Competition, Innovation, and the Inverted U

Ronald Goettler

How does increased competition affect product innovation? A paper by senior associate dean Ronald Goettler, “Competition and Product Innovation in Dynamic Oligopoly,” tackles this important question, relevant to corporate strategy. Read more about Competition, Innovation, and the Inverted U.

Are Successful Entrepreneurs Just Lucky?

Claudio Loderer, Diego Liechti, and Urs Peyer

A new paper studies the role of sheer luck compared with talent, experience, education, and hard work in entrepreneurial performance. Read more about Are Successful Entrepreneurs Just Lucky?.

Online Reviews Prove Trustworthy

Huaxia Rui and Susan Lu

A new paper by assistant professors Huaxia Rui and Susan Lu suggests that despite media criticism to the contrary, online physician reviews can be trusted, at least those of cardiac surgeons. The paper, “Can We Trust Online Physician Ratings? Evidence from Cardiac Surgeons in Florida,” is the first to look systematically at the correlation between online ratings and medical performance. Read more about Online Reviews Prove Trustworthy.

Looking at Liquidity Before Litigation

Frank Torchio and Sunita Surana

A new paper by Simon adjunct lecturer Frank Torchio ’82S (MBA) and colleague Sunita Surana provides new insight into the proper way to perform a discounted cash flow valuation for fair-value assessments. Read more about Looking at Liquidity Before Litigation.

Upgrade Intervals Affect Profitability

Abraham Seidmann, Amit Mehra, and Probal Mojumder

In a new paper published by Production and Operations Management Journal, “Product Life Cycle Management of Packaged Software,” Simon professor Abraham Seidmann and co-authors Amit Mehra and Probal Mojumder study the optimal intervals between software upgrades and analyze how these intervals change over a product’s life cycle. Read more about Upgrade Intervals.

Consumer Curiosity Doesn't Guarantee a Sale

Paulo Albuquerque

If you go online to browse for a cutting-edge product—whether it’s an item that’s just being introduced or one with new bells and whistles—are you more likely to buy it the more you browse? Simon professor Paulo Albuquerque and two colleagues have been exploring questions about online consumer behavior like this for roughly four years. Read more about Consumer Curiosity.

Math Modeling Could Save Millions

David Tilson, Vera Tilson, Gregory Dobson, and Curtis Haas

A Simon Business School case study of production practices at Strong Memorial Hospital reveals the potential to save millions in production costs at hospital pharmacies across the nation. Read more about Math Modeling.

Pulse of Advertising

Dan Horsky and Marshall Freimer

A consumer products company comes out with a series of ads for a few months, takes a break, then airs a new set several months later. Inconsistent? Spotty? Turns out this is good for business. In their paper, “Periodic Advertising Pulsing in a Competitive Market,” Simon professors Dan Horsky and Marshall Freimer build a theoretical model showing that advertising in concentrated bursts, interspersed with breaks—called pulsing—is the best advertising strategy.

The Benefits of Debt

Toni Whited

One of the basic tenets taught in business school is that debt is a good thing for profitable firms. They reap desirable tax deductions from the interest they pay. Some of the research done on tradeoff theories of capital structure, however, predicts that debt is actually a detriment. Not so, says a study of the accounting data for publicly traded firms in the United States, written by Simon professor Toni Whited and her colleagues Andras Danis and Daniel Rettl. They argue that debt is a benefit. Read more about The Benefits of Debt.

Blue Firms Give More Green

Leonard Kostovetsky

Firms led by Democrats and headquartered in Democratic-leaning states spend significantly more on corporate social responsibility than do their Republican counterparts in Republican states, a Simon professor has found. While his finding didn’t surprise Leonard Kostovetsky, the extent of the spending did. He and co-author Alberta Di Giuli estimate that Corporate Social Responsibility (CSR) costs Democratic-leaning firms approximately $20 million more in annual SG&A expenses—or about 10 percent of net income—than GOP-led firms. Read more about Blue Firms Give More Green.

Competition Drives Cash

Boris Nikolov

Companies hold more cash than they used to. In the early 1980s, 10 percent of a firm’s assets were invested in Treasury bonds, cash accounts, and the like. These days, it’s more like 20 percent. In “Competition, Cash Holdings, and Financing Decisions,” Simon professor Boris Nikolov and co-authors Erwan Morellec and Francesca Zucchi build a model that provides a theoretical framework to figure out the benefits and costs of holding cash and test predictions generated by the model to help answer these questions.

