Business economics Study Guide

Productivity measures the efficiency of production, typically defined as output per unit of input over a given period. For labour, this is commonly expressed as output per worker or per hour worked. Increased productivity means more goods or services can be produced with the same amount of resources, leading to lower unit costs and potentially higher profits for firms. Division of labour, a key concept introduced by Adam Smith, involves breaking down the production process into several distinct tasks, with each worker specialising in a particular task. This specialisation can significantly boost productivity as workers become more skilled and efficient at their specific tasks, reduce time wasted switching between tasks, and facilitate the adoption of specialised tools and machinery. However, division of labour can also lead to drawbacks such as worker boredom, deskilling, and interdependency risks if one stage of production is disrupted.

Government intervention in markets refers to actions taken by public authorities to influence market outcomes. This can include policies such as taxes, subsidies, price controls (minimum or maximum prices), direct provision of goods and services, and regulation. Governments intervene for various reasons, including correcting market failures (e.g., externalities, public goods), achieving equity or income redistribution, and promoting macroeconomic stability. For example, a government might impose a tax on a good with negative externalities to reduce its consumption and internalize the external cost. Conversely, a subsidy might be provided for goods with positive externalities to encourage their consumption. Price controls aim to make goods more affordable for consumers (maximum price) or guarantee a minimum income for producers (minimum price), but can lead to shortages or surpluses respectively. The effectiveness of government intervention can be evaluated based on its ability to meet its objectives, potential unintended consequences, and the efficiency of resource allocation.
