Creditor concentration: An empirical investigation

Most of the literature on multiple banking assumes equal financing shares. However, unequal, asymmetric or concentrated bank borrowing is widespread, and creditor concentration is only weakly correlated with the number of bank relationships. This paper therefore investigates the determinants of creditor concentration for German firms using a comprehensive firm-bank level dataset for the time period between 1993 and 2003. We document that corporate borrowing from banks is very often concentrated, even for the largest firms in our sample. Leveraged firms and firms with more redeployable assets concentrate their borrowing from banks, as are firms dealing with a relationship lender that is profitable, that has lower monitoring costs, or that operates in a concentrated regional lending market.     

Commodity prices and growth: An empirical investigation

Whereas empirical evidence on the effect of higher commodity prices on the long-run growth of commodity exporters is ambiguous, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise income in the short run. In this paper we adopt panel error correction methodology to analyze global data for 1963 to 2008 to disentangle the short and long run effects of international commodity prices on output per capita. Our results show that commodity booms have unconditional positive short-term effects on output, but non-agricultural booms in countries with poor governance have adverse long-term effects which dominate the short-run gains. Our findings have important implications for non-agricultural commodity exporters with poor governance, especially in light of the recent wave of resource discoveries in low-income countries.     

Culture and labour productivity: An empirical investigation

Culture is considered as one of the most powerful forces that shape human behaviour and thereby economic activity. This paper investigates the effects of culture on labour productivity and examines the cultural traits driving this relationship. Using panel data analysis, empirical evidence is provided covering a sample of 34 OECD countries over a wide period of three decades. Our empirical results suggest a significant positive relationship between the cultural background and labour productivity. The main channels of this positive impact are control and work ethic environment, while obedience has a negative impact on productivity. These findings are robust to a series of robustness checks, including alternative cultural measures, additional control variables, various country samples, and alternative specifications.     

Aspiration level effects: An empirical investigation

Theories of aspiration level effects predict that decisions under uncertainty will depend on whether performance is above or below some target level of performance. A sample of 5000 quarterly earnings announcements by publicity held companies listed on the COMPUSTAT and CRSP data bases is examined to test this hypothesis. Four models from the current accounting literature are used as alternative estimates of the target level of earnings for these firms. When earnings are announced the difference between actual and forecast earnings, here called a forecast error, can be computed. The data indicate that the relationship between valuation and forecast error differs conditional on the sign of the forecast error.     

Relative prices and international competitiveness: An empirical investigation

This paper examines the relationship between competitive shares and relative prices for the exports of Japan, Korea and India over the past fifteen years. For Japan the results are consistent with neotechnological theories, and may be explained by a recently explicated model which applies the logic of Hicks' induced innovation mechanism to trade analysis. For the developing countries the results are found to be systematically associated with foreign trade regimes pursued as a part of overall development strategies. Thus the applicability of typical results derivable from standard static trade theories are found to be bound or restricted to special cases defined by stages of economic development, and by policy choices.     

Firm heterogeneity and trade-induced layoffs: An empirical investigation

We use a novel data set with verified observations of trade-induced layoffs by U.S. firms to study the interaction between firm productivity and trade liberalization as key determinants of firm-level job destruction due to trade. We find that patterns of trade-induced layoffs are broadly consistent with the predictions for firm-level employment generated by the Melitz (2003) heterogeneous firms theory – the number of trade-induced layoffs increases with firm productivity for non-exporting firms but decreases with firm productivity for exporting firms. The fact that exporting firms incur trade-induced layoffs at all invites a refined interpretation of the theory. Our findings suggest that exporting firms may lay off some workers who work in production for their shrinking domestic segments, while also engaging in some within-firm reallocation of workers. We also find that, even after controlling for productivity and export status, larger firms lay off more workers due to trade competition.     

Testing for unit roots: An empirical investigation

This paper compares some recent tests for unit roots in observed time series data. The results indicate some sensitivity to lag truncation and the alternative maintained hypothesis. A procedure is recommended for using the Dickey–Fuller tests.     

