Reserve Bank of New Zealand Discussion Papers by Daan SteenkampHow bubbly is the New Zealand dollar?2017-04-26T06:23:00ZThis paper tests for the existence of bubbles in the value of the New Zealand dollar. A common definition of an asset price bubble is the existence of explosive dynamics. This paper tests for periods of explosiveness in the New Zealand dollar measured at a monthly and quarterly frequency. To determine whether, during any explosive changes, the exchange rate was disconnected from changes in relative economic fundamentals, these tests are also applied to three models of exchange rate determination. This paper finds no evidence of episodes when either the New Zealand dollar or its fundamentals were explosive.How bubbly is the New Zealand dollar?Abstracthttp://www.rbnz.govt.nz/research-and-publications/discussion-papers/2017/dp2017-03Full texthttp://www.rbnz.govt.nz/-/media/ReserveBank/Files/Publications/Discussion%20papers/2017/dp17-03.pdfDaan SteenkampDaan Steenkamp2017-04-26Reserve Bank of New Zealand Discussion PapersC15C32F31Explosiveness in G11 currencies

Reserve Bank of New Zealand Discussion Papers by Daan SteenkampExplosiveness in G11 currencies2017-04-26T06:23:00ZThis paper tests for explosiveness in G11 currencies in daily data using a methodology that accounts for the possibility of non-stationary volatility. The results suggest that bouts of explosiveness in exchange rates are uncommon at a daily frequency. However, periods of explosiveness tend to last for several days. Such episodes only involve small changes in actual currency levels, which usually reverse shortly after. This paper identifies the currency in a currency pair that is experiencing explosive dynamics by also considering the dynamics of effective exchange rates of different currencies. There is high concordance with explosiveness in the broad value of the US dollar exchange rate, suggesting that there are relatively few instances where explosiveness in individual cross-rates reflected country-specific factors.Explosiveness in G11 currenciesAbstracthttp://www.rbnz.govt.nz/research-and-publications/discussion-papers/2017/dp2017-02Full texthttp://www.rbnz.govt.nz/-/media/ReserveBank/Files/Publications/Discussion%20papers/2017/dp17-02.pdfDaan SteenkampDaan Steenkamp2017-04-26Reserve Bank of New Zealand Discussion PapersC12C15C22F31Financial frictions and the real economy

National Bank of Poland Working papers by Siem Koopman, André Lucas and Marcin ZamojskiDynamic term structure models with score-driven time-varying parameters: estimation and forecasting2017-01-01T00:00:00ZWe consider score-driven time-varying parameters in dynamic yield curve models and investigate their in-sample and out-of-sample performance for two data sets. In a univariate setting, score-driven models were shown to offer competitive performance to parameter-driven models in terms of in-sample fit and quality of out-of-sample forecasts but at a lower computational cost. We investigate whether this performance and the related advantages extend to more general and higher-dimensional models. Based on an extensive Monte Carlo study, we show that in multivariate settings the advantages of score-driven models can even be more pronounced than in the univariate setting. We also show how the score-driven approach can be implemented in dynamic yield curve models and extend them to allow for the fat-tailed distributions of the disturbances and the time-variation of variances (heteroskedasticity) and covariances.Dynamic term structure models with score-driven time-varying parameters: estimation and forecastingFull texthttp://www.nbp.pl/publikacje/materialy_i_studia/258_en.pdfAndré LucasSiem KoopmanMarcin ZamojskiSiem Koopman, André Lucas and Marcin Zamojski2017National Bank of Poland Working papersC15C32C33C58C63E43E52E58Evaluation of Exchange Rate Point and Density Forecasts: an application to Brazil

Central Bank of Brazil Working Papers by Wagner Piazza Gaglianone and Jaqueline Terra Moura MarinsEvaluation of Exchange Rate Point and Density Forecasts: an application to Brazil2016-11-29T06:23:00ZIn this paper, we construct multi-step-ahead point and density forecasts of the exchange rate, from statistical or economic-driven approaches, using financial or macroeconomic data and using parametric or nonparametric distributions. We employ a set of statistical tools, from different strands of the literature, to identify which models work in practice, in terms of forecast accuracy across different data frequencies and forecasting horizons. We propose a novel full-density/local analysis approach to collect the many test results, and deploy a simple risk based decision rule to rank models. An empirical exercise with Brazilian daily and monthly data reveals that macro fundamentals matter when modeling the risk of exchange rate appreciation, whereas models using survey information or financial data are the best way to account for the depreciation risk. These findings have relevance for econometricians, risk managers or policymakers interested in evaluating the accuracy of competing exchange rate models.Evaluation of Exchange Rate Point and Density Forecasts: an application to BrazilAbstracthttp://www.bcb.gov.br/pec/wps/port/wp446.asp?idiom=IFull texthttp://www.bcb.gov.br/pec/wps/ingl/wps446.pdfWagner P.

