In this study, we follow the strategy typology proposed by Treacy and Wiersema (1995) and develop a textual measure of firms’ generic strategy along three dimensions: product leadership, customer intimacy, and operational excellence. Product-leadership firms emphasize innovation and confront high congestion risk caused by rapid growth. We hypothesize that these firms adopt a more rigid cost structure with higher fixed and lower variable costs to promote innovation and reduce congestion risk. Consistent with our prediction, we find that productleadership firms exhibit higher cost rigidity than customer-intimacy and operational-excellence firms. This finding is robust to using a difference-in-difference approach based on a quasi-natural shock caused by the adoption of the Inevitable Disclosure Doctrine. Furthermore, we find that the effects of the three strategies on cost structure are intensified by R&D investment, customer concentration, and asset utilization, respectively. Collectively, our findings suggest that organizational strategy has a significant impact on firms’ resource commitments and capacity choices.
Alex: Innovation-focused companies may be less able to shrink their costs when demand falls. This study finds that their costs are less flexible than those of companies emphasizing customer relationships or operating efficiency.
Sam: That sounds like a consequence of how companies compete, not just how carefully they manage spending. What kind of evidence are we discussing?
Alex: It’s an observational study by Rajiv Banker and colleagues, in a May 2021 manuscript. They analyze public companies’ business descriptions and connect their strategic priorities to how operating costs move with sales.
Sam: For researchers studying company performance, that could change how we interpret a cost increase or a slow response to falling sales.
Alex: And it offers strategy researchers a measure that doesn’t start with accounting numbers. We’ll follow how the authors read strategy from disclosures, what the cost comparisons show, and where the causal argument remains uncertain.
Sam: Before the measurement, what makes this question unresolved? Researchers already study business strategy and company performance.
Alex: The authors say the link to resource allocation and cost management has received less attention. They focus on cost structure: the balance between fixed costs and costs that vary with output. Strategy might help explain that balance.
Sam: Fixed costs can sound like buildings and machinery. Does their argument extend to people?
Alex: Yes. Highly trained employees can be costly to replace or release in the short run. That makes their costs relatively fixed. Direct materials are easier to adjust as demand changes, making their costs more variable.
Sam: So “fixed” depends on the adjustment horizon. And having more fixed costs isn’t automatically bad.
Alex: The paper calls that balance cost rigidity: more fixed costs and fewer variable costs. When sales grow, those fixed costs don’t grow alongside them, supporting profitability. When sales decline, a more flexible structure allows larger cost savings.
Sam: How do the authors distinguish strategies without defining them using the very costs they want to explain?
Alex: That’s the methodological contribution. Earlier accounting approaches use measures such as sales, spending, and employee counts to characterize strategy. If the outcome also uses accounting numbers, the relationship can partly arise mechanically from shared ingredients.
Sam: Public descriptions avoid those shared ingredients. But companies can describe themselves in flattering language. What do the authors actually extract?
Alex: They use the business section of annual filings, known as Form ten-K. It describes products, services, and strategic positioning. They count words about strategic concepts and the activities supporting them, then divide those counts by the section’s length.
Sam: Give us a concrete example of language that carries more information than a company simply calling itself successful.
Alex: Innovation, research and development, patents, and human capital contribute to their product-leadership measure: competing through new products. Customer service, customization, brands, and advertising help identify customer intimacy. Cost reduction and efficiency language help identify operational excellence.
Sam: Those categories sound theory-driven. How much of the final classification comes from the authors deciding which company belongs where?
Alex: They don’t assign each company to a single box. They group related keyword counts and use principal component analysis, which summarizes correlated measurements into fewer dimensions. The resulting patterns match the strategy framework of Treacy and Wiersema.
Sam: So each firm gets a score along each dimension. What tells us those scores reflect activity, rather than just vocabulary?
Alex: The validation comparisons help. Product leadership predicts more research spending, customer intimacy predicts more advertising, and operational excellence predicts more capital spending. Those associations appear in both current and subsequent years.
Sam: Strategy should also persist longer than a change in writing style. Do the scores show that?
