Recent developments of the autoregressive distributed lag modelling framework

We review the literature on the autoregressive distributed lag (ARDL) model, from its origins in the analysis of autocorrelated trend stationary processes to its subsequent applications in the analysis of cointegrated non-stationary time series. We then survey several recent extensions of the ARDL model, including asymmetric and non-linear generalisations of the ARDL model, the quantile ARDL model, the pooled mean group dynamic panel data model and the spatio-temporal ARDL model.     

Health insurance coverage during the COVID-19 pandemic: The role of Medicaid expansion

Using data from the US Census Bureau's Household Pulse Survey, we analyzed the likelihood of loss of health insurance and enrollment into new health coverage during the early months of the COVID-19 pandemic. Loss of employment was associated with a significant increase in the likelihood of loss of health insurance and, specifically, an increase in the likelihood of employer-sponsored health insurance. However, individuals in Medicaid expansion states experienced a lower likelihood of loss of health insurance compared with individuals in nonexpansion states. At the same time, there was a statistically significant increase in Medicaid enrollment in expansion states, by 3.2 percentage points. Reemployment or acquiring employment was associated with a gain in health insurance coverage. During an economic downturn, eligibility, and coverage gaps leave many without affordable coverage options, and the pandemic will likely bring renewed attention to gaps in Medicaid coverage in nonexpansion states.     

Financial development and the effect of cross-border bank flows on house prices

We analyze the role of financial development as a buffer to diminish the effect of cross-border bank flows shocks on house prices across 38 countries. In less financially developed countries, the observed response is markedly positive. As development increases, the response is tempered and becomes less important. Cross-border bank flows shocks are important in explaining the historical dynamics of house prices in financially less developed countries, while monetary policy shocks are key in the most financially developed markets. Heterogeneity in responses within each level of financial development is associated with levels of maximum loan-to-value ratios and a ratio of cross-border bank inflows over total liabilities abroad.     

It is different than what I saw online: Negative effects of webrooming on purchase intentions

Webrooming is a two-stage shopping process that begins with examining product options online followed by making a purchase at an offline store. In four experiments, we investigate webrooming effects on product evaluation and purchase intentions. The results suggest that webrooming (vs. non-webrooming) has negative impacts on (1) perceived product performance vis-à-vis expectations and (2) purchase intentions for the products offline. Our moderated-mediation analyses show that webrooming leads to lower perceived product performance, which in turn results in lower purchase intentions, and participants’ Need for Touch (NFT) moderates the negative mediation effect, which is stronger with instrumental NFT than autotelic NFT. However, this moderated-mediation effect is attenuated when products are searched across multiple categories. These findings contribute to the marketing literature by providing a more nuanced understanding of how two-stage, webrooming behavior affects consumers’ cognitions and purchase decisions. They also provide several managerial implications that when controlling for time intervals between the stages, (1) webrooming may adversely affect retailers’ business outcomes when webrooming within a single (e.g., blankets), related (e.g., baby products), and unrelated product categories; (2) thus, creating an integrated online-to-offline cross-channel customer experiences is critical to minimize the negative webrooming effects on final sales.     

Brand royalty flows within large business groups: The effect of holding company structure and related party transactions committees

This study investigates the intragroup flows of brand royalties within large Korean business groups, known as chaebols. We find that member firms pay a greater amount of brand royalties when the business groups they are part of adopt a holding company governance structure, consistent with the bitter denunciation that chaebols transfer wealth from member firms to holding companies over which they have direct control. However, member firms pay a smaller amount of brand royalties when their related-party transactions (RPTs) are monitored by a designated RPT committee on the board of directors. The results show that monitoring RPTs is effective in mitigating the alleged unethical wealth transfer through excessive brand royalties within large business groups. Our study adds to the literature on RPTs by shedding new light on brand royalty, specifically by illustrating how intragroup brand royalties are determined and charged to member firms, and by introducing the RPT committees as a new internal governance mechanism to discourage abusive RPTs.     

Less timely earnings announcements and voluntary disclosure

The release of earnings information has become less timely in recent years partly because firms increasingly disclose earnings concurrently with their periodic reports (e.g., 10-Ks, 10-Qs). We examine whether firms use voluntary disclosure to mitigate the negative economic consequences of less timely earnings announcements (EAs). We find that firms with less timely EAs are more likely to provide voluntary 8-K filings over the period leading to the EA. We also find that investors’ demand for timely information, the nature of earnings news and litigation risk affect the extent to which firms provide voluntary disclosure to compensate for less timely EAs. The negative effect of less timely EAs on information asymmetry is attenuated when firms provide voluntary 8-K filings prior to EAs. Overall, our findings suggest that firms voluntarily communicate with investors using voluntary disclosure when their EAs are less timely.