Board of Governors of the Federal Reserve System FEDS series by Edward Herbst and Frank SchorfheideTempered Particle Filtering2016-09-07T17:38:00ZThe accuracy of particle filters for nonlinear state-space models crucially depends on the proposal distribution that mutates time t-1 particle values into time t values. In the widely-used bootstrap particle filter this distribution is generated by the state-transition equation. While straightforward to implement, the practical performance is often poor. We develop a self-tuning particle filter in which the proposal distribution is constructed adaptively through a sequence of Monte Carlo steps. Intuitively, we start from a measurement error distribution with an inflated variance, and then gradually reduce the variance to its nominal level in a sequence of steps that we call tempering. We show that the filter generates an unbiased and consistent approximation of the likelihood function. Holding the run time fixed, our filter is substantially more accurate in two DSGE model applications than the bootstrap particle filter.Tempered Particle FilteringFull texthttp://www.federalreserve.gov/econresdata/feds/2016/files/2016072pap.pdfEdward HerbstFrank SchorfheideEdward Herbst and Frank Schorfheide2016-09Board of Governors of the Federal Reserve System FEDS seriesC11C15E10The Rewards of Self-Discovery: Learning and Firm Exporter Dynamics

The option value generated by the acquisition of more information is key to understanding firm dynamics as the discovery stage lasts as long as this option value is positive. I use the model to study the impact of export promotion policies that temporarily subsidize the fixed costs of exporting. These policies can result in long-lived increases in aggregate trade, but their effectiveness crucially depends on the speed of learning.The Rewards of Self-Discovery: Learning and Firm Exporter DynamicsFull texthttp://www.banxico.org.mx/publicaciones-y-discursos/publicaciones/documentos-de-investigacion/banxico/{240D1C65-416C-F996-5D60-8C28924B1DF8}.pdfAlfonso Cebreros Zurita CarlosCebreros Zurita Carlos Alfonso2016-06Bank of Mexico Working PapersC15D21D22D83F12F14L11L25Covariate-augmented unit root tests with mixed-frequency data

This paper tries to tackle this issue by assessing whether it is possible to improve the power performance of covariate-augmented unit root tests, namely the ADF family of tests, by exploiting mixed-frequency data. We use the mixed data sampling (MIDAS) approach to deal with mixed-frequency data.

Netherlands Bank DNB Working Papers by Jon Danielsson and Chen ZhouWhy risk is so hard to measure2016-01-06T06:17:59ZThis paper analyses the accuracy and reliability of standard techniques for risk analysis used by the financial industry as well as in regulations. We focus on the difference between valueatrisk and expected shortfall, the small sample properties of these risk measures and the impact of using an overlapping approach to construct data for longer holding periods. Overall, we find that risk forecasts are extremely uncertain at low sample sizes. By comparing the estimation uncertainty, we find that valueatrisk is superior to expected shortfall and the time-scaling approach for risk forecasts with longer holding periods is preferable to using overlapping data.

Bank of Italy Working Papers by Pier Luigi Conti, Daniela Marella and Andrea NeriStatistical matching and uncertainty analysis in combining household income and expenditure data2015-07-15T12:37:00ZThe availability of microdata on both income and expenditure is highly recommended if one wants to assess the distributional consequences of policy changes. In Italy, the main sources used for estimating household income and expenditure are the Bank of Italy's Survey on Household Income and Wealth and the Italian National Institute of Statistics Household Budget Survey.
However, there is no single data source containing information on both expenditure and income. The problem is generally overcome with statistical matching procedures based on the conditional independence (CIA) assumption.
The aim of this paper is to present a method to combine information coming from different databases relaxing the CIA assumption. In particular we propose a method to combine household income and expenditure data under logical constraints regarding the average propensity to consume. We also propose an estimate of a plausible joint distribution function for household income and expenditure.Statistical matching and uncertainty analysis in combining household income and expenditure dataAbstracthttp://www.bancaditalia.it/pubblicazioni/temi-discussione/2015/2015-1018/index.html?com.dotmarketing.htmlpage.language=1Full texthttp://www.bancaditalia.it/pubblicazioni/temi-discussione/2015/2015-1018/en_tema_1018.pdf?language_id=1Pier Luigi ContiDaniela MarellaAndrea NeriPier Luigi Conti, Daniela Marella and Andrea Neri2015-07-15Bank of Italy Working PapersC14C15Covariate-augmented unit root tests with mixed-frequency data

