a machine learning approach to identifying different types of uncertainty abstract we implement natural language processing techniques to extract uncertainty measures from federal reserve beige books between 1970 and 2018 business and economic related uncertainty is associated with future weakness in output higher unemployment and elevated term premia on the other hand political and government uncertainty while high during recent times has no statistically significant impact on the economy

could a monetary base rule have prevented the great depression abstract this paper continues an ongoing investigation of the properties of a policy rule that specifies settings of the monetary base that are designed to keep nominal gnp growing smoothly at a noninflationary rate counterfactual historical simulations for 1923 1941 are conducted with the rule and a small model of nominal gnp determination estimated with u s quarterly data with residuals fed in as estimates of the behavioral shocks that occurred the simulation results indicate that nominal gnp would have been kept reasonably close to a steady three percent path over 1923 1941 if the rule had been in effect

price and quantity endogeneity in demand analysis evidence from directed acyclic graphs we propose to use the emerging method of directed graphs to study price quantity endogeneity issues in empirical demand analysis the approach is illustrated through the examination of u s meat consumption we find that for two major meat products beef and poultry retail prices contemporaneously caused quantities consumed thus were predetermined in contrast the quantity consumed of pork appeared to be predetermined relative to its price

the effects of economic policy uncertainty on china s economy evidence from time varying parameter favar this article explores the effects of china s economic policy uncertainty epu on its fiscal policy monetary policy and a wide range of macro economic variables using a time varying parameter fava

time frequency characterization of the u s financial cycle despite an increase in research motivated by the global financial crisis of 2007 08 empirical studies on the financial cycle are rare compared to those on the business cycle this paper adds some new evidence to this scarce literature by using a different empirical methodology wavelet analysis to extract financial cycles from the data our results confirm that the u s financial cycle is much longer than the business cycle but we do not find strong evidence supporting the view that the financial cycle has lengthened during the great moderation period

large shocks in the volatility of the dow jones industrial average index 1928 2013 we determine the events that cause large shocks in volatility of the djia index over the period 1928 2013 using a new semi parametric test based on conditional heteroscedasticity models we find that these large shocks can be associated with particular events financial crashes elections wars monetary policies etc we show that some shocks are not identified as extraordinary movements by the investors due to their occurring during high volatility episodes especially the 1929 1934 1937 1938 and 2007 2011 periods

analyzing the time frequency lead lag relationship between oil and agricultural commodities abstract we analyze the time frequency co movement of and lead lag relationship between price indices of oil and 21 agricultural commodities and attempt to identify the leader and follower among the considered price indices for the 1980m1 2017m5 period the empirical analysis is conducted using four wavelet tools wavelet coherency phase difference multiple correlation and multiple cross correlation the first two tools are used to identify the time frequency co movement of and lead lag relationship between price indices of oil and 21 agricultural commodities and the third and fourth tools are used to identify the leader and follower among all series of price indices across different scales our results on wavelet coherency show a high degree of co movement at a long run horizon for the entire period between the price indices of oil and coal cotton fishmeal maize rice rubber and wheat furthermore the connection between these commodity markets and the oil market strengthened after 2000 indicating the importance of financial crisis phenomena and geopolitical turbulence additional findings show that short run investors should invest in the beef and swine pork markets as they have very little correlation with the oil markets the results of multiple correlation and multiple cross correlation analysis show that the coffee price was leader or follower across all time scales except wavelet scale 16 where barely was a leader or a follower

commodity price changes and the predictability of economic policy uncertainty in this study we forecast economic policy uncertainty epu using input on 23 commodity price changes we reveal the significant predictability of epu using three forecast combinations this indicates that commodity price changes can be taken as a leading indicator of epu

decomposition and additivity in price dependent demand systems price dependent inverse demand functions theoretical discussions of price dependent systems are provided by weymark and anderson this paper further explores the theory of price dependent systems providing two new theoretical results first there are symmetric and nonsymmetric decompositions of the quantity effect on prices second direct and indirect additivity have different implications for price dependent systems both theoretical results are tested with data on agricultural products