Offshoring and firm overlap: Welfare effects with non‐sharp selection into offshoring

Using German establishment data, we provide evidence for selection of larger, more productive producers into offshoring. However, the selection is not sharp, and offshoring and nonoffshoring producers coexist over a wide range of the revenue distribution. To explain this overlap, we set up a model of offshoring, in which we decouple offshoring status from revenues through heterogeneity in two technology parameters. In an empirical analysis, we employ German establishment data to estimate key parameters of the model and show that disregarding the overlap has large quantitative effects. It lowers the estimated gains from offshoring by almost 50% and, at the same time, exaggerates the role of the extensive margin for explaining the evolution of German offshoring since the 1990s.     

Strategic monetary and fiscal policy interactions: An empirical investigation

This paper identifies leadership regimes in monetary-fiscal policy interactions in three countries, the UK, the US and Sweden. We specify a small-scale, structural general equilibrium model of an open economy and estimate it using Bayesian methods. We assume that the authorities can act strategically in a non-cooperative policy game, and compare different leadership regimes. We find that the model of fiscal leadership gives the best fit for the UK and Sweden, while in the US the Nash or non-strategic regime dominates. We assess the extent to which policy maker preferences reflect microfounded social preferences.     

Credit information sharing and banking crises: An empirical investigation

We study the effect of credit information sharing on the likelihood of banking crises using a comprehensive cross-country dataset for the period from 1975 to 2006. The empirical analysis shows that credit information sharing reduces the likelihood of banking crises and it does more so in low income countries. The effect is statistically and economically significant, and applies to both public registries and private bureaus. Furthermore, we show that credit information sharing reduces the impact of rapid credit growth on banking crises. Specifically, rapid credit growth is less likely to lead to a banking crisis in countries with credit information sharing.     

The real exchange rate determination: An empirical investigation

This study examines the real exchange rate determination in Asian economies. The methods show that the real exchange rate and terms of trade can be jointly determined. Productivity differential, terms of trade, the real oil price, and reserve differential are found to be important in the real exchange rate determination in the long run. However, the significant impacts of those variables on the real exchange rate determination are different across economies. Moreover, the results of the generalised forecast error variance decompositions show that the important contributors of the real exchange rate are different across economies.     

Banking integration in ASEAN-6: An empirical investigation

Banking integration is widely considered as the last stepping stone of economic integration, especially at the regional level. This paper aims to introduce extended measures of banking openness and the overall balanced degree of integration through capital flows. Using the quarterly data from the ASEAN-6 economies (Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) from 1996Q4 to 2016Q4, the obtained empirical results reveal that: (i) the degree of banking openness, which measures the total inflows and outflows divided by the total banking assets of the given country, remains low and even slightly decreases, despite the increasing cross-border banking and greater economic links among ASEAN-6; (ii) the overall degree of balance, which calculates the balance and the diversification of outward and inward integration, fluctuates over time but reaches the well-balanced level. Furthermore, the research highlights main drivers of the banking integration in this region, such as regulatory quality, bank size and the global credit risk. These findings have important policy implications for banking stability and integration in ASEAN-6.     

Determinants of terrorism in Pakistan: An empirical investigation

The purpose of this study is to analyze the determinants of terrorism in the context of Pakistan. The determinants of terrorism include various socio-economic variables like GDP per capita, unemployment, political rights, inflation, poverty, inequality and literacy level. A long-run relationship between the variables is analyzed by applying Johansen co-integration technique. The Error Correction Model (ECM) is applied to determine the stability of the long run relationship between terrorism and various variables and also to streamline the short-run and long run impacts of the variables on terrorism. In general, the results revealed that there exists a long run relationship between various social and economic variables and terrorism while the results of ECM revealed that about 89% convergence towards equilibrium takes place every year. Similarly, important results are obtained by short run and long run elasticities estimated under the Error Correction Model. Impulse response analysis reveals that the impacts of one standard deviation shock given to random disturbances on the systems of variables have mixed results. Some variables have increasing trend over the time period, some have decreasing trends, while some have fluctuating and cyclical trends.     

