Econometric policy evaluation: A critique

The goal of this piece is to survey the developing and rapidly growing literature on the economic consequences of COVID-19 and the governmental responses, and to synthetize the insights emerging from a very large number of studies. This survey: (i) provides an overview of the data sets and the techniques employed to measure social distancing and COVID-19 cases and deaths; (ii) reviews the literature on the determinants of compliance with and the effectiveness of social distancing; (iii) mentions the macroeconomic and financial impacts including the modelling of plausible mechanisms; (iv) summarizes the literature on the socioeconomic consequences of COVID-19, focusing on those aspects related to labor, health, gender, discrimination, and the environment; and (v) summarizes the literature on public policy responses.

Purpose




This paper aims to examine the antecedents of customer inertia (i.e. knowledge, confusion, perceptions of competitor similarity and switching costs) and their relationship to customer satisfaction, service providers’ switching intentions and actual switching behavior. Customer inertia is said to reduce the incidence of service provider switching; however, little is known about the antecedent drivers of inertia.




Design/methodology/approach




The conceptual model was tested by a longitudinal/discontinuous panel design using an online survey research of 1055 adult (i.e. +18 years old) subscribers to cell phone services. Partial least squares (PLS) path modeling was used to simultaneously estimate both the measurement and structural components of the model to determine the nature of the relationships between the variables.




Findings




Findings of the PLS structural model provide support for the direct relationship between customer inertia and its antecedents (i.e. knowledge, confusion, perceptions of competitor similarity and switching costs). The results show that customer inertia has a moderate negative effect on the intention to change service providers but had no measurable effect on the actual behavior of changing service providers, other than indirectly, by influencing the perception of difficulty in switching some 11 months later. Further results from an analysis of indirect pathways of the antecedents to inertia show that switching costs are the only variable which indirectly reduce intentions to change service providers. The results also show that the effect of satisfaction on switching service providers is partially moderated by inertia. Importantly, these relationships are reasonably robust given past switching behavior and contract status of consumers.




Research limitations/implications




The authors find evidence which explains some of the causes of inertia, and show that it has both direct and moderating effects on service provider switching intentions, though not necessarily the behavior of changing service providers. However, support was found for its indirect role through intent as an influence on switching behavior. Importantly, the authors find that inertia has lingering effects, in that it influences the perception of switching difficulties and, hence, behavior up to 11 months in the future.




Practical implications




Managerial implications are that service firms can profit from customer inertia through a reduction in churn. However, high levels of customer inertia over the longer term may increase the level of customer vulnerability to competitor offers and marketing activities, as satisfaction with the provider does not in itself explain switching intentions or behavior.




Originality/value




This study is the first study to contribute to an understanding of the antecedent drivers of customer inertia with respect to service provider switching and to empirically evaluate a variety of antecedent factors that potentially affect switching intentions. Importantly, the long lasting latent effect of inertia in indirectly influencing service switching behavior was found to persist some 11 months later.

Inertia in services: causes and consequences for switching

This paper examines the variability of workers’ earnings in Canada over the period 1982–2006. We decompose the total variance of workers’ earnings into a ‘permanent’ component between workers and a ‘transitory’ earnings instability component over time for given workers. We then investigate the statistical relationships between these components and indicators for the business cycle. The most marked change in earnings variances in Canada since 1982 is the general rise in total earnings variance, which is essentially driven by a quite dramatic rise in long-run earnings inequality. The patterns across age categories of the two variance components are almost opposite. Long-run earnings inequality generally rises with age, but earnings instability is seen to generally decline with age, so that earnings instability is markedly highest among entry age workers. Unemployment rate effects are positive on almost all variance measures, while higher unemployment is associated with widened long-run earnings differentials and greater short-run earnings instability.