the time varying correlation between uncertainty output and inflation evidence from a dcc garch model abstract using a new uncertainty index from baker et al 2012 we evaluate the time varying correlation between macroeconomic uncertainty inflation and output estimation results from a multivariate dcc garch model reveal that the sign of the correlation between macroeconomic uncertainty and inflation changed from negative to positive during the late 1990s whereas the correlation between uncertainty and output is consistently negative

directional predictability from oil market uncertainty to sovereign credit spreads of oil exporting countries evidence from rolling windows and crossquantilogram analysis abstract given the recent collapse of oil prices this study investigates the directional predictability from the oil market uncertainty to the sovereign credit default swap cds spreads of four oil exporting gcc countries bahrain qatar saudi arabia and united arab emirates and five other oil exporting countries brazil mexico norway russia and venezuela using the modified bootstrap rolling window approach the empirical results reveal a significant directional predictability from oil uncertainty to the cds spreads of most of those oil exporting countries during the subperiods 2010 2011 and 2014 2015 that is during the periods when oil volatility follows a rising trend the most significant directional predictability is found for qatar bahrain saudi arabia and norway particularly during the 2014 2015 oil price collapse subperiod whereas there is no directional predictability found in the case of brazil for mexico the oil market uncertainty predicts cds spreads mostly during 2014 and for venezuela the directional predictability flows are highly impactful and concentrated during 2011 13 to check the robustness of our estimations we use a novel quantile dependence measure called the cross quantilogram that was developed by han et al 2016 the estimation results of this approach confirm our main findings and indicate that the surge in oil volatility predicts the cds spreads in different quantiles overall the findings highlight that the sovereign credit risk of the gcc and the other oil exporting countries is at least partially driven or directionally predicted by the oil volatility shocks this has important implications for investment and policy decisions

sources of panics evidence from the weekly data abstract we use weekly data 1867 1933 to investigate the sources of banking and financial panics we find that while a panic s exact starting date is unpredictable one can identify environments conducive to panics a lack of liquidity in financial markets seems to be a key source results also reveal the effectiveness of the aldrich vreeland act inelastizing the money supply and shortening the panic of 1914 and suggest that the panic of 1933 may have been caused by a speculative attack on the gold backed us dollar via the banks as opposed to a run on the banks directly

is the relationship between gold and the u s dollar always negative the role of macroeconomic uncertainty abstractthe main work of this article is to access the role of macroeconomic uncertainty in effecting the correlation between gold and the dollar the empirical analysis is divided into two parts firstly we examine the impact of macroeconomic uncertainty on short and long correlation between gold and the dollar secondly we analyse the explanatory power of economic uncertainty for the abnormal market relation between gold and the dollar with a threshold model in particular we investigate impacts of economic uncertainty sourced from different economies the empirical results indicate that economic uncertainty generates direct impacts on the correlation between gold and the dollar moreover our results emphasize that uncertainty sourced from different economies have different impacts on the dynamics between gold and the dollar this article also presents the relative contribution of gold and the dollar shocks to the likelihood of being in the high uncertainty regime these results have implications fo

the role of news based implied volatility among us financial markets we investigate the role of uncertainty measured by news based implied volatility in anticipating us long term market volatilities from a garch midas model we find that news based implied volatility performs well in predicting long term aggregate market volatilities a subsample analysis provides that the predictive power of news based implied volatility is decreasing

risk shocks and housing supply a quantitative analysis this paper analyzes the role of stochastic uncertainty in a multi sector housing model with financial frictions we include time varying uncertainty i e risk shocks in the technology shocks that affect housing production and provide estimates of the time series properties of risk shocks by using firm level productivity data the analysis demonstrates that risk shocks to the housing production sector are a quantitatively important impulse mechanism for understanding housing price movements specifically the model can match the volatility of housing prices observed in the data it is also demonstrated that adjustment costs are important in replicating the contemporaneous correlation of housing prices with gdp and residential investment critically bankruptcy costs act as an endogenous markup factor in housing prices and are an important determinant of house price volatility however in comparison to housing demand shocks risk shocks have low explanatory power for real quantities

