Heterogeneity in Mortgage Refinancing

By Julia Wu

Abstract
Many households who would benefit from and are eligible to refinance their mortgages fail to do so. A recent literature has demonstrated a significant degree of heterogeneity in the propensity to refinance across various dimensions, yet much heterogeneity is left unexplained. In this paper, I use a clustering regression to characterize heterogeneity in mortgage refinancing by estimating the distribution of propensities to refinance. A key novelty to my approach is that I do so without relying on borrower characteristics, allowing me to recover the full degree of heterogeneity, rather than simply the extent to which the propensity to refinance varies with a given observable. I then explore the role of both observed and unobserved heterogeneity in group placement by regressing group estimates on a set of demographic characteristics. As a complement to my analysis, I provide evidence from a novel dataset of detailed information on borrower perspectives on mortgage refinancing to paint a more nuanced picture of how household characteristics and behavioral mechanisms play into the decision to refinance. I find a significant degree of heterogeneity in both the average and marginal propensity to refinance across households. While observables such as education, race and income do significantly correlate with group heterogeneity, it is clear that much heterogeneity may still be attributed to the presence of unobservable characteristics.

Where Did the Money Go? Impact of the ECB’s Corporate Sector Purchase Program on Eurozone Corporate Spending

By Tina Tian   

Slow corporate growth and a lack of corporate investment has plagued European markets for the past decade. As a response, the ECB began the Corporate Sector Purchase Program (CSPP) in 2016 to provide liquidity to corporate debt markets through bond purchases. Four years after the start of the program, this paper assesses its impact by looking at how companies spent this money on a micro level. In particular, it looks at the impact of long-term debt on five expenditures (fixed assets and R&D, cash balances, short-term debt, cash to shareholders, and share buybacks). We test these hypothesized expenditures based on financial statement panel data from a selection of European firms whose bonds were purchased by the ECB. The results show an increase in financial expenditures including cash balances and short-term debt and a decrease in productive investment expenditures such as fixed assets and R&D. This indicates a lack of efficacy of the corporate bond purchase program as excess liquidity provided by the ECB went towards eurozone companies refinancing existing debt rather than investing in growth ventures.

Immigrant Workers in a Changing Labor Environment: A study on how technology is reshaping immigrant earnings

By Grace Peterson

This research determines how automation affects immigrant wages in the US and how closely this impact follows the skills-biased technical change (SBTC) hypothesis. The present study addresses this question using American Community Survey (ACS) data from 2012 to 2016 and a job automation probability index to explain technological change. This research leverages OLS regressions to evaluate real wage drivers, grouping data by year, immigration status, and education level. According to the SBTC hypothesis, high skill immigrant wages should be less negatively affected by technological change than low skill immigrant wages. Univariate analysis suggests that the SBTC hypothesis is even stronger for US = immigrants than native-borns, as high skill immigrants have a lower average probability than low skill immigrants of having their jobs automated, and the difference in effect on high versus low skilled workers is larger for immigrant than native-borns. However, multivariate analysis asserts that technological change affects low skill immigrants’ wages less than high skilled individuals’ wages, which counters the SBTC hypothesis.

Overreaction in the Financial Times Stock Exchange (FTSE)

By Yusuke Ewan Tanaka Legard

The Overreaction Hypothesis suggests that investors overreact to unexpected news in the financial world, which leads to a mispricing of equities. This paper investigates the presence of overreaction in the Financial Times Stock Exchange (FTSE) between 1995 and 2018. The empirical methodology studies the monthly returns of equities in the FTSE 100. The empirical results are consistent with the overreaction hypothesis and indicate the presence of overreaction within the FTSE. Furthermore, the results highlight whether the information revolution has exacerbated or lessened overreaction. The results suggest that investor overreaction has not altered, for better or worse, since the information revolution.

The Impact of a Fixed Exchange Rate Regime on Growth and Volatility in an Oil-­‐‑dependent Economy

By Shihab Osman Malik and Faisal Bandar Alsaadi 

This study examines the relationship between the fixed exchange rate regime, economic growth, and output volatility in oil-­‐‑producing Saudi Arabia over the post-­‐‑Bretton Woods period (1973–2016). We assess the implications of the current exchange rate regime on macroeconomic and growth performance, and evaluate its sustainability in the context of oil-­‐‑dependency and market dynamics. We develop and employ a theoretical framework and empirical specification based on previous literature to find that for Saudi Arabia, the fix is associated with faster growth and lower output volatility. We believe the result is primarily driven by the credibility of the fix in terms of establishing a strong nominal anchor and monetary policy framework.

