Innovative Work Practices (IWP’s)
Economics of High Performance Work Practices
Teams - Definition
• Team - group of workers who work at least in part together and whose work is complementary.
– Assembly line - interrelated work – Committee – Team members do not have to work on exactly the same task
• Gains from specialization
Teams - Benefits
– Members specialize but know how parts fit together
• Makes use of complementarities - “the whole is greater than the sum of the parts” • Sharing difficult physical tasks • Coordination across tasks • Knowledge transfer - most valuable when
– Team members have idiosyncratic information – This information is valuable to other team members

Teams - Costs
• Incentive dilution due to free rider effects
– When rewards are shared among team members, there is the 1/N effect or line-of-sight effect. Incentives fall rapidly with the number on the team – Could reward individuals to avoid this problem
•Measuring individual effort is difficult when production organized as a team •Cooperation is usually important, but often difficult to measure individually.
Teams - Costs
• Group decision making is inefficient
– Quicker decisions made by a single person – Committee design jokes – Often much more socialization
Incentives on Teams
• Team bonuses
– best when team size is small
• Profit sharing
– Unlikely to have incentive effects - therefore best viewed as risk sharing (why unions do not like it)
• Norms or peer pressure
– Unfortunately, teams can enforce inefficient norms as well
Team Design
• Team Size
– larger size larger free rider problem – larger size more information sharing – Larger size less communication
• Member rotation across teams
– benefit of information sharing – cost if person-specific human capital is important
Team Design
• Competition or Cooperation across teams?
– Teams will naturally be competitive with each other. – If cooperation is important, need coordinating mechanisms to mitigate a lack of cooperation
•cross-team coordinating groups may be required.
Worker Empowerment
• Lazear’s focus
– Ability to communicate – Ability to express opinions – Ability to make suggestions
Worker Empowerment
• Benefits
– Better information about preferences
•more efficient contracting over job characteristics, •nonmonetary compensation •pay
– Better development of implicit contracts
•Important with specifically trained workers
Worker Empowerment
• Benefits
– Generate creativity
•more important when workers have idiosyncratic information
– Belief that information will not be used against them
Costs Vs. Benefits of Worker Empowerment
• Costs – Productivity enhancement must be traded off against the workers’ increased bargaining power • Loss of rents to workers will occur • Firms typically resist unions for this reason – Workers are likely to be able to extract rents when they work together in a long term relationship

JOB DESIGN: TWO APPROACHES
• Classical: ex ante optimization (Taylorism) of methods – has substantial advantages if you can figure out best practices ex ante • effective use of central knowledge (e.g., talented engineers) • all workers use best practices • strong coordination & control (e.g., consistent output) • Modern: continuous improvement – more evolutionary approach • effective use of knowledge at lower levels • requires “knowledge management” to share best practices • creates coordination & control problems
When to Use Which Approach?
