**Resource Allocation**

Resource allocation refers to the process of distributing scarce resources among various competing uses. It involves determining what goods and services should be produced and in what quantities. This decision is influenced by factors such as consumer preferences, production capabilities, and resource availability.

**Choice of Technique of Production**

The choice of technique of production refers to the decision regarding the methods and technology used to produce goods and services. Different techniques may require varying levels of capital, labor, and other resources. The choice of technique affects the efficiency and productivity of production processes, as well as the types and quantities of goods and services that can be produced.

**Distribution**

Distribution refers to the way in which goods and services are allocated among individuals or groups within a society. It involves the process of dividing the output of production and ensuring that it reaches the consumers who value it the most. Distribution can be influenced by various factors such as income levels, wealth, social class, and government policies.

**Macroeconomics**

Macroeconomics is a branch of economics that deals with the overall performance and behavior of the economy as a whole. It focuses on studying aggregate variables such as national income, unemployment rates, inflation, and economic growth. While macroeconomics provides insights into the overall functioning of the economy, it does not specifically address the issue of what goods and services should be produced and how much.

**Explanation**

Resource allocation, choice of technique of production, and distribution are all related to the problem of what goods and services are produced and in what quantities. These decisions are primarily addressed in the field of microeconomics, which analyzes the behavior of individual consumers and firms.

Resource allocation involves determining how society's scarce resources, such as labor, capital, and natural resources, are allocated among different uses. This decision is influenced by factors such as consumer demand, production costs, and resource availability. For example, if there is high consumer demand for smartphones, resources may be allocated towards the production of smartphones rather than other goods.

The choice of technique of production refers to the decision of how goods and services are produced. It involves selecting the technology, machinery, and processes that are most efficient and cost-effective. Different techniques of production may require different levels of resources and can impact the quantity and quality of output. For instance, a firm may choose between manual labor and automation for a specific production process, depending on factors such as cost, productivity, and skill availability.

Distribution concerns the allocation of goods and services to individuals or groups within a society. It involves determining how the output of production is divided and ensuring that it reaches those who value it the most. Distribution can be influenced by various factors such as income inequality, social class, government policies (e.g., taxation and welfare programs), and market mechanisms (e.g., prices and competition). The goal is to achieve a fair and equitable distribution of resources and opportunities.

On the other hand, macroeconomics focuses on studying the overall performance and behavior of the economy as a whole. It analyzes aggregate variables such as national income, unemployment rates, inflation, and economic growth. While macroeconomics provides insights into the overall functioning of the economy, it does not specifically address the decisions regarding what goods and services should be produced and in what quantities.