Government size,democracy, and corruption: An empirical investigation

Previous studies on the effect of government size on corruption have produced mixed results. In an attempt to explain these ambiguous results, this study investigates the effect of government size on corruption by taking into account the role of the democracy in each country. Using annual data of 82 countries between 1995 and 2008, the estimation results indicate that an increase in government size can lead to a decrease in corruption if the democracy level is sufficiently high and, in contrast, can lead to an increase in corruption if it is too low. As robustness checks, the estimations using a different index of corruption and a different proxy for government size are also conducted. The results reveal that our main findings are robust. Furthermore, to address endogeneity problems, we conduct the instrumental variables estimation and the system generalized method of moments estimation, the results of which also support our primary findings. These results provide some important implications for policymakers seeking to perform government interventions without aggravating corruption.     

Bank lending and interest on excess reserves: An empirical investigation

This paper econometrically tests for effects on bank lending of the Federal Reserve’s policy of paying interest on excess reserves (IOER). Following the 2008 financial crisis, US banks decreased their loan allocations and increased holdings of excess reserves. A model of bank asset allocation shows that when the rate of IOER is higher than other short-term rates, banks will switch from zero excess reserves to a regime with higher excess reserves and lower lending. Using a sample of panel data on US banks from 2000 through 2018, we find evidence of a switch to a positive excess reserve regime in the post-crisis period. Controlling for market interest rates, loan demand, and economic activity, we find that IOER accounts for the majority of the decline in bank lending after the financial crisis.     

An empirical investigation of labor income processes

In this paper, I reassess the evidence on labor income risk. There are two leading views on the nature of the income process in the current literature. The first view, which I call the “Restricted Income Profiles” (RIP) process, holds that individuals are subject to large and very persistent shocks, while facing similar life-cycle income profiles. The alternative view, which I call the “Heterogeneous Income Profiles” (HIP) process, holds that individuals are subject to income shocks with modest persistence, while facing individual-specific income profiles. I first show that ignoring profile heterogeneity, when in fact it is present, introduces an upward bias into the estimates of persistence. Second, I estimate a parsimonious parameterization of the HIP process that is suitable for calibrating economic models. The estimated persistence is about 0.8 in the HIP process compared to about 0.99 in the RIP process. Moreover, the heterogeneity in income profiles is estimated to be substantial, explaining between 56 to 75 percent of income inequality at age 55. I also find that profile heterogeneity is substantially larger among higher educated individuals. Third, I discuss the source of identification—in other words, the aspects of labor income data that allow one to distinguish between the HIP and RIP processes. Finally, I show that the main evidence against profile heterogeneity in the existing literature—that the autocorrelations of income changes are small and negative—is also replicated by the HIP process, suggesting that this evidence may have been misinterpreted.     

An empirical investigation of organizational memetic variation

The potential of a theory based on organizational memes in coevolution with the environment has been postulated, but remains empirically under-developed. This study explores whether understanding organizational memetic variation is empirically possible and, if so, whether it might, with further development, provide managers with early indications of a misalignment between organizational action (operationalized as memetic variation) and strategic intent—the amount of memetic variation needed to stay aligned with the competitive environment. A method for empirically identifying knowledge-based memes in everyday practice is developed. It stems from modern advances in genetics allowing micro-level changes in genes to be linked to macro-environmental dynamics. Using the concept that memetic variation is caused by everyday, uncontrollable uncertainties of interpretation, memetic variation is reduced to seven categorical types. A highly exploratory quasi-experimental design allows a preliminary comparison of a would-be innovative ‘Portfolio Management Committee’ with self-organizing Internet chat-room settings that are representational of open-source innovation. Results are consistent with predictions showing that higher levels of variation are seen in the latter, despite the former’s strategic intent of innovating to stay aligned with a dynamic environment. Further work is needed, however, to test reliability and validity.
