This study proposes a novel instrumental variable construction procedure based on international trade concentration that has a sufficiently strong first stage for exchange rate policy choice globally and applies it to revisit the causal effects of exchange rate regimes on macroeconomic outcomes....

Financial markets are useful indicators of public beliefs and dispersed knowledge on future outcomes and policy efficiency, especially in periods of uncertainty. 51 national stock markets successfully absorb publicly available information regarding COVID-19 and anticipate policy measures being...

This paper is the first to rigorously test commonly cited simplistic theories of cryptocurrency pricing, namely, cost-based model and Metcalfe's law, using causal inferences from the instrumental variables approach on block-level data for six proof-of-work coins. Positive effects of hashrate and...

This paper uses a unique dataset of 120 regulatory events from five classes to test the relevance of the regulatory framework for cryptocurrency value. Time-series market-wide estimates and panel estimates for 300 individual coins and tokens show statistically and economically significant impact...

This study applies Benford’s law to detect anomalies in county-level vote data for the 2020 US presidential election. Most prominent distribution violations are observed with Republican vote counts in blue states, all vote counts in states won by the Democratic candidate, and Democratic vote...

This study develops a novel generalised seasonality test that utilises sequential dummy variable regressions for seasonality periodicity equal to prime numbers. It allows both to test for existence of any seasonal patterns against the broad null hypothesis of no seasonality and to isolate most...

This paper provides an empirical analysis of FTSE100 stock returns during the period of 2009 to 2013 with an aim to assess the relevancy of Fama-French three factor model post financial crisis of 2008. FTSE100 index was chosen in particular as it is benchmark of the prosperity among UK stocks....

In this paper, an original international trade mathematical model is suggested. It studies a possibility of equilibrium on a world market of n countries and m tradable goods, applying linear algebra, linear programming and cooperative game theory (precisely, Shapley value). The model shows that...

In this article we develop a fairly simple mathematical model of a competitive consumer loan market. Given the market deposit rate and the structure of the public's time preference it predicts the equilibrium interest rate on consumer loans and the equilibrium degree of collateral coverage (the...
