Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate.The paper shows how excessive reporting, called "crying wolf", can dilute the information value of reports. Excessive reporting is investigated by undertaking the first formal analysis of money laundering enforcement. Banks monitor transactions and report suspicious activity to government agencies, which use these reports to identify investigation targets. Banks face fines should they fail to report money laundering. However, excessive fines force banks to report transactions which are less suspicious. The empirical evidence is shown to be consistent with the model's predictions. The model is used to suggest implementable corrective policy measures, such as decreasing fines and introducing reporting fees.

Working Papers describe research in progress by the author(s) and are published to elicit comments and to further debate.The paper shows how tax rate cuts can increase revenues by improving tax compliance. The intuition is that tax evasion has externalities: tax evaders protect each other, because they tie down limited enforcement capacity. Thus, relatively small tax rate cuts, which decrease incentives to evade taxes, can lead to increased revenues through spillovers -creating Laffer effects. Interestingly, tax rate cuts here imply increasing effective taxes. The model is consistent with what happened in Russia, and may provide basis for further thinking about tax rate cuts in other countries.

We combine a rarely accessed BIS database on bilateral cross-border lending flows with crosscountry data on macroprudential regulations. We study the interaction between the monetary policy of major international currency issuers (USD, EUR and JPY) and macroprudential policies enacted in source (home) lending banking systems. We find significant interactions. Tighter macroprudential policy in a home country mitigates the impact on lending of monetary policy of a currency issuer. For instance, macroprudential tightening in the UK mitigates the negative impact of US monetary tightening on USD-denominated cross-border bank lending outflows from UK banks. Vice-versa, easier macroprudential policy amplifies impacts. The results are economically significant.

We show that currency networks in cross-border bank lending have a significant impact on the size, distribution, and direction of international monetary policy spillovers. Utilizing a novel dataset, we map the major currency networks in international banking and show that the US dollar dominates at the global level. Next, we provide evidence that during the 2013 Fed taper tantrum, the degree of exposure to US dollar lending had a significant impact on cross-border bank lending growth. Most notably, it had a strong negative impact on cross-border flows to emerging markets.

We study the effect of macroprudential measures on cross-border lending during the taper tantrum, which saw a strong slowdown of cross-border bank lending to some jurisdictions. We use a novel dataset combining the BIS Stage 1 enhanced banking statistics on bilateral cross-border lending flows with the IBRN’s macroprudential database. Our results suggest that macroprudential measures implemented in borrowers’ host countries prior to the taper tantrum significantly reduced the negative effect of the tantrum on cross-border lending growth. The shock-mitigating effect of host country macroprudential rules are present both in lending to banks and non-banks, and are strongest for lending flows to borrowers in advanced economies and to the non-bank sector in general. Source (lending) banking system measures do not affect bilateral lending flows, nor do they enhance the effect of host country macroprudential measures. Our results imply that policymakers may consider applying macroprudential tools to mitigate international shock transmission through cross-border bank lending.