• What does NPV of ex ante optimization depend on? – costs: how difficult is the optimization? • how complex is the process? the product? the product line? • how stable was our history? have we already figured out best methods because we’ve done the same thing for a long time? • how predictable is the environment? do things change constantly? can we foresee all contingencies & plan for them? – benefits: • how stable & predictable is our future expected to be? is our technology changing rapidly? is competition dynamic? will we have to re-optimize soon? • Emphasize ex ante optimization if environment is simple, stable & predictable; otherwise emphasize continuous improvement • Consider the Classical approach as an investment – up-front cost of optimization, amortized over future productivity gains
Buzzwords: Classical v. Modern Jobs
• Why the trend toward “empowerment,” “TQM,” etc.? – industrial engineering less effective now more scope for continuous improvement • time based competition • complex product lines; frequent changes • rapid technological advances • emphasis on quality & service rather than cost – & job enrichment-type approaches tend to be more effective • information technology • cultural change? • This argument illustrates “External Fit” of HR policies w/ product, technology, & industry conditions
Notes on Classical v. Modern Jobs
• Not all jobs should be enriched – what can be routinized, usually should be – or even automated, computerized • Specialization & job enrichment are often balanced through job rotation • Firms generally use a mix of both centralized & decentralized approaches to process improvements – centralized tends to work better for major, one time changes (e.g., technology changes) • & improves knowledge management / transfer – decentralized tends to work better for incremental changes • & for implementation / tactics: decision management v. control – both may be needed for different types of adaptation
Implementation of Modern Job Design
1. Usually, focus on multi-tasking more than multi-skilling – what kind of learning? new skills v. process & product improvements 2. Bundle complementary jobs – doing • skills, information & equipment • proximity (physical or temporal) – results: parts or processes that work closely together – examples • repeat work for same client • direct relationships with client • vertical loading (“doing” v. “controlling” or reducing decision control) – focus on providing learning opportunities 3. Modularize the process (Task Identity)
Implementation
4. Decentralize (Autonomy + Feedback)
– b/c workers have more specific knowledge in enriched jobs – have employees collect performance metrics & monitor themselves – teach employees to identify problems, suggest solutions, experiment • e.g., Juran on TQM (1989) analyze symptoms theorize causes test theories establish causes simulate a remedy test remedy under operating conditions establish controls to hold the gain
Implementation
5. Choose other policies for “Internal Fit” – teams • to achieve modularity / Task Identity • for collaborative problem solving • cross training & job rotation – career policies • careful recruitment to achieve proper “Growth Need Strength” • cross training & job rotation • training – in particular, in problem solving – culture • overall goal / mission • teamwork – incentives • may not be needed • avoid punishment to encourage airing of problems & ideas
Quick Questions
• Are “Happy workers productive workers”? • Do extrinsic incentives destroy intrinsic motivation?
Economic (& Psychological) Ideas
• Specialization • Intrinsic motivation • Taylorism – ex ante optimization v. continuous improvement • Using enriched jobs to create specific knowledge • Internal fit between HR policies • External fit of HR policies with strategy & environment
Research Results on Innovative Work Practices
What Works at Work?
Innovative Work Practices Contrast with Traditional
• Traditional work practices
– tightly defined jobs with associated pay – clear lines of demarcation separating duties and rights of workers and supervisors – decision making retained by management – communication through formal chains of command
Expected Returns
• • • • Increased motivation Cross training reduces absenteeism costs Decentralization removes need for middle management Training in problem solving can assist in implementing new technology • Involvement in decisions can reduce grievances • Higher productivity - higher profits
Costs
• • • • Extra meetings Costs of HR practices Higher pay? Worker empowerment
How to study?
• Ideal experimental design
– Internal validity
• Explanations other than the current one can be ruled out •Requires random assignment of IWP’s
– External validity - how closely do research sites resemble the target population?
Problems
• Quality of workers/management may be correlated with results (omitted variable bias) + Self-selection (best managers implement plans) - last hope(something better work or we’re tubed) • Solution is typically to use longitudinal data and allow subjects to act as their own control
– requires study of adoption (diffusion) – requires study of survival of IWP’s
Problems
• Response bias - voluntary answering of questions typically has a very low response rate • Difficult to match results with correct unit of observation (Not all workers involved with IWP’s) • Measurement errors are probably large when categorizing IWP’s. They may not be the same from firm to firm
– Are results “self-serving?” - use two responses at different levels
• Bundles of practices often required - Are they substitutes (ESOP or profit sharing) or complements
Results
• 3/4ths of case studies report increased economic performance. This is not true for attitudes or behaviors. • Intra-industry studies in steel and auto
– whole system needs change
•more screening of workers •broader jobs •problem solving teams
Results
• Intra-industry studies in steel and auto
– whole system needs change
•gain sharing system •employment security
– large positive effects of bundles – individual changes do not get desired effects – few companies have been willing to adopt all
Why haven’t more done it?
• Best in greenfield site • Limited change tried and doesn’t work so it is abandoned • Union mistrust of management plans • Management fear of worker empowerment • Resistance of people who could lose (middlemanagement) • Lack of supportive public policy