What Fosters Innovation? A CrossSectional Panel Approach to Assessing the Impact of Cross Border Investment and Globalization on Patenting Across Global Economies

By Michael Dessau and Nicholas Vega

This study considers the impact of foreign direct investment (FDI) on innovation in high income, uppermiddle  income and lowermiddle income countries. Innovation matters because it is a critical factor for economic growth. In a panel setting, this study assesses the degree to which FDI functions as a vehicle for innovation as proxied by scaled local resident patent applications. This study considers research and development (R&D), domestic savings, imports and exports, and quality of governance as factors which could also impact the effectiveness of FDI on innovation. Our results suggest FDI is most effective as inward direct investment in countries outside the technological frontier possessing adequate existing domestic investment capital and R&D spending to convert foreign investment capital and technological spillover into innovation. Nonetheless, FDI was not a consistent indicator for innovation; rather, the most consistent indicators across this study were R&D and domestic savings. Differences amongst income groups are highlighted as well as their varying responses to our array of causal factors.

Modeling Variation in U.S. Bank Holding Companies’ Net Interest Margins

By Daniel Dorchuck

This study explores variation in US bank holding companies’ (BHCs) net inter-est margins (NIMs) and the effects of interest rate risk exposure on NIMs. Interest rate risk (IRR) is intrinsic in maturity transformation and financial intermediation as banks take on short-term liabilities in the form of deposits and create assets in the form of loans with longer maturities and different repricing profiles. Accordingly, interest rate risk is necessary for bank holding companies (BHCs) to be profitable in financial intermediation, and net interest margins are chosen as a variable of inter-est because they are an isolated measure of bank’ profitability from interest earning assets. Naturally, BHCs employ maturity pairing and derivative hedging to mitigate IRR and ultimately increase and smooth earnings. Synthesizing banks’ balance sheet and income statement data, macroeconomic variables, credit conditions, and interest rate environment variables, this study hopes to expand on existing work by provid-ing insight on the determinants of NIMs as well as interest rate derivatives’ efficacy in increasing and stabilizing net interest margins. The models presented establish links between long term rate exposure, risk-averse capital positions, and increased margins. Additionally, the models suggest that banks earn smaller spreads (NIMs) in higher interest rate environments but benefit from steeper yield curves.

Proposing an Alternative to the European Central Bank’s Fiscal Convergence Criteria

By Junaid Arefeen

The recent onset of the sovereign debt crisis in the Eurozone has brought the viabil-ity of the Eurozone as a currency area into question. The unsustainable debt and deficit balances accumulated by several Eurozone nations since the adoption of the common currency in 1999, and the consequent incidence of high levels of sovereign default risk in the euro-area, indicate that the fiscal convergence criteria employed by the European Central Bank to monitor the fiscal discipline and sustainability of its members have been largely ineectual. This paper draws upon the theory of optimum currency areas, and proposes a set of business cycle convergence criteria that can be employed as an alternate means to minimize the risk of fiscal imbalances and sovereign default. Economic theory suggests that a currency union with convergent business cycles will be insulated from asymmetric shocks, removing the need for countries to rely wholly on their fiscal policies when dealing with negative shocks (as would be the case in a currency union with non-synchronous countries suering from negative asymmetric shocks). Therefore, as the risk of fiscal imbalances is minimized, a currency union with synchronous business cycles is expected to have low incidences of sovereign default risk. This paper tests this economic intuition empirically, and employs a multivariable panel regression model to determine the relationship between business cycle convergence and sovereign default risk (proxied using sovereign yield spreads). The regressions reveal that the degree of business cycle convergence is one of the main determinants of yield dierentials, and the relationship between the two is negative (as expected). The consistency of the results to numerous robustness checks provide a strong case for substituting the current fiscal convergence criteria with measures that assess the degree of business cycle convergence.

Inflation Volatility and Economic Growth: A Disaggregated Analysis

By Nicholas Becker

Inflation volatility has been theorized to negatively affect real economic growth, but empirical analyses have returned somewhat mixed results. Constructing my own dataset of household group inflation rates by disaggregating and linking Consumer Expenditure Survey data with Consumer Price Index data, I analyze inflation volatility and economic growth from the ground-up. Calculating inflation volatility using a moving-window methodology, I find: 1) significant heterogeneity of inflation volatility across household groups; 2) a negative correlation between inflation volatility and economic growth from 2000-2012 for all household groups, with a stronger negative correlation at lower income levels; 3) a positive correlation between volatility and growth during expansions and a negative correlation between volatility and growth during recessions. Results suggest reducing inflation volatility and refining policymaking to account for the heterogeneity of inflation volatility could improve growth over the longrun. Further analysis is warranted.

Understanding the Argentine Peso’s Devaluation in 2014 —Analysis on Argentina’s Fiscal Sustainability from 1993 to 2013

By Feng Pan

This research analyzes the fiscal sustainability of Argentina from 1993 to 2013. Specifically, it explains the peso devaluation in early 2014 and suggests that it is primarily due to the fundamental problems in Argentina’s economy. This paper highlights Argentina’s inability to enhance its fiscal conditions and suggests possible future economic developments in Argentina. This paper concludes that there is high
chance of hyperinflation, debt default, and the eventual dissolution of the managed exchange rate regime in Argentina in the future.
