Production and Growth

Why Productivity Is So Important • Productivity refers to the amount of goods and
services that a worker can produce from each hour of work.

How Productivity Is Determined • The inputs used to produce goods and services
are called the factors of production. • The factors of production directly determine

THE ECONOMY’S INCOME AND EXPENDITURE
• When judging whether the economy is doing well or poorly, it is natural to look at the total income that everyone in the economy is earning.

研究对象
宏观经济学主要关注整个经济体系的总体运行，包 括总需求、总供给、国民收入、物价水平、就业和 经济增长等。
宏观经济学与微观经济学的关系
相互联系
宏观经济学和微观经济学是经济学的两个重要分支，它们之间相互联系、相互补充。 微观经济学是宏观经济学的基础，而宏观经济学则是微观经济学的延伸和扩展。
区别
开放经济下的政策目标
货币政策与财政政策
实现内外部经济均衡，即国内经济增长、充 分就业、物价稳定和国际收支平衡。
在开放经济下，政府可以运用货币政策和财 政政策来调节经济，但需要考虑汇率和国际 收支等因素。
汇率政策
国际经济政策协调
政府可以通过调整汇率水平来影响国际经济 活动和国内经济状况。
各国政府需要加强国际经济政策协调，共同 应对全球性经济问题，促进世界经济稳定发 展。
支持通货膨胀
凯恩斯主义宏观经济学派认为，适度的通货膨胀可以刺激 经济增长，政府可以通过控制货币供应量等手段来调节通 货膨胀率。
货币主义宏观经济学派
强调货币供应量
货币主义宏观经济学派认为，货币供应量的变化是影响经济波动 的主要因素，政府应该通过控制货币供应量来调节经济。
主张单一规则
该学派主张政府应该制定一个固定的货币增长规则，并严格执行， 以保持物价的稳定和经济的增长。
VS
政策效应互补
货币政策和财政政策在调控经济时具有不 同的特点和优势，可以相互补充、协调配 合，提高宏观调控效果。例如，在治理通 货膨胀时，可以采取紧缩性货币政策和扩 张性财政政策相配合的方式；在促进经济 增长时，可以采取扩张性货币政策和紧缩 性财政政策相配合的方式。

一、什么是宏观经济学？
• 宏观经济学（macroeconomics）：研究总体经济变量 的经济学。
• 宏观经济学的主要研究对象：
– 经济增长（economic growth） – 失业（unemployment） – 通货膨胀（inflation） – 国际收支与汇率(balance of payments and exchange rate)
在某一既定时期一个国家内生产的所有最终物品和劳 务的市场价值
最终物品：为终端使用者所准备 中间物品：生产其他物品的一种组成成份或要素 GDP只包括最终产品—生产过程中使用的中间物 品的价值已经包含在最终物品的价值中
一国收入的衡量

国内生产总值 (GDP)：
在某一既定时期一个国家内生产的所有最终物品和劳 务的市场价值
微观经济学与宏观经济学之间的联系（ Linkage ）
微观经济学是宏观经济分析的基础（ Foundation ）
经济作为一个整体的行为（宏观）是以构成经济的个别单位（微观）的行 为为基础的。微观经济学关心资源配置(The allocation of resources)；宏观 经济学关心资源利用(The utilization of resources)。

How Productivity Is Determined
Human capital per worker is the economist’s term for the knowledge and skills that workers acquire through education, training, and experience. Like physical capital, human capital raises a nation’s ability to produce goods and services.
The factors of production directly
How Productivity Is Determined
Physical capital per worker is the stock of equipment and structures that are used to produce goods and services. Physical capital includes:
Production and Growth
Productivity refers to the amount of goods and services produced from each unit of labor input. A nation’s standard of living is determined largely by the productivity of its workers.
How Productivity Is Determined
Natural resources are inputs used in production that are provided by nature, such as land, rivers, and mineral deposits.
How Productivity Is Determined
The inputs used to produce goods and services are called the factors of production. The factors of production include:
Physical capital Human capital Natural resources Technological knowledge
Table 1 The Variety of Growth Experiences
ECONOMIC GROWTH AROUND THE WORLD
Living standards, as measured by real GDP per person, vary significantly among nations. The poorest countries have average levels of income that have s for many decades. Annual growth rates that seem small become large when compounded for many years. Compounding refers to the accumulation
Renewable resources include trees and forests. Nonrenewable resources include petroleum and coal.
Natural resources can be important but are not necessary for an economy to be highly productive in producing goods and
Tools used to build or repair automobiles. Tools used to build furniture. Office buildings, schools, etc.
Physical capital is a produced factor of production.

Production and Growth
A country’s standard of living depends on its ability to produce goods and services. Within a country there are large changes in the standard of living over time. In the United States over the past century, average income as measured by real GDP per person has grown by about 2 percent per year.
Productivity: Its Role and Determinants
Why Productivity Is So Important
Productivity plays a key role in determining living standards for all nations in the world. To understand the large differences in living standards across countries, we must focus on the production of goods and services.