dynamic connectedness of uncertainty across developed economies a time varying approach abstract economic uncertainty has attracted a significant part of the modern research in economics proving to be a significant factor for every economy in this study we focus on the transmission channel of uncertainty between developed economies examining potential spillover effects between the u s the e u the u k japan and canada within a time varying framework our empirical results indicate of a significant spillover of uncertainty from the e u to the u s

international economic policy uncertainty and stock prices revisited multiple and partial wavelet approach abstract this paper introduces a new dimension to the relationship between economic policy uncertainty epu and stock prices sp by extending the contributions of ko and lee 2015 by using multiple and partial wavelet coherence techniques the vulnerability of sp due to combined and isolated impact of international us epu and domestic policy uncertainty depu is investigated the main findings are a the combined effect of depu and us epu is more significant for developed market s sp b the emerging market s sp are more sensitive to depu and c amongst developed markets japan and european countries are more sensitive to us epu than depu

economic policy uncertainty shocks and stock bond correlations evidence from the us market abstract this paper examines the effects of economic policy uncertainty shocks on stock bond correlations for the us market we devise a general framework which distinguishes a positive shock from a negative one and nests either as its special case the results show that innovations in the policy uncertainty index impact negatively and asymmetrically on the subsequent stock bond correlations which are characterized by a structural break and positive type asymmetry

dynamic co movements of stock market returns implied volatility and policy uncertainty we examine time varying correlations among stock market returns implied volatility and policy uncertainty our findings suggest that correlations are indeed time varying and sensitive to oil demand shocks and us recessions

on the different approaches of measuring uncertainty shocks as uncertainty has become an increasingly prominent source of business cycle fluctuations various uncertainty proxies have been proposed in the literature this paper shows that uncertainty measures based on realized variables fluctuate more than the measures that are based on forecasts more precisely the variation in the realized cross sectional standard deviation of profit growth and stock returns is larger than the variation in the forecast standard deviation moreover the forecast standard deviation of profit growth and stock returns are negatively or uncorrelated the uncertainty measures increase stock returns due to a risk premium but they decrease profit growth

cross country determinants of economic policy uncertainty spillovers this study explores the determinants of cross country economic policy uncertainty epu spillovers we find that bilateral factors such as trade and common language play a highly significant role i

is there a role for uncertainty in forecasting output growth in oecd countries evidence from a time varying parameter panel vector autoregressive model this paper uses a time varying parameter panel vector autoregressive tvp pvar model to analyze the role played by domestic and us news based measures of uncertainty in forecasting the growth of industrial production of 12 organisation for economic co operation and development oecd countries based on a monthly out of sample period of 2009 06 to 2017 05 given an in sample of 2003 03 to 2009 05 there are only 46 of cases where domestic uncertainty can improve the forecast of output growth relative to a baseline monetary tvp pvar model which includes inflation interest rate and nominal exchange rate growth besides output growth moreover including us uncertainty does not necessarily improve the forecasting performance of output growth from the tvp pvar model which includes only the domestic uncertainty along with the baseline variables so in general while uncertainty is important in predicting the future path of output growth in the 12 advanced economies considered a forecaster can do better in majority of the instances by just considering the information from standard macroeconomic variables

the inverse almost ideal demand system abstract a new demand system related to the almost ideal demand system aids of deaton and muellbauer is developed and illustrated this inverse aids iaids retains all of the desirable theoretical properties of the aids model with the exception of consistent aggregation an empirical issue is whether a linear approximation will work as well for the iaids as it has for the aids model since quantities are not as highly correlated as prices an application to u s meat demand demonstrates that the linear approximation of the iaids is excellent which enhanced the ease and range of application

