So far, our work on data science problems has primarily involved applying statistical techniques to analyze the data and derive some conclusions or insights. But there are times when it is not as simple as that. Sometimes we want to learn something from that data and use that learning or knowledge to solve not only the current problem but also future data problems. We might want to look at shopping data at a grocery chain, combined with farming and poultry data, and learn how supply and demand are related. This would enable us to make recommendations for investments in both the grocery store and the food industries.

In the previous chapter, we saw how to learn from data when the labels or true values associated with them are available. In other words, we knew what was right or wrong and we used that information to build a regression or classification model that could then make predictions for new data. Such a process fell under supervised learning. Now, we will consider the other big area of machine learning where we do not know true labels or values with the given data, and yet we will want to learn the underlying structure of that data and be able to explain it. This is called unsupervised learning.

This chapter covers internal constraints on pay, as opposed to the external constraints (namely labor law) covered in Chapter 4. Much is said about collective bargaining agreements in unionized settings, and the effect of unions on pay and pay dispersion. From the standpoint of managers, internal and external constraints are nearly identical in that both are sets of rules that must be followed to avoid negative consequences. One difference is that internal constraints are often more amenable to managerial influence; for example, collective bargaining agreements are renegotiated every few years, and management participates. The 3 Cs of compensation constraints are revisited in the context of internal constraints, as are compensation floor and ceilings. Pay compression is discussed, given its prevalence in unionized settings. Diverse preferences in the union membership are addressed in the context of a vote on seniority-based layoffs versus across-the-board temporary wage cuts, i.e., furloughs. Other (non-union) internal constraints are covered, such as those imposed on individual establishments by corporate headquarters, and company-wide design of the benefits package in pay plans.

This chapter instills an appreciation for the powerful effects (both positive and negative) of performance pay on employee behavior. It opens with a performance-pay success story, namely a field experiment by Shearer (2004) in which the piece-rate compensation of Canadian tree planters was changed. It then develops some examples of the darker side of performance pay, including the Wells Fargo employees who opened false accounts to meet a quota. Section 9.2 provides visual representations of performance pay in which the pay graph has a positive slope (i.e., it increases when the worker’s performance measure increases), sometimes linearly as with piece-rate pay and sometimes nonlinearly as with bonuses. The chapter emphasizes the incentive and sorting effects associated with performance pay as well as its prevalence. Workers’ attitudes towards risk (of earnings fluctuations) and how risk affects performance pay is covered, along with performance measurement, various drawbacks of performance pay, and how to design performance-pay contracts. Readers will finish the chapter with an understanding of the advantages and disadvantages of performance pay and when it can be effectively used.

This chapter introduces some terminology and themes that pervade the book. Compensation is defined broadly to include everything a worker likes about the job. “Strategic compensation” is about managing the compensation system to advance a specific organizational objective, typically profit maximization. The chapter discusses how this relates to talent management, turnover, retention, and employee productivity. Four recurring themes are introduced: (1) “Incentive effects” and “sorting effects (both of which affect the company’s labor productivity) arise when the compensation system is changed; (2) Market competition largely dictates pay levels, whereas employers have more control over pay design; (3) Competition forces employers to care about their employees’ preferences about pay; (4) Bargaining power also affects pay levels. The metaphor of a “3-legged stool” is introduced, in which compensation depends on workers’ desires, skills, and mobility. There’s discussion of what constitutes “fair” pay and the tradeoffs associated with allowing employees to know each other’s pay versus keeping compensation secret. The appendix offers a detailed treatment of nominal versus real compensation.
