Effects of Shoe-Leather Cost on Consumer Cash Withdrawal Behavior

Heng Chen, Matthew Strathearn, Marcel Voia

Abstract This paper studies an empirical model of shoe-leather cost applied to consumer cash withdrawal. The unique feature is to estimate the effect of shoe-leather cost from the cash inventory model by filtering out free-type consumers who do not incur shoe-leather costs. When compared to the costly-type consumers, the free-type do not need to go out of their ways from home to visit banks to withdraw cash because they can economise their travel costs by combining withdrawals with other activities, such as, one-stop multi-purpose trip on either their ways to work or shopping. We find that the cash withdrawal frequency significantly decreases with the travel distance; otherwise the estimated shoe-leather cost without distinguishing between free- and costly-types is close to zero and insignificant. This finding suggests that in order to maintain cash accessibility, the policy need not only consider the supply of physical branch infrastructure, but also account for consumer’s travel pattern.

Explaining bitcoin ownership in Canada: Trends from 2016 to 2021

Daniela Balutel, Walter Engert, Christopher Henry, Kim Huynh, Marcel Voia

Abstract This paper studies the dynamics of bitcoin ownership from 2016 to 2021, using the Bank of Canada's Bitcoin Omnibus Surveys. The estimated rate of bitcoin ownership jumped to 13% in 2021, up from the 5% observed in the previous three years. On one hand, this increase reflected broader economic trends related to increased savings and investment of Canadians during the COVID‐19 pandemic, along with financial technology companies providing accessible and user‐friendly platforms for buying bitcoin. Looking deeper, we use econometric models to quantify several specific ways in which bitcoin became more mainstream as an investment in 2021. Finally, we investigate the high cash holdings of bitcoin owners across time.

Surviving the Storm: Hazard Models and Signaling Shocks in Bitcoin Prices

Daniela Balutel, Marcel Voia

This paper explores factors influencing Bitcoin price fluctuations and identifies key indicators for predicting market movements. Positive price trends are associated with increased network activity, larger block sizes, and higher returns on investment, providing potential opportunities for investors. Conversely, increased values in Address Action Count, Capital Market Value, Coinbase Issuance, and Return on Investment suggest a higher risk of negative price shocks and potential downward market trends. The study also highlights mitigating factors like Bitcoin capitalization, current supply, and current velocity, offering valuable insights for enhancing market stability. Furthermore, the findings suggest that as the absolute magnitude of price shocks increases, the occurrence of negative price shocks surpasses that of positive ones. Simultaneously, there is a significant decrease in the predictability of negative shocks relative to the predictability of positive price shocks.

Does more finance lead to longer crises?

Clément Mathonnat, Alexandru Minea, Marcel Voia

Empirical studies emphasise that higher financial development (FD) amplifies the output cost of banking crises. However, no study has so far investigated the effect of FD on another key dimension of banking crises, namely their duration. Using a large sample of banking crises over the 1977-2014 period, we find that higher FD is associated with a significant increase in the duration of banking crises (DBC). This result is robust to a broad range of alternative specifications and is unaffected by unobserved heterogeneity or endogeneity. Finally, we show that the effect of FD on DBC is subject to nonlinearities and varies across decades and with the level of economic development.

Bootstrap bias correction for average treatment effects with inverse propensity weights

Gubhinder Kundhi, Marcel Voia

The estimated average treatment effect in observational studies is biased if the assumptions of ignorability and overlap are not satisfied. To deal with this potential problem when propensity score weights are used in the estimation of the treatment effects, in this paper we propose a bootstrap bias correction estimator for the average treatment effect (ATE) obtained with the inverse propensity score (BBC-IPS) estimator. We show in simulations that the BBC-IPC performs well when we have misspecifications of the propensity score (PS) due to: omitted variables (ignorability property may not be satisfied), overlap (imbalances in distribution between treatment and control groups) and confounding effects between observables and unobservables (endogeneity). Further refinements in bias reductions of the ATE estimates in smaller samples are attained by iterating the BBC-IPS estimator.

Estimation of Health Care Demand and its Implication on Income Effects of Individuals

Hossein Kavand, Marcel Voia

Abstract Zero inflation and over-dispersion issues can significantly affect the predicted probabilities as well as lead to unreliable estimations in count data models. This paper investigates whether considering this issue for German Socioeconomic Panel (1984–1995), used by Riphahn et al. (2003), provides any evidence of misspecification in their estimated models for adverse selection and moral hazard effects in health demand market. The paper has the following contributions: first, it shows that estimated parameters for adverse selection and moral hazard effects are sensitive to the model choice; second, the random effects panel data as well as standard pooled data models do not provide reliable estimates for health care demand (doctor visits); third, it shows that by appropriately accounting for zero inflation and over-dispersion there is no evidence of adverse selection behaviour and that moral hazard plays a positive and significant role for visiting more doctors. These results are robust for both males and females’ subsamples as well as for the full data sample
