Two Illustrations of the Quantity Theory of Money: Breakdowns and Revivals

Abstract: By extending his data, we document the instability of low-frequency regression coefficients that Lucas (1980) used to express the quantity theory of money. We impute the differences in these regression coefficients to differences in monetary policies across periods. A DSGE model estimated over a subsample like Lucas's implies values of the regression coefficients that confirm Lucas 's results for his sample period. But perturbing monetary policy rule parameters away from the values estimated over Lucas's subsample alters the regression coefficients in ways that reproduce their instability over our longer sample. (JEL C51, E23, E31, E43, E51, E52) Robert E. Lucas Jr. (1980) used near unit slopes of univariate regressions of moving averages of inflation and interest rates on money growth for the United States for the period 1953-1977 to illustrate "two central implications of the quantity theory of money: that a given change in the rate of change in the quantity of money induces (i) an equal change in the rate of price inflation; and (ii) an equal change in nominal rates of interest." Lucas said that those two quantity-theoretic propositions

The external knowledge sourcing process in multinational corporations

Abstract: Over the years, many multinational corporations (MNCs) have created overseas “scouting” units to tap into new ideas and opportunities in leading-edge markets, but with mixed outcomes. In this study, we describe the development of a European telecom firm's scouting unit in Silicon Valley during the 2000s, focusing on the specific approaches used by the scouting managers to build effective connections between Silicon Valley start-ups and the firm's business units back in Europe. We identify four distinct approaches for different types of opportunities, and we observe a clear sequencing of effort over time as the scouting managers built the necessary capabilities and credibility.

Do High-Frequency Traders Anticipate Buying and Selling Pressure?

Abstract: This study tests the hypothesis that high-frequency traders (HFTs) identify patterns that allow them to anticipate and trade ahead of other investors’ order flow. HFTs’ aggressive purchases and sales lead those of other investors. The effect is consistently stronger for a subset of HFTs and at times when non-HFTs are hypothesized to be less focused on disguising order flow. These results are not fully explained by HFTs reacting faster to signals that non-HFTs also observe such as news, contrarian or trend-chasing behavior by non-HFTs, and trader misclassification. These findings support the existence of an anticipatory trading channel through which HFTs may increase non-HFT trading costs.

Information in Accruals About the Quality of Earnings

Abstract: We extend the analysis in Sloan (1996) to identify the source of information in accruals about earnings quality. Our results indicate that information in accruals about earnings quality is not limited to the current accruals analyzed by Sloan, but extends to non-current accruals. We also show that while information in accruals originates almost exclusively from asset accruals, liability accruals play a useful role in helping to isolate information in asset accruals about earnings quality. Finally, we show that information in accruals about earnings quality originates from both growth in the scale of operations and deterioration in the efficiency of asset usage. Overall, our results indicate that total accruals, defined as the difference between earnings and free cash flows, provide an intuitive, robust and parsimonious measure of earnings quality. Contrary to existing studies, our results also indicate that the information in accruals about earnings quality is not attributable to a single factor, such as 'discretionary' accruals or firm growth.
