Using data on inter-dealer transactions, we find a 1 standard deviation increase in order flow (i.e. net pressure to obtain USD through FX swaps) increases the cost of dollar funding by up to 4 basis points after the 2008 crisis. This is explained by increased dispersion in dollar funding costs and quarter-end periods. We find central bank swap lines reduced the order flow to obtain USD through FX swaps, subsequently affecting the forward rate. In contrast, during quarter-ends and monetary announcements we observe high frequency adjustment of the forward rate.","PeriodicalId":381400,"journal":{"name":"Warwick Business School Finance Group Research Paper Series","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116033384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our measure is inversely related to the percentage of active predictors. Empirically, sparsity varies over time and displays an apparent countercyclical behavior. Proxies for financial conditions and for liquidity supply are key determinants of the variability in sparsity. Deteriorating financial conditions and illiquid times are associated with an increase in the number of characteristics that are useful to predict anomaly returns (i.e., the forecasting model becomes more dense). Looking at specific categories of characteristics, we find that variables classified as value, trading frictions and, in particular, profitability are robustly present throughout the sample. A strategy that exploits the dynamics of sparsity to time factors delivers substantial economic gain out-of-sample relative to both a random walk and a simple rolling window shrinkage estimator as well as standard models based on preselected, well-know characteristics like size, momentum, book-to-market, investment and accruals.","PeriodicalId":381400,"journal":{"name":"Warwick Business School Finance Group Research Paper Series","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122757828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Contrary to conventional wisdom, the optimal contract is not standard debt, and it is not monotonic. Instead, it resembles a contingent convertible (CoCo) bond. In particular: (i) if the profit manipulation and/or adverse selection are not severe, there exists a unique separating equilibrium in CoCos; (ii) in the intermediate region, if the distribution of earnings is unbounded above there exists a unique pooling equilibrium in CoCos, otherwise debt might be issued but it is never the unique equilibrium; (iii) finally, if profit manipulation is severe, there is no financing. These findings suggest that the standard monotonicity constraint exogenously imposed in the security design literature must be reconsidered. Crucially, profit manipulation is part of the optimal contract, and non-monotonic, convertible securities mitigate the asymmetric information problem. We discuss milestone payments in venture capital as an application.","PeriodicalId":381400,"journal":{"name":"Warwick Business School Finance Group Research Paper Series","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123015907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We demonstrate three implications of competition in speed. 1) We find more high frequency liquidity provision for lower price stocks with high market cap, where the one cent tick size has a higher constraint on price competition. 2) Speed has no impact on (the price) of liquidity, because speed competition already implies that liquidity providers cannot undercut each other’s price. We find that exogenous technology improvements improving speed at a one millisecond, microsecond or nanosecond level do not lead to improvements on quoted spread, effective spread, trading volume or variance ratio. However, the cancellation/execution ratio increases, short term volatility increases and market depth decreases. 3) It is relative speed that matters. We find evidence consistent with the quote stuffing hypothesis (Biais and Woolley, 2011) using NASDAQ channel assignment as identification. Competition in speed but not price leads to externalities based on the canonical definition of Laffont (2008). One possible policy solution is the deregulation of tick size or decrease the importance of time priority.","PeriodicalId":381400,"journal":{"name":"Warwick Business School Finance Group Research Paper Series","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125407153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to prior work, we focus on the firm level heterogeneity in the economic consequences, recognising that the level of uncertainty avoidance (UAI) in a country will influence the economic consequences derived from implementing the new standards. Country level uncertainty avoidance is predicted to lead to lower liquidity and Tobin’s Q, and a higher cost of equity for mandatory adopters in higher UAI countries, while higher UAI is expected to benefit voluntary adopters in terms of higher liquidity and Tobin’s Q, and a lower cost of equity. To test these predictions, we partition the firms into non-adopters, voluntary adopters, and mandatory adopters and also classify firms according to the change in their financial reporting quality. We analyse whether capital markets effects are different across the various groups based on the level of uncertainty avoidance in the host country. We find that prior to the mandatory adoption of IFRS by the EU member states, voluntary adopters in higher UAI countries benefited from increased liquidity and Tobin’s Q, compared to identical firms in lower UAI countries, mandatory adopters and non-adopters. However, we find that this result is not persistent post the EU mandate, and that UAI influences both mandatory and voluntary adopters in a similar manner post 2005. The results from the cost of equity analysis suggest that market participants treat mandatory and voluntary adopters in an almost identical manner and that a higher UAI leads to both groups of firms exhibiting a reduction in their cost of equity. Our findings imply that uncertainty avoidance is able to explain part of the heterogeneity exhibited in the capital market outcomes between firms and across countries that have adopted IFRS.","PeriodicalId":381400,"journal":{"name":"Warwick Business School Finance Group Research Paper Series","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122936958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper investigates the feasibility of the Beatlestrap, an optimization-free approach to bootstrap. It is shown that, ex-post, M-estimators may be expressed in terms of simple arithmetic averages therefore reducing the bootstrap of Wald statistics to the bootstrap of averages. Similarly, it is shown how the Lagrange Multiplier and the Likelihood Ratio statistics may be bootstrapped bypassing the objective function's multiple optimizations. The proposed approach is extended to simulation based Indirect Estimators.