Craig and Peter RaupachCentrality-Based Capital Allocations2015-06-01T12:33:00ZWe look at the effect of capital rules on a banking system that is connected through correlated credit exposures and interbank lending. Keeping total capital in the system constant, the reallocation rules, which combine individual bank characteristics and interconnectivity measures of interbank lending, are to minimize a measure of system-wide losses. Using the detailed German credit register for estimation, we find that capital rules based on eigenvectors dominate any other centrality measure, saving about 15 percent in expected bankruptcy costs.Centrality-Based Capital AllocationsAbstracthttp://www.ijcb.org/journal/ijcb15q3a8.htmFull texthttp://www.ijcb.org/journal/ijcb15q3a8.pdfAdrian AlterBen CraigPeter RaupachAdrian Alter, Ben R.

European Central Bank Working papers by Rudolf Alvise Lennkh, Florian WalchCollateral damage? Micro-simulation of transaction cost shocks on the value of central bank collateral2015-05-22T12:37:00ZTransaction cost shocks in financial markets are known to affect asset prices. This paper analyses how changes in transaction costs may affect the value of assets that banks use to collateralise borrowings in monetary policy operations. Based on a simple asset pricing model and employing a dataset of hypothetical Eurosystem collateral positions, we simulate and quantify the resulting change in collateral value pledged by counterparties to the Eurosystem, resulting from a transaction cost shock. A 10 basis point increase in transaction costs entails a direct -0.30% decrease of collateral value and a -0.07% decrease when adjusted for the expected reduction in the number of trades of each asset. We conclude that banks will on average suffer small collateral losses while selected institutions could face a considerably larger collateral decrease.Collateral damage?

SzerszenBayesian Estimation of Time-Changed Default Intensity Models2015-04-13T12:33:59ZGordy and Pawel J. Szerszen. We estimate a reduced-form model of credit risk that incorporates stochastic volatility in default intensity via stochastic time-change. Our Bayesian MCMC estimation method overcomes nonlinearity in the measurement equation and state-dependent volatility in the state equation. We implement on firm-level time-series of CDS spreads, and find strong in-sample evidence of stochastic volatility in this market. Relative to the widely-used CIR model for the default intensity, we find that stochastic time-change offers modest benefit in fitting the cross-section of CDS spreads at each point in time, but very large improvements in fitting the time-series, i.e., in bringing agreement between the moments of the default intensity and the model-implied moments. Finally, we obtain model-implied out-of-sample density forecasts via auxiliary particle filter, and find that the time-changed model strongly outperforms the baseline CIR model.Bayesian Estimation of Time-Changed Default Intensity ModelsAbstracthttp://www.federalreserve.gov/econresdata/feds/2015/index.htm#2015002Full texthttp://www.federalreserve.gov/econresdata/feds/2015/files/2015002pap.pdfPawel J.

Reserve Bank of Australia Research Discussion Papers by Tom BilstonStress Testing the Australian Household Sector Using the HILDA Survey2015-03-09T06:17:00ZIn Australia, the banking sector's substantial exposure to the household sector gives reason to continuously assess the financial resilience of households. In this paper, we further explore the simulation-based household stress-testing model presented in Bilston and Rodgers (2013). This model uses data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey to quantify the household sector's financial resilience to macroeconomic shocks. The model suggests that through the 2000s the household sector remained resilient to scenarios involving asset price, interest rate and unemployment rate shocks, and the associated increases in household loan losses under these scenarios were limited. Indeed, the results suggest that, despite rising levels of household indebtedness in aggregate, the distribution of household debt has remained concentrated among households that are well placed to service it. In turn, this suggests that aggregate measures of household indebtedness may be misleading indicators of the household sector's financial fragility. The results also highlight the potential for expansionary monetary policy to offset the effects of increases in unemployment and decreases in asset prices on household loan losses.Stress Testing the Australian Household Sector Using the HILDA SurveyFull texthttp://www.rba.gov.au/publications/rdp/2015/pdf/rdp2015-01.pdfTom BilstonTom Bilston2015-03Reserve Bank of Australia Research Discussion PapersC15D31Centrality-based capital allocations