Alex: Each score’s correlation with its previous-year value exceeds eighty percent. They also compare their scores with an earlier accounting-based strategy measure. The customer dimension captures something that older measure largely misses: cultivating customer relationships.
Sam: Let’s move to the cost result. How broad is the sample, and what counts as a rigid cost structure?
Alex: The filings span 1993 through 2019. After requiring financial data, the analysis includes about sixty-two thousand company-year observations. Greater rigidity means operating costs respond less strongly to a given proportional change in sales.
Sam: That’s an inferred balance of fixed and variable costs, then, rather than a direct inventory of every resource commitment.
Alex: Yes. In the adjusted model, a unit increase in the product-leadership score lowers the estimated cost response by roughly seven hundredths. Customer intimacy and operational excellence point the other way, toward costs that move more closely with sales.
Sam: That number isn’t a percentage saving. It describes the response of costs to sales, and its practical size depends on how far the strategy score changes.
Alex: The clearest takeaway is the contrast in direction. The model accounts for demand uncertainty, asset and employee intensity, and other company characteristics. Product leadership remains associated with greater rigidity; the other strategies remain associated with greater flexibility.
Sam: Why would innovators commit more resources when their research outcomes are uncertain? Flexibility could seem especially valuable there.
Alex: The authors propose two reasons. Research requires committed resources, including experienced scientists and expensive equipment. Product leaders may also grow rapidly, creating congestion risk: demand exceeds available capacity. Committing capacity beforehand can reduce that risk.
Sam: But firms with specialized staff might both describe themselves as innovative and have rigid costs. How do the authors strengthen the argument beyond that association?
Alex: They examine state courts’ adoption of the inevitable disclosure doctrine. This can prevent an employee taking a similar job if doing so would inevitably reveal trade secrets. The authors treat adoption as a shock that strengthens protection for strategic activities.
Sam: Their prediction is that protected firms lean further into their existing strategies. Do costs then move in the corresponding directions?
Alex: The difference-in-differences analysis supports that pattern. Product leadership becomes more strongly associated with rigidity after adoption. The other strategies move toward greater flexibility. That reinforces the baseline result, though the evidence is less precise for customer intimacy.
Sam: The doctrine also reduces employee mobility. Could that affect resource adjustment directly, rather than only through strategy?
Alex: That’s a reason to keep the causal conclusion qualified. The excerpt doesn’t establish that strategy is the doctrine’s only route to costs. And the textual measure itself assumes firms use more strategy-related language when they implement that strategy.
Sam: Do the more detailed comparisons fit the proposed mechanisms, or does the story stop at the overall association?
Alex: The product-leadership association is stronger among research-intensive firms. Customer intimacy is more strongly linked to flexibility when sales depend on concentrated customers. Operational excellence shows a stronger flexibility association where asset utilization is low.
Sam: Are those subgroup differences equally convincing?
Alex: No. The customer-concentration difference has a p-value around point zero eight, so I’d treat it as suggestive. The authors also find stronger strategy associations under greater demand uncertainty and smaller market shares.
Sam: We started with falling demand. Does the paper distinguish having rigid capacity beforehand from deciding not to cut resources afterward?
Alex: It does. Cost stickiness means costs fall less when sales decline than they rise when sales increase. That concerns adjustments after demand is observed. Product leaders show more stickiness; customer-intimacy and operational-excellence firms show less.
Sam: So the evidence connects strategy to both capacity commitments and subsequent adjustment. Who should read the full document, and where should they start?
Alex: Researchers measuring strategy should start with the textual-measure construction and validation sections. Researchers studying cost behavior should read the baseline analysis alongside the legal-shock analysis, then the cost-stickiness section. Keep disclosure-based measurement and causal identification separate as you read.
Sam: And what should everyone else remember?
Alex: In this sample, how companies compete is associated with how readily they can adjust their resources. A less flexible cost base may reflect a commitment to innovation, not simply poor cost control.
Sam: That’s a useful distinction to carry into the next company-performance study.
