1998 crisis on longevity independently of the factors related directly to poverty and public health spending. In addition, a permanent negative shock to the incidence of poverty and the amount of publicly-provided health care in a region has enduring consequences on the population's health. Finally, the effect of increases in public health spending on longevity is related positively to the incidence of poverty. Journal of Comparative Economics 33 (4) (2005) 788–813.     

Inventories and real rigidities in New Keynesian business cycle models

Kryvtsov and Midrigan (2008) study the behavior of inventories in an economy with menu costs, fixed ordering costs and the possibility of stockouts. This paper extends their analysis to a richer setting that is capable of more closely accounting for the dynamics of the US business cycle. We find that the original conclusion survives in this setting: namely, the model requires an elasticity of real marginal cost to output approximately equal to the inverse intertemporal elasticity of substitution in consumption in order to account for the countercyclicality of the aggregate inventory-to-sales ratio in the data.