long memory economic policy uncertainty and forecasting us inflation a bayesian varfima approach abstractwe compare inflation forecasts of a vector autoregressive fractionally integrated moving average varfima model against standard forecasting models u s inflation forecasts improve when controlling for persistence and economic policy uncertainty epu importantly the varfima model comprising of inflation and epu outperforms commonly used inflation forecast models

time frequency causality and connectedness between international prices of energy food industry agriculture and metals abstract this study analyzes the lead lag relationship between the price indices of energy fuels and each of food industrial inputs agriculture raw materials metals and beverages in the time frequency domain to this end we first use the wavelet coherency and phase differences next we use the diebold and yilmaz 2012 and barunik and krehlik 2017 spillover indices to analyse the connectedness among the set of the price indices under consideration the period of the study is 1990m1 to 2017m5 the wavelet coherency results reveal that there are important and significant relations between the fuel and food prices the fuel and industrial prices and the fuel and metal prices these results also show that there are phase relationships between those paired prices the volatility spillover results indicate that the agricultural sector is the most affected by shocks from the other markets the return series of the industrial input prices at all frequencies appears to be the main source of volatility transmission to the prices of the other commodities over the whole period this finding underlines the relevance of the industrial inputs to policy makers particularly when they design policies to provide incentives related to industrial production

unconventional monetary policy and the credit channel in the euro area abstract we disentangle credit supply and demand and we then embed this information into a bayesian threshold var model to investigate the importance of the demand channel and the broad credit channel in the transmission of unconventional monetary policy on the macroeconomy during financial stress periods we find that during such periods ump shocks boost aggregate demand for loans increase agents net worth and revitalize credit to firms and households in addition counterfactual analysis suggests that non standard policy measures aiming at stimulating loan demand and relaxing banks balance sheet constraints would provide a significant support to economic activity prices and the financial sector

should the euro area be run as a closed economy the european economic and monetary union emu has created a new economic area larger and closer with respect to the rest of the world area specifi cs hocks are thus more important in emu than country specific shocks used to be in the previous states e g in germany it is thus not surprising that the models used to determine optimal monetary policy in the euro area for instance smets and wouters 2004 assume that this works essentially as a closed economy hit by domestic shocks i e the same assumption made in standard models of u s monetary policy see e g christiano et al 1999 where all shocks are domestic with the only possible exception of energy price shocks this paper studies monetary policy in the euro area looking at the variable most directly related to current and expected monetary policy the yield on long term government bonds we explore how the behaviour of european long term rates has been affected by emu and whether the response of long term rates to monetary policy has got any closer to that consistent with a closed economy we find that the level of long term rates in europe is almost entirely explained by u s shocks and by the systematic response of u s and european variables to these shocks the systematic component of european monetary policy responds to u s variables more than it does to local variables this was true for the bundesbank before emu and remains true for the ecb since the start of emu we also find that unpredictable fluctuations in long term rates are driven by shocks to term premia not to monetary policy this means that the ecb can affect long rates only through the systematic component of its monetary policy which as we have seen mostly responds to u s variables monetary policy shocks induced by the ecb have virtually no effect on long rates claiming that monetary policy in the euro area can be determined as if the region were a closed economy is thus not consistent with the empirical evidence on

forms of scale curves and differential inverse demand systems this article provides a new interpretation of the scale effects in differential inverse demand systems a scale curve is defined as a curve that shows how the expenditure share of a good or service changes as the consumption level changes it is shown that brown lee and seale s synthetic model has the same scale effects as do the box cox scale curves in this light their model is not a mere composite but a model in its own right an empirical illustration given for japanese fresh food demand suggests that the underlying scale curves differ from both linear and loglinear forms

economic policy uncertainty in the us does it matter for the euro area abstract we investigate the effects of a us economic policy uncertainty shock on some euro area macroeconomic aggregates via structural vars we model the indicators of economic policy uncertainty recently developed by baker et al 2013 jointly with the aggregate price indexes and alternative indicators of the business cycle for the two above indicated economic areas according to our svars a one standard deviation shock to us economic policy uncertainty leads to a statistically significant fall in the european industrial production and prices of 0 12 and 0 06 respectively the contribution of the us uncertainty shock on the european aggregates is shown to be quantitatively larger than the one exerted by an euro area specific uncertainty shock