Colluding Through Suppliers

Jeanine Miklós-Thal

In a new study, Assistant Professor Jeanine Miklós-Thal shows that retailers can collude more easily on the prices consumers pay by also agreeing among them to pay above-cost wholesale prices and slotting fees to their suppliers. “Colluding Through Suppliers” is the first to look at collusion on wholesale prices as a method to facilitate collusion on output prices.

Predicting the Entrepreneurs

Barry A. Friedman

What drives people to become entrepreneurs, particularly in countries with transitional economies? The question is of special interest to Simon School lecturer Barry A. Friedman. He has a doctorate in Industrial and Organizational Psychology, and teaches abroad during breaks. Dr. Friedman is interested in how the role of entrepreneurship differs among economies. Read more about Predicting the Entrepreneurs.

Multimarket Competition

Guy Arie

New research by Simon School assistant professor Guy Arie brings a fresh look at competition among firms that operate in multiple markets. Multimarket firms, common in the United States and world economy, compete in more than one market but don’t overlap in all markets. Companies move in and out of markets all the time as they expand sales and acquire other firms. The decisions they make about price, quantity, and other facets of product management expand or reduce their presence in various regions.  Read more about Multimarket Competition.

Socializing and Advertising

Mitchell Lovett

Media companies seeking new ways to promote their products—television shows in particular—will find new insight in recent research by Simon School assistant professor Mitchell Lovett. Lovett and co-author Richard Staelin of Duke University studied the roles that social engagement and advertising play in building entertainment brands.  Read more about Socializing and Advertising.

Comparing Bank Financing and Trade Credit

Abraham Seidmann

A new paper by Simon professor Abraham Seidmann and Professor Bing Jing of Cheung Kong Graduate School of Business, “Finance Sourcing in a Supply Chain,” examines the merits of trade versus bank credit between a manufacturer and a retailer with limited capital. The study adds critical new insights to an active research area that has important managerial implications.

Timing, Timing, Timing

Paulo Albuquerque and Yulia Nevskaya

Scheduling product innovation is one of the toughest tasks managers tackle. How long should a TV series last, for example? How frequently should video game updates be released? At its core, the answer lies in knowing why and how consumers are using the product. In a new paper, “The Impact of Innovation on Product Usage: A Dynamic Model with Progression in Content Consumption,” Paulo Albuquerque, associate professor of marketing, and doctoral candidate Yulia Nevskaya built a model that both explains how consumers make decisions about products that undergo regular updates and provides insights on product innovation.

The Word of Mouth Speaks

Mitchell Lovett

What is it about brands that drive word of mouth? Many studies have been done about word-of-mouth (WOM) marketing, and more still on brands. Though both are central concepts in marketing, surprisingly little research has focused on the role of brands in word of mouth. Mitchell J. Lovett, assistant professor of marketing, is a co-author of a new study that is the first to explore the relationship between them. Lovett produced on “On Brands and Word-of-Mouth” with Renana Peres of Hebrew University of Jerusalem and Ron Schachar of IDC Herzliya’s Arison School of Business.

Patients Prefer Same Gender

Ryan McDevitt

Competition for patients among urology physicians groups has a direct effect on women’s health, a new study has found. Ryan McDevitt, assistant professor of economics and management, and James Roberts of Duke University, co-authored “Market Structure and Gender Disparity in Health Care: Preferences, Competition, and Quality of Care.”

Understanding Incentive

Jeanine Miklós-Thal

Jeanine Miklós-Thal and co-author Hannes Ullrich were looking for a way to test whether future career prospects affect current effort incentives when they hit upon the perfect testing ground: European soccer. “Soccer is a nice way to test these incentives,” says Miklós-Thal, assistant professor of economics and marketing at the Simon School. “You need an environment where some people have a chance to be promoted and others do not. You can’t test the same thing in a business environment.” Read more about Understanding Incentive.

Banks and Short-Term Borrowing

Joanna Shuang Wu and Edward L. Owens

Simon School professors Joanna Shuang Wu, associate professor of accounting, and Edward L. Owens, assistant professor of accounting, set out to investigate for themselves whether a large sample of bank-holding companies were indeed window-dressing leverage numbers to mask fluctuations during the quarter. They also wanted to see if the market knew—and if it cared. Read more on "Banks and Short-Term Borrowing."

Just How Big is Wal-Mart’s Impact

Paul Ellickson

Paul Ellickson,Simon School assistant professor of economics and of marketing, who studies the economics of retail competition, researched the question with Paul Grieco of Pennsylvania State University, in “Density versus Differentiation: The Impact of Wal-Mart on the Grocery Industry". Read more on "Density versus Differentiation: The Impact of Wal-Mart on the Grocery Industry."