Kansas City Fed Working Papers by Thealexa Becker and Didem TüzemenSelf-Employment and Health Care Reform: Evidence from Massachusetts2014-11-27T06:17:59ZWe study the effect of the Massachusetts health care reform on the uninsured rate and the self-employment rate in the state. The reform required all individuals to obtain health insurance, required most employers to offer health insurance to their employees,
formed a private marketplace that offered subsidized health insurance options and expanded public insurance. We examine data from the Current Population Survey (CPS) for 1994-2012 and its Annual Social and Economic (ASEC) Supplement for 1996-2013.
We show that the reform led to a dramatic reduction in the state's uninsured rate due to increased enrollment in both public and private health insurance. Estimation results from difference-in-differences models and the synthetic control method indicate that
the aggregate self-employment rate was higher in the state after the implementation of the reform. We conclude that easier access to health insurance encouraged self-employment in Massachusetts. There are many similarities between the Massachusetts
health care reform and the national health care reform, the Patient Protection and Affordable Care Act (PPACA). Based on Massachusetts' experience, the PPACA will lower the national uninsured rate and may lead to a higher self-employment rate in the nation.Self-Employment and Health Care Reform: Evidence from MassachusettsFull texthttp://www.kansascityfed.org/publicat/reswkpap/pdf/rwp14-16.pdfDidem TüzemenThealexa BeckerThealexa Becker and Didem Tüzemen2014-11Kansas City Fed Working PapersC10C15E24I13I18I38L26Estimating (Markov-Switching) VAR Models without Gibbs Sampling: A Sequential Monte Carlo Approach

Cleveland Fed Working papers by Mark J Bognanni and Edward HerbstEstimating (Markov-Switching) VAR Models without Gibbs Sampling: A Sequential Monte Carlo Approach2014-11-11T06:21:59ZVector autoregressions with Markov-switching parameters (MS-VARs) offer dramatically better data fit than their constant-parameter predecessors. However, computational complications, as well as negative results about the importance of switching in parameters other than shock variances, have caused MS-VARs to see only sparse usage. For our first contribution, we document the effectiveness of Sequential Monte Carlo (SMC) algorithms at estimating MSVAR posteriors. Relative to multi-step, model-specific MCMC routines, SMC has the advantages of being simpler to implement, readily parallelizable, and unconstrained by reliance on convenient relationships between prior and likelihood. For our second contribution, we exploit SMC?s flexibility to demonstrate that the use of priors with superior data fit alters inference about the presence of time variation in macroeconomic dynamics. Using the same data as Sims, Waggoner, and Zha (2008), we provide evidence of recurrent episodes characterized by a flat Phillips Curve.Estimating (Markov-Switching) VAR Models without Gibbs Sampling: A Sequential Monte Carlo ApproachFull texthttp://www.clevelandfed.org/research/workpaper/2014/wp1427.pdfEdward HerbstMark J BognanniMark J Bognanni and Edward Herbst2014-11Cleveland Fed Working papersC11C15C32C52E3E4E5Carry Trade Activities: A Multivariate Threshold Model Analysis

Swiss National Bank Working Papers by Matthias GublerCarry Trade Activities: A Multivariate Threshold Model Analysis2014-11-04T12:31:59ZIn this empirical study, we analyze the relationship between carry trade positions and some key financial as well as macroeconomic variables using a multivariate threshold model. It is often stated that the Swiss franc serves as a funding currency. We therefore focus on carry trades based on the USD/CHF and EUR/CHF currency pairs over the period from 1995 to mid-2008. We conclude that carry trades are driven to a large extent by changes in investors' risk sentiment, movements in stock market prices and exchange rate fluctuations. The adjustments of carry trade positions to unexpected movements in these variables vary between periods of high and low interest-rate differentials (IRD). While a positive shock to the IRD is followed by a rise in carry trade positions during a period of low IRD, it will trigger a decline in these positions during a period of high IRD. These results suggest that the shock to the IRD itself is not enough to compensate investors for the increased foreign exchange risk. Moreover, a positive stock market price shock is associated with a rise in carry trade positions, since investors may use stock portfolios as collateral for liquidity. A sudden unwinding of carry trades leads to significant Swiss franc appreciation. Furthermore, carry trade activities 'Granger-cause' the nominal exchange rate in periods of low IRD. The Granger causality test results further indicate feedback trading.Carry Trade Activities: A Multivariate Threshold Model AnalysisFull texthttp://www.snb.ch/n/mmr/reference/working_paper_2014_06/source/working_paper_2014_06.n.pdfMatthias GublerMatthias Gubler2014-11-04Swiss National Bank Working PapersC15C32E44