the federal reserve and panic prevention the roles of financial regulation and lender of last resort this paper surveys the role of the federal reserve within the financial regulatory system with particular attention to the interaction of the fed s role as both a supervisor and a lender of last resort the institutional design of the federal reserve system was aimed at preventing banking panics primarily due to the permanent presence of the discount window this new system was successful at preventing a panic in the early 1920s after which the fed began to discourage the use of the discount window and intentionally create stigma for window borrowing policies that contributed to the panics of the great depression the legislation of the new deal era centralized fed power in the board of governors and over the next 75 years the fed expanded its role as a supervisor of the largest banks nevertheless prior to the recent crisis the fed had large gaps in its authority as a supervisor and as lender of last resort with the latter role weakened further by stigma the fed was unable to prevent the recent crisis during which its lender of last resort function expanded significantly as the fed begins its second century there are still great challenges to fulfilling its original intention of panic prevention

measuring financial asset return and volatility spillovers with application to global equity markets we provide a simple and intuitive measure of interdependence of asset returns and or volatilities in particular we formulate and examine precise and separate measures of return spillovers and volatility spillovers our framework facilitates study of both non crisis and crisis episodes including trends and bursts in spillovers and both turn out to be empirically important in particular in an analysis of sixteen global equity markets from the early 1990s to the present we find striking evidence of divergent behavior in the dynamics of return spillovers vs volatility spillovers return spillovers display a gently increasing trend but no bursts whereas volatility spillovers display no trend but clear bursts

on the cyclicity of regional house prices new evidence for u s metropolitan statistical areas abstract this paper is mainly concerned with the analysis of regional house price cycles we introduce a wavelet transform based metric to study the housing cycle synchronization across the largest u s msas with a focus on the recent housing bubble we derive several conclusions i we show that regional housing cycle dissimilarities are significantly and strongly connected to geography ii after the burst of the recent housing bubble there was greater significant co movement in shorter cycles for a short period of time iii coastal regions which have a higher house price volatility compared to other msas are also those with a higher degree of house supply regulation iv a mortgage rate reduction decrease the dissimilarity between the msas and the national housing cycle before the end of 2006 at higher frequencies hence monetary policy is partially effective whereas effectiveness depends on time frequency and the considered msa

the reconstruction finance corporation the gold standard and the banking panic of 1933 the banking crisis of 1933 which forced a national holiday closing the entire u s financial system is often blamed on either publication of the names of banks borrowing from the reconstruction finance corporation a speculative run on the gold backed dollar due to fears that president elect roosevelt would devalue the currency or both evidence presented here indicates that neither factor started the final banking crisis of the depression the michigan bank holiday ignited the panic resulting in a series of bank holidays and a run on the dollar this chain of events toppled the united states financial system

fluctuations in uncertainty this review article tries to answer four questions i what are the stylized facts about uncertainty over time ii why does uncertainty vary iii do fluctuations in uncertainty matter and iv did higher uncertainty worsen the great recession of 2007 2009 on the first question both macro and micro uncertainty appears to rise sharply in recessions on the second question the types of exogenous shocks like wars financial panics and oil price jumps that cause recessions appear to directly increase uncertainty and uncertainty also appears to endogenously rise further during recessions on the third question the evidence suggests uncertainty is damaging for short run investment and hiring but there is some evidence it may stimulate longer run innovation finally in terms of the great recession the large jump in uncertainty in 2008 potentially accounted for about one third of the drop in gdp

