Are patent fees effective at weeding out low‐quality patents?

The paper investigates whether patent fees are an effective mechanism to deter the filing of low‐quality patent applications. The study analyzes the effect on patent quality of the Patent Law Amendment Act of 1982, which resulted in a substantial increase in patenting fees at the U.S. Patent and Trademark Office. Results from a series of difference‐in‐differences regressions suggest that the increase in fees led to a weeding out of low‐quality patents. About 10% of patents in the lowest quality decile were filtered out, with the effect concentrated in the patents of firms whose overall patent portfolio was medium to large (more than 20 patents). The study has strong policy implications in the current context of concerns about declines in patent quality.     

The Dynamics of Capital Structure in Transition Economies

This paper uses a dynamic unrestricted capital structure model to examine the determinants of the private companies' target financial leverage and the speed of adjustment to it in two transition economies, the Czech Republic and Bulgaria. We explicitly model the adjustment of companies' leverage to a target leverage, and this target leverage is itself explained by a set of factors. The panel data methodology combines cross-section and time-series information. The results indicate that the Bulgarian corporate credit markets were less supply -constrained than those of the Czech Republic during the period under investigation. Bulgariancompanies adjusted much faster to the target leverage than Czech firms. The speed ofadjustment related positively to the distance between target and observed ratio for Bulgarian companies while the relationship was neutral for Czech companies. The conservative policies of Czech banks and the exposure control were likely responsible for the slower adjustment among the larger companies while the opposite were true for Bulgarian banks and companies.     

Board composition, regulatory regime and voluntary disclosure

This study, which examines the association between board monitoring and the level of voluntary disclosure, finds new evidence that firms with a higher proportion of independent directors on the board are associated with higher levels of voluntary disclosure. Although board size and CEO duality are not associated with voluntary disclosure, boards with a majority of independent directors have significantly higher levels of voluntary disclosure than firms with balanced boards. Notably, we find that the presence of an external governance mechanism, the regulatory environment, enhances the strength of the association between the proportion of independent directors and the level of voluntary disclosure. This association is some two to three times greater under a “disclosure-based” regulatory regime than under a “merit-based” regulatory regime.     

Technology gap,imported capital goods and productivity of manufacturing plants in Sub-Saharan Africa

This paper uses firm-level data from Ghana, Tanzania and Kenya to examine the effect of capital goods imports on domestic firms' productivity, and the role firms' technology gap plays in aiding the transmission of knowledge embodied in capital goods to domestic firms. The results show that increasing imports of capital goods and closing technology gaps have positive effects on productivity. Furthermore, domestic firms with technology standards farther from international best practices benefit more from capital goods imports. The results also imply that trade liberalization policy aimed at eliminating tariffs on capital goods will significantly improve the performance of technically incompetent firms in the African manufacturing sector.     

The third post-world war II wealth bubble

Business Economics - The United States has now experienced three major wealth bubbles since 1945. The first two peaked in 1999 and 2006, followed by crash and recession. By 2018, peaks were higher...     

TAXATION IN MATCHING MARKETS

We analyze the effects of taxation in two-sided matching markets where agents have heterogeneous preferences over potential partners. Our model provides a continuous link between models of matching with and without transfers. Taxes generate inefficiency on the allocative margin, by changing who matches with whom. This allocative inefficiency can be nonmonotonic, but is weakly increasing in the tax rate under linear taxation if each worker has negative nonpecuniary utility of working. We adapt existing econometric methods for markets without taxes to our setting, and estimate preferences in the college-coach football market. We show through simulations that standard methods inaccurately measure deadweight loss.     

Macroeconomic Announcements and the Distribution of Price-Endings in the U.S. Treasury Market

We investigate how new information impacts quote clustering in the bond market. We find that clustering, along with quote activity, price volatility and bid-ask spreads, increases sharply in the minutes following releases of macroeconomic news. Each returns to near-normal levels within the hour. Effects are strongest for more liquid on-the-run notes and for the announcements typically associated with substantial information flow. The strong positive comovement of clustering, quote activity, price volatility, and bid-ask spreads supports the conclusion that innovations of these variables are endogenous to the arrival and incorporation of information into prices.     

The unrealized value of incentivized eWOM recommendations

While companies have recognized the perceived economic benefits of encouraging and managing electronic word-of-mouth (eWOM), the benefits may be understated. Companies take into account the influence on the audience. But, what about any effects on the person who communicates the eWOM? We explore the impact that incentivized eWOM has on communicator attitude. Using the saying is believing effect as our theoretical foundation, we suggest that providing eWOM induces a change in the communicator’s attitude. By generating and providing a biased recommendation, the communicator will believe the biased recommendation. Furthermore, the communicator is likely to remember the biased recommendation and will use it to update their attitude. We examine how valence of recommendations (negative versus positive) and the number of opportunities to recommend affect the change in attitude. Our findings indicate that providing recommendations changes communicator’s attitude. Implications of the results are discussed.     

Consumer Preferences for Coffee: Hot and Wet,or Quality and Flavor?

An econometric model is developed and estimated for all brands of coffee sold at the retail level in four supermarkets in Columbus, Ohio. These brands are segmented into 24 categories, and the four stores are classified into two groups, inner-city and suburban, based on 2010 census tract data. Using estimated measures of price-sensitivity, these 24 categories are further segmented into four groups to help guide and clarify the discussion. Estimated results show different purchasing patterns and different levels of price-sensitivity for inner-city and suburban shoppers. Further, these purchasing patterns and levels of price-sensitivity suggest alternative marketing strategies for retailers. Private-label coffee brands are shown to be quite competitive with many national brands, and indeed private-label brands command a market share among inner-city shoppers that is more than double that for the nation (21.95% vs. 9%).     

The Crash of 1882 and the Bailout of the Paris Bourse

The crash of the French stock market in 1882 presented the Paris Bourse with its worst crisis of the nineteenth century. Its structure was similar in key respects to today’s futures markets, with a dominant forward market leading the Bourse to adopt a common fund to guarantee transactions and liquidity. While this mutualization of risk protects clients and brokers from idiosyncratic shocks, it is generally assumed that it also provides considerable protection against systemic shocks, as no twentieth century exchange has been forced to shut down. Using new archival data, this paper shows how a stock market crash overwhelmed the Bourse’s common fund. Only an emergency loan from the Bank of France, intermediated by the largest banks, prevented a closure of the Bourse.