macroeconomic policy uncertainty shocks on the chinese economy a gvar analysis abstractthis article studies the spillovers of economic policy uncertainty epu from developed economies to china in terms of the source extent and persistence by estimating a global vector autoregressive gvar model with both financial and trade variables acting as the transmission channels our findings confirm the existence of international transmissions of policy uncertainty while the patterns differ markedly the us epu appears to be the most significant cause of the fall of export industrial production equity price and exchange rate meanwhile the eu epu is also to be blamed for the depreciation of rmb in contrast to industrial production which shows the largest negative impact chinese inflation increases to a relatively smaller extent with the epu shocks ranking as the us japanese and the eu regardless of the minor impact on a long term interest rate the short term interest rate in china reacts positively to the european and us epu shocks despite the independent national monetary poli

uncertainty shocks and unemployment dynamics in u s recessions abstract what are the effects of uncertainty shocks on unemployment dynamics we answer this question by estimating non linear smooth transition vars with post wwii u s data the relevance of uncertainty shocks is found to be much larger than that predicted by standard linear vars in terms of i magnitude of the reaction of the unemployment rate to such shocks and ii contribution to the variance of the prediction errors of unemployment at business cycle frequencies the ability of different classes of dsge models to replicate our results is discussed

on the transmission mechanism of country specific and international economic uncertainty spillovers evidence from a tvp var connectedness decomposition approach abstract we investigate the internal and external categorical economic policy uncertainty epu spillovers between the us and japan using a novel extension of the tvp var connectedness approach of antonakakis and gabauer 2017 the decomposition of our approach gives us insights about the dynamics with and without international spillovers which has essential policy implications our results suggest that monetary policy uncertainty is the main driver followed by uncertainties associated with fiscal currency market and trade policies furthermore we find that the fukushima daiichi accident can be interpreted as a negative trade shock that spread internationally

measuring cross category spillovers of policy specific uncertainty in china abstract this paper examine cross category spillovers of policy specific uncertainty in china we find that monetary policy and exchange rate policy are net givers while fiscal policy and trade policy are net receivers monetary policy plays the dominant role spillovers are countercyclical

international economic policy uncertainty and stock prices wavelet approach this paper examines the link between economic policy uncertainty and stock price in both a time and frequency domain wavelet analysis reveals that the relationship is generally negative but changes over time exhibiting low to high frequency cycles moreover the timing of frequency changes overlaps when us policy uncertainty comoves with other countries policy uncertainty

assessing international commonality in macroeconomic uncertainty and its effects this paper uses a large vector autoregression var to measure international macroeconomic uncertainty and its effects on major economies using two datasets one with gdp growth rates for 19 industrialized countries and the other with a larger set of macroeconomic indicators for the u s euro area and u k using basic factor model diagnostics we first provide evidence of significant commonality in international macroeconomic volatility with one common factor accounting for strong comovement across economies and variables we then turn to measuring uncertainty and its effects with a large var in which the error volatilities evolve over time according to a factor structure the volatility of each variable in the system reflects time varying common global components and idiosyncratic components in this model global uncertainty is allowed to contemporaneously affect the macroeconomies of the included nations both the levels and volatilities of the included variables in this setup uncertainty and its effects are estimated in a single step within the same model our estimates yield new measures of international macroeconomic uncertainty and indicate that uncertainty shocks surprise increases lower gdp and many of its components adversely affect labor market conditions lower stock prices and in some economies lead to an easing of monetary policy

the international transmission of volatility shocks an empirical analysis this paper proposes an empirical model which can be used to estimate the international transmission of volatility shocks using this model we estimate that a one standard deviation increase in the volatility of the shock to us real gdp leads to a decline in uk gdp of 1 relative to trend and a 0 7 increase in uk cpi relative to trend at the two year horizon using a nonlinear open economy dsge model we find that these empirical estimates are consistent with the response to a perturbation to the volatility of foreign supply type shocks while an increase in the volatility of demand shocks has a negligible impact

international spillovers of policy uncertainty using the baker et al 2013 index of policy uncertainty for six developed countries this paper estimates spillovers of policy uncertainty we find that spillovers account for slightly more than one fourth of the dynamics of policy uncertainty in these countries with this share rising to one half during the financial crisis the us and uk are responsible for a large fraction of the spillovers since the financial crisis while the remaining countries are all net receivers of policy uncertainty shocks during and after this period
